Whenever I install my python project using 'python setup.py install', and invoke my project on a CentOS vagrant box, it works great. The dependencies get resolved perfectly.
However, if I create an rpm using fpm for my project, install the rpm using 'rpm -i rpm-file.rpm', manually install the dependencies using 'pip install -r requirements-file-path.txt' and then invoke my project on another CentOS vagrant box, I get the following error:
File "/usr/bin/<name-of-my-project>", line 5, in <module>
from pkg_resources import load_entry_point
File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 2655, in <module>

File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 546, in resolve
raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: fabric==1.10.2
Uninstalling the dependencies using 'pip uninstall' and reinstalling them doesn't fix the problem. What am I missing?
Just found the answer on the Fabric FAQ page: http://www.fabfile.org/faq.html/. Executing:
sudo pip install -U setuptools
Then re-installing the dependencