I'm trying to install some packages with pip.
But pip install unroll gives me
Command "python setup.py egg_info" failed with error code 1 in
C:\Users\MARKAN~1\AppData\Local\Temp\pip-build-wa7uco0k\unroll\
How can I solve this?
About the error code
According to the Python documentation:
This module makes available standard errno system symbols. The value of each symbol is the corresponding integer value. The names and descriptions are borrowed from linux/include/errno.h, which should be pretty all-inclusive.
Error code 1 is defined in errno.h and means Operation not permitted.
About your error
Your setuptools do not appear to be installed. Just follow the Installation Instructions from the PyPI website.
If it's already installed, try
pip install --upgrade setuptools
If it's already up to date, check that the module ez_setup is not missing. If it is, then
pip install ez_setup
Then try again
pip install unroll
If it's still not working, maybe pip didn't install/upgrade setup_tools properly so you might want to try
easy_install -U setuptools
And again
pip install unroll
Here's a little guide explaining a little bit how I usually install new packages on Python + Windows. It seems you're using Windows paths, so this answer will stick to that particular SO:
I never use a system-wide Python installation. I only use virtualenvs, and usually I try to have the latest version of 2.x & 3.x.
My first attempt is always doing pip install package_i_want in some of my Visual Studio command prompts. What Visual Studio command prompt? Well, ideally the Visual Studio which matches the one which was used to build Python. For instance, let's say your Python installation says Python 2.7.11 (v2.7.11:6d1b6a68f775, Dec 5 2015, 20:40:30) [MSC v.1500 64 bit (AMD64)] on win32. The version of Visual Studio used to compile Python can be found here, so v1500 means I'd be using vs2008 x64 command prompt
If the previous step failed for some reason I just try using easy_install package_i_want
If the previous step failed for some reason I go to gohlke website and I check whether my package is available over there. If it's so, I'm lucky, I just download it into my virtualenv and then I just go to that location using a command prompt and I do pip install package_i_want.whl
If the previous step didn't succeed I'll just try to build the wheel myself and once it's generated I'll try to install it with pip install package_i_want.whl
Now, if we focus in your specific problem, where you're having a hard time installing the unroll package. It seems the fastest way to install it is doing something like this:
git clone https://github.com/Zulko/unroll
cd unroll && python setup.py bdist_wheel
Copy the generated unroll-0.1.0-py2-none-any.whl file from the created dist folder into your virtualenv.
pip install unroll-0.1.0-py2-none-any.whl
That way it will install without any problems. To check it really works, just login into the Python installation and try import unroll, it shouldn't complain.
One last note: This method works almost 99% of the time, and sometimes you'll find some pip packages which are specific to Unix or Mac OS X, in that case, when that happens I'm afraid the best way to get a Windows version is either posting some issues to the main developers or having some fun by yourself porting to Windows (typically a few hours if you're not lucky) :)
It was resolved after upgrading pip:
python -m pip install --upgrade pip
pip install "package-name"
I got stuck exactly with the same error with psycopg2. It looks like I skipped a few steps while installing Python and related packages.
sudo apt-get install python-dev libpq-dev
Go to your virtual env
pip install psycopg2
(In your case you need to replace psycopg2 with the package you have an issue with.)
It worked seamlessly.
I got this same error while installing mitmproxy using pip3. The below command fixed this:
pip3 install --upgrade setuptools
Download and install the Microsoft Visual C++ Compiler for Python 2.7 from https://www.microsoft.com/en-in/download/details.aspx?id=44266 - this package contains the compiler and set of system headers necessary for producing binary wheels for Python 2.7 packages.
Open a command prompt in elevated mode (run as administrator)
Firstly do pip install ez_setup
Then do pip install unroll (It will start installing numpy, music21, decorator, imageio, tqdm, moviepy, unroll) # Please be patient for music21 installation
Python 2.7.11 64 bit used
Other way:
sudo apt-get install python-psycopg2 python-mysqldb
I had the same issue when installing the "Twisted" library and solved it by running the following command on Ubuntu 16.04 (Xenial Xerus):
sudo apt-get install python-setuptools python-dev build-essential
It's a dependency issue.
I tried running the following commands helped me sorting out the dependencies, in my case the dependency was
grpcio
pip3 install --upgrade pip
python3 -m pip install --upgrade setuptools
pip3 install --no-cache-dir --force-reinstall -Iv grpcio==1.36.1
pip3 install pulsar-client==2.7.0
remember you must have python3 installed in your system.
First try:
pip install unroll
For sure not work :)
Then Try:
pip2 install unroll
Still get error Try:
pip3 install unroll
If pip3 Worked then suggest to change configuration to use pip3 as pip because you will get a lot of issues as the modern now is Python3 = pip3 if you execute a script files.
I had the same problem.
The problem was:
pyparsing 2.2 was already installed and my requirements.txt was trying to install pyparsing 2.0.1 which throw this error
Context: I was using virtualenv, and it seems the 2.2 came from my global OS Python site-packages, but even with --no-site-packages flag (now by default in last virtualenv) the 2.2 was still present. Surely because I installed Python from their website and it added Python libraries to my $PATH.
Maybe a pip install --ignore-installed would have worked.
Solution: as I needed to move forwards, I just removed the pyparsing==2.0.1 from my requirements.txt.
I ran into the same error code when trying to install a Python module with pip.
#Hackndo noted that the documentation indicate a security issue.
Based on that answer, my problem was solved by running the pip install command with sudo prefixed:
sudo pip install python-mpd2
For me this worked
python3 -m pip3 install -U pip
you can also try
python -m pip install -U pip
pip3 install --upgrade setuptools
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with -m pip instead of running pip directly.
Use python3 -m pip "command", eg:
python3 -m pip install --user pyqt5
I tried all of the above with no success. I then updated my Python version from 2.7.10 to 2.7.13, and it resolved the problems that I was experiencing.
That means some packages in pip are old or not correctly installed.
Try checking version and then upgrading pip.Use auto remove if that works.
If the pip command shows an error all the time for any command or it freezes, etc.
The best solution is to uninstall it or remove it completely.
Install a fresh pip and then update and upgrade your system.
I have given a solution to installing pip fresh here - python: can't open file get-pip.py error 2] no such file or directory
next installation helps me:
pip3 install cython
This worked for me:
sudo xcodebuild -license
Upgrading Python to version 3 fixed my problem. Nothing else did.
I downloaded the .whl file from http://www.lfd.uci.edu/~gohlke/pythonlibs/ and then did:
pip install scipy-0.19.1-cp27-cp27m-win32.whl
Note that the version you need to use (win32/win_amd-64) depends on the version of Python and not that of Windows.
I had this problem using virtualenvs (with pipenv) on my new development setup.
I could only solve it by upgrading the psycopg2 version from 2.6.2 to 2.7.3.
More information is at https://github.com/psycopg/psycopg2/issues/594
I faced the same problem with the same error message but on Ubuntu 16.04 LTS (Xenial Xerus) instead:
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-w71uo1rg/poster/
I tested all the solutions provided above and none of them worked for me. I read the full TraceBack and found out I had to create the virtual environment with Python version 2.7 instead (the default one uses Python 3.5 instead):
virtualenv --python=/usr/bin/python2.7 my_venv
Once I activated it, I run pip install unirest successfully.
try on linux:
sudo apt install python-pip python-bluez libbluetooth-dev libboost-python-dev libboost-thread-dev libglib2.0-dev bluez bluez-hcidump
Had the same problem on my Win10 PC with different packages and tried everything mentioned so far.
Finally solved it by disabling Comodo Auto-Containment.
Since nobody has mentioned it yet, I hope it helps someone.
I had the same problem and was able to fix by doing the following.
Windows Python needs Visual C++ libraries installed via the SDK to build code, such as via setuptools.extension.Extension or numpy.distutils.core.Extension. For example, building f2py modules in Windows with Python requires Visual C++ SDK as installed above. On Linux and Mac, the C++ libraries are installed with the compiler.
https://www.scivision.co/python-windows-visual-c++-14-required/
Following below command worked for me
[root#sandbox ~]# pip install google-api-python-client==1.6.4
Methods to solve setup.pu egg_info issue when updating setuptools or not other methods doesnot works.
If CONDA version of the library is available to install use conda instead of pip.
Clone the library repo and then try installation by pip install -e . or by python setup.py install
upgrading python's version did the work for me.
I have just encountered the same problem when trying to pip install -e . a new repo. I did not notice that the contents of setup.py haven't been saved properly and I was effectively running the command with an empty setup.py.
Hence you may experience the same error message if the setup.py of the target package is either empty or malformed.
I solved it on Centos 7 by using:
sudo yum install libcurl-devel

I want to use opencv under python 3 in Ubunto 14.04. I plan to use the PyCharm IDE to develop my program.
Inside PyCharm I choose, I set:
File/Settings/Project:HelloWorld/Project Interpreter/3.4.3(/usr/bin/python3.4)
Python 3.4.3 is the default version of python in Ubunto 14.04.
Then I try to add opencv-python package:
File/Settings/Project:HelloWorld/Project Interpreter/+ (where you add the package)
and the system gives me this error:
Executed command:
pip install opencv-python
Try to run this command from the system terminal. Make sure that you
use the correct version of 'pip' installed for your Python interpreter located at '/usr/bin/python3.4'.
DEPRECATION: --no-install, --no-download, --build, and --no-clean are deprecated. See https://github.com/pypa/pip/issues/906.
Downloading/unpacking opencv-python
Could not find any downloads that satisfy the requirement opencv-python
Cleaning up...
No distributions at all found for opencv-python
Storing debug log for failure in /root/.pip/pip.log
the error is the same when I run the command from terminal. I believe the problem is related to installing opencv under python3 but I am not sure I know if I can fix it. Please let me know your opinion.
Thanks
The fix is to update your pip and try again. This worked for me.
So, first:
pip install --upgrade pip
after that:
pip install opencv-python
First, you should not use install opencv-python, this is not the official opencv package.
Please, see:
**SOLVED** How to include libgtk2.0-dev and pkg-config in cmake when installing openCV on Ubuntu 16
If you want to install opencv, you can follow this website, that worked for me. You might need to apapt some parts (mainly version numbers, and paths during the cmake process).
I also faced similar issue in the windows and pip upgrade worked for me,
pip install --upgrade pip
and install using below command,
pip install opencv-python
As far as I can see from querying pip (using pip search opencv) there is no package called opencv-python I think the one you're looking for is pyopencv.
this issue appears to be almost identical
I'm attempting to make a website with a few others for the first time, and have run into a weird error when trying to use Django/Python/VirtualEnv. I've found solutions to this problem for other operating systems, such as Ubuntu, but can't find any good solutions for Mac.
This is the relevant code being run:
virtualenv -p python3 venv
source venv/bin/activate
pip install -r requirements.txt
After running that block, I get the following errors:
AssertionError
Failed building wheel for django-toolbelt
Running setup.py bdist_wheel for psycopg2
...
AssertionError
Failed building wheel for psycopg2
Failed to build django-toolbelt psycopg2
I believe I've installed the "django-toolbelt" and "psycopg2", so I'm not sure why it would be failing.
The only difference I can think of is that I did not use the command
sudo apt-get install libpq-dev
as was instructed for Ubuntu usage as I believe that installing postgresql with brew took care of the header.
Thanks for any help or insight!
For MacOS users
After trying all the above methods (which did not work for me on MacOS 10.14), that one worked :
Install openssl with brew install openssl if you don't have it already.
add openssl path to LIBRARY_PATH :
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/
install psycopg2 with pip pip3 install psycopg2
I had the same problem on Arch linux. I think that it's not an OS dependant problem. Anyway, I fixed this by finding the outdated packages and updating then.
pip uninstall psycopg2
pip list --outdated
pip install --upgrade wheel
pip install --upgrade setuptools
pip install psycopg2
I was also getting same error.
Using Python 3.7.3 and pip 19.1.1.
I used following command.
pip install psycopg2-binary==2.8.3
TDLR
If you aren't used to installing Python C-extensions, and psycopg2 isn't a core part of your work, try
pip install psycopg2-binary
Building Locally
psycopg2 is a C-extension, so it requires compilation when being installed by pip. The Build Prerequisites section of the docs explain what must be done to make installation via pip possible. In summary (for psycopg 2.8.5):
a C compiler must be installed on the machine
the Python header files must be installed
the libpq header files must be installed
the pg_config program must be installed (it usually comes with the libpq headers) and on $PATH.
With these prerequisites satisfied, pip install psycopg2 ought to succeed.
Installing pre-compiled wheels
Alternatively, pip can install pre-compiled binaries so that compilation (and the associated setup) is not required. They can be installed like this:
pip install psycopg2-binary
The docs note that
The psycopg2-binary package is meant for beginners to start playing with Python and PostgreSQL without the need to meet the build requirements.
but I would suggest that psycopg2-binary is often good enough for local development work if you are not using psycopg2 directly, but just as a dependency.
Concluding advice
Read the informative installation documentation, not only to overcome installation issues but also to understand the impact of using the pre-compiled binaries in some scenarios.
I had same problem and this appears to be a Mojave Issue, I was able to resolve with:
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
For Mac OS X users:
1. First check your postgresql path by running this command in terminal:
pg_config
If this fails lookup how to add pg_config to your path.
2. Next install Xcode Tools by running this command in terminal:
xcode-select --install
If you have both those sorted out now try to install psycopg2 again
For MacOS users, this question has the correct solution:
install command line tools if necessary:
xcode-select --install
then
env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip install psycopg2
I was also facing the same after running all the above commands, but the following two commands worked for me:
Instead of pip, use this:
sudo apt-get install libpq-dev
then run this command:
pip install psycopg2
On OS X, I was able to solve this by simply upgrading wheel before installing psycopg2:
pip install --upgrade wheel
For OSX Sierra users, it seems that an xcode update is the solution: Can't install psycopg2 package through pip install... Is this because of Sierra?
I tried all the above solutions but they did not work for me. What I did was change the psycopg2 version in my requirements.txt file from psycopg2==2.7.4 to psycopg2==2.7.6
Is your error message complete? the most encountered reason for failing to install psycopg2 on mac from pip is pg_config is not in path.
by the way, using macports or fink to install psycopg2 is more recommended way, so you don't have to worry about pg_config, libpq-dev and python-dev.
plus, are using Python 3.5? then upgrage your wheel to > 0.25.0 using pip.
I faced the same issue, but the answers above didn't work for me.
So this is what I did in my requirements.txt
psycopg2-binary==2.7.6.1 and it worked fine
I had this issue on several packages, including psycopg2, numpy, and pandas. I simply removed the version from the requirements.txt file, and it worked.
So instead of psycopg2-binary==2.7.6.1 I just had psycopg2-binary.
I know you are asking for development environment but if you are deploying on server say, Heroku. Just add below line in the requirements.txt of your project.
django-heroku==0.3.1
As this package itself will install the required packages like psycopg2 on server deployment.So let the server(heroku) should take care of it.
sudo apt install libpq-dev python3.X-dev
where X is the sub version,
these should be followed by :
pip install --upgrade wheel
pip install --upgrade setuptools
pip install psycopg2
Enjoy !!!
I solved my problem by updating/installing vs_BuildTools. The link to the software was given in the error itself.

I am trying to run Google's deep dream. For some odd reason I keep getting
ImportError: No module named google.protobuf
after trying to import protobuf. I have installed protobuf using sudo install protobuf. I am running python 2.7 OSX Yosemite 10.10.3.
I think it may be a deployment location issue but i cant find anything on the web about it. Currently deploying to /usr/local/lib/python2.7/site-packages.
There is another possibility, if you are running a python 2.7.11 or other similar versions,
sudo pip install protobuf
is ok.
But if you are in a anaconda environment, you should use
conda install protobuf
Locating the google directory in the site-packages directory (for the proper latter directory, of course) and manually creating an (empty) __init__.py resolved this issue for me.
(Note that within this directory is the protobuf directory but my installation of Python 2.7 did not accept the new-style packages so the __init__.py was required, even if empty, to identify the folder as a package folder.)
...In case this helps anyone in the future.
In my case I
downloaded the source code, compiled and installed:
$ ./configure
$ make
$ make check
$ sudo make install`
for python I located its folder(python) under source code, and ran commands:
$ python setup.py build
$ python setup.py install'
Not sure if this could help you..
I got the same error message when I tried to use Tensor Flow. The solution was simply to uninstall Tensor Flow and protobuf:
$ sudo pip uninstall protobuf
$ sudo pip uninstall tensorflow
And reinstall it again: pip installation of Tensorflow. Currently, this is:
# Ubuntu/Linux 64-bit, CPU only:
$ sudo pip install --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.8.0rc0-cp27-none-linux_x86_64.whl
# Ubuntu/Linux 64-bit, GPU enabled:
$ sudo pip install --upgrade https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.8.0rc0-cp27-none-linux_x86_64.whl
# Mac OS X, CPU only:
$ sudo easy_install --upgrade six
$ sudo pip install --upgrade https://storage.googleapis.com/tensorflow/mac/tensorflow-0.8.0rc0-py2-none-any.whl
when I command pip install protobuf, I get the error:
Cannot uninstall 'six'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
If you have the same problem as me, you should do the following commands.
pip install --ignore-installed six
sudo pip install protobuf
According to your comments, you have multiply versions of python
what could happend is that you install the package with pip of anthor python
pip is actually link to script that donwload and install your package.
two possible solutions:
go to $(PYTHONPATH)/Scripts and run pip from that folder that way you insure
you use the correct pip
create alias to pip which points to $(PYTHONPATH)/Scripts/pip and then run pip install
how will you know it worked?
Simple if the new pip is used the package will be install successfully, otherwise the package is already installed
I installed the protobuf with this command:
conda install -c anaconda protobuf=2.6.1
(you should check the version of protobuf)
In my case, MacOS has the permission control.
sudo -H pip3 install protobuf
I had this problem to when I had a google.py file in my project files.
It is quite easy to reproduce.
main.py: import tensorflow as tf
google.py: print("Protobuf error due to google.py")
Not sure if this is a bug and where to report it.
Python.
I've exhausted my research on this topic. I have it running on Windows just fine, but I can't figure out a way to install it on Linux.
How do I install it on Linux?
The installation guide is here. I installed it 10 Minutes ago on Ubuntu(13.10) using the following command:
sudo pip install SimpleGUICS2Pygame
It looks like an ordinary python package, so just:
pip install --user SimpleGUICS2Pygame
If that gives errors, post them.
The short answer is:
python -m pip install SimpleGUICS2Pygame --user --upgrade
Since the version 2 all requirements are automatically installed. But for that you need have Python tools up to date. All steps are described in the online documentation:
https://simpleguics2pygame.readthedocs.io/en/latest/#installation
I'm deploying a Django app to a dev server and am hitting this error when I run pip install -r requirements.txt:
Traceback (most recent call last):
File "/var/www/mydir/virtualenvs/dev/bin/pip", line 5, in <module>
from pkg_resources import load_entry_point
ImportError: No module named pkg_resources
pkg_resources appears to be distributed with setuptools. Initially I thought this might not be installed to the Python in the virtualenv, so I installed setuptools 2.6 (same version as Python) to the Python site-packages in the virtualenv with the following command:
sh setuptools-0.6c11-py2.6.egg --install-dir /var/www/mydir/virtualenvs/dev/lib/python2.6/site-packages
EDIT: This only happens inside the virtualenv. If I open a console outside the virtualenv then pkg_resources is present, but I am still getting the same error.
Any ideas as to why pkg_resources is not on the path?
July 2018 Update
Most people should now use pip install setuptools (possibly with sudo).
Some may need to (re)install the python-setuptools package via their package manager (apt-get install, yum install, etc.).
This issue can be highly dependent on your OS and dev environment. See the legacy/other answers below if the above isn't working for you.
Explanation
This error message is caused by a missing/broken Python setuptools package. Per Matt M.'s comment and setuptools issue #581, the bootstrap script referred to below is no longer the recommended installation method.
The bootstrap script instructions will remain below, in case it's still helpful to anyone.
Legacy Answer
I encountered the same ImportError today while trying to use pip. Somehow the setuptools package had been deleted in my Python environment.
To fix the issue, run the setup script for setuptools:
wget https://bootstrap.pypa.io/ez_setup.py -O - | python
(or if you don't have wget installed (e.g. OS X), try
curl https://bootstrap.pypa.io/ez_setup.py | python
possibly with sudo prepended.)
If you have any version of distribute, or any setuptools below 0.6, you will have to uninstall it first.*
See Installation Instructions for further details.
* If you already have a working distribute, upgrading it to the "compatibility wrapper" that switches you over to setuptools is easier. But if things are already broken, don't try that.
sudo apt-get install --reinstall python-pkg-resources
fixed it for me in Debian. Seems like uninstalling some .deb packages (twisted set in my case) has broken the path python uses to find packages
I have seen this error while trying to install rhodecode to a virtualenv on ubuntu 13.10. For me the solution was to run
pip install --upgrade setuptools
pip install --upgrade distribute
before I run easy_install rhodecode.
It also happened to me. I think the problem will happen if the requirements.txt contains a "distribute" entry while the virtualenv uses setuptools. Pip will try to patch setuptools to make room for distribute, but unfortunately it will fail half way.
The easy solution is delete your current virtualenv then make a new virtualenv with --distribute argument.
An example if using virtualenvwrapper:
$ deactivate
$ rmvirtualenv yourenv
$ mkvirtualenv yourenv --distribute
$ workon yourenv
$ pip install -r requirements.txt
In CentOS 6 installing the package python-setuptools fixed it.
yum install python-setuptools
After trying several of these answers, then reaching out to a colleague, what worked for me on Ubuntu 16.04 was:
pip install --force-reinstall -U setuptools
pip install --force-reinstall -U pip
In my case, it was only an old version of pillow 3.1.1 that was having trouble (pillow 4.x worked fine), and that's now resolved!
I had this error earlier and the highest rated answer gave me an error trying to download the ez_setup.py file. I found another source so you can run the command:
curl http://peak.telecommunity.com/dist/ez_setup.py | python
I found that I also had to use sudo to get it working, so you may need to run:
sudo curl http://peak.telecommunity.com/dist/ez_setup.py | sudo python
I've also created another location that the script can be downloaded from:
https://gist.github.com/ajtrichards/42e73562a89edb1039f3
Needed a little bit more sudo. Then used easy_install to install pip. Works.
sudo wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
sudo easy_install pip
I fixed the error with virtualenv by doing this:
Copied pkg_resources.py from
/Library/Python/2.7/site-packages/setuptools
to
/Library/Python/2.7/site-packages/
This may be a cheap workaround, but it worked for me.
.
If setup tools doesn't exist, you can try installing system-site-packages by typing virtualenv --system-site-packages /DESTINATION DIRECTORY, changing the last part to be the directory you want to install to. pkg_rousources.py will be under that directory in lib/python2.7/site-packages
the simple resoluition is that you can use conda to upgrade setuptools or entire enviroment. (Specially for windows user.)
conda upgrade -c anaconda setuptools
if the setuptools is removed, you need to install setuptools again.
conda install -c anaconda setuptools
if these all methodes doesn't work, you can upgrade conda environement. But I do not recommend that you need to reinstall and uninstall some packages because after that it will exacerbate the situation.
A lot of answers are recommending the following but if you read through the source of that script, you'll realise it's deprecated.
wget https://bootstrap.pypa.io/ez_setup.py -O - | python
If your pip is also broken, this won't work either.
pip install setuptools
I found I had to run the command from Ensure pip, setuptools, and wheel are up to date, to get pip working again.
python -m pip install --upgrade pip setuptools wheel
You can use the command
sudo apt-get install --reinstall python3-pkg-resources
if you are using python3 , this was the case with me.
I ran into this problem after installing the latest Python version 3.10.4.
Somehow, the setuptools package and pip were deleted.
I used the following command to resolve the issue :
in [Windows]
py -m ensurepip --default-pip
For me, this error was being caused because I had a subdirectory called "site"! I don't know if this is a pip bug or not, but I started with:
/some/dir/requirements.txt
/some/dir/site/
pip install -r requirements.txt wouldn't work, giving me the above error!
renaming the subfolder from "site" to "src" fixed the problem! Maybe pip is looking for "site-packages"? Crazy.
For me, it turned out to be a permissions problem on site-packages. Since it's only my dev environment, I raised the permissions and everything is working again:
sudo chmod -R a+rwx /path/to/my/venv/lib/python2.7/site-packages/
I had this problem when I had activated my virtualenv as a different user than the one who created it. It seems to be a permission problem. I discovered this when I tried the answer by #cwc and saw this in the output:
Installing easy_install script to /path/env/bin
error: /path/env/bin/easy_install: Permission denied
Switching back to the user that created the virtualenv, then running the original pip install command went without problems. Hope this helps!
I had this problem today as well. I only got the problem inside the virtual env.
The solution for me was deactivating the virtual env, deleting and then uninstalling virtualenv with pip and reinstalling it. After that I created a new virtual env for my project, then pip worked fine both inside the virtual environment as in the normal environment.
Looks like they have moved away from bitbucket and are now on github (https://github.com/pypa/setuptools)
Command to run is:
wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
If you are encountering this issue with an application installed via conda, the solution (as stated in this bug report) is simply to install setup-tools with:
conda install setuptools
On Windows, with python 3.7, this worked for me:
pip install --upgrade setuptools --user
--user installs packages in your home directory, which doesn't require admin privileges.
Apparently you're missing setuptools. Some virtualenv versions use distribute instead of setuptools by default. Use the --setuptools option when creating the virtualenv or set the VIRTUALENV_SETUPTOOLS=1 in your environment.
None of the posted answers worked for me, so I reinstalled pip and it worked!
sudo apt-get install python-setuptools python-dev build-essential
sudo easy_install pip
pip install --upgrade setuptools
(reference: http://www.saltycrane.com/blog/2010/02/how-install-pip-ubuntu/)
In my case, I had 2 python versions installed initially and later I had deleted the older one. So while creating the virtual environment
virtualenv venv
was referring to the uninstalled python
What worked for me
python3 -m virtualenv venv
Same is true when you are trying to use pip.
I came across this answer when I was trying to follow this guide for OSX. What worked for me was, after running python get-pip, I had to ALSO easy_install pip. That fixed the issue of not being able to run pip at all. I did have a bunch of old macport stuff installed. That may have conflicted.
On windows, I installed pip downloaded from www.lfd.uci.edu/~gohlke/pythonlibs/ then encontered this problem.
So I should have installed setuptools(easy_install) first.
just reinstall your setuptools by :
$ sudo wget https://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz#md5=7df2a529a074f613b509fb44feefefe74e
$ tar -zxvf setuptools-0.6c11.tar.gz
$ cd setuptools-0.6c11/
$ sudo python setup.py build
$ sudo python setup.py install
$ sudo pip install --upgrade setuptools
then everything will be fine.
I use CentOS 6.7, and my python was just upgrade from 2.6.6 to 2.7.11, after tried so many different answer, finally the following one does the job:
sudo yum install python-devel
Hope help someone in the same situation.
I ran into this problem after updating my Ubuntu build. It seems to have gone through and removed set up tools in all of my virtual environments.
To remedy this I reinstalled the virtual environment back into the target directory. This cleaned up missing setup tools and got things running again.
e.g.:
~/RepoDir/TestProject$ virtualenv TestEnvironmentDir
For me a good fix was to use --no-download option to virtualenv (VIRTUALENV_NO_DOWNLOAD=1 tox for tox.)
On Opensuse 42.1 the following fixed this issue:
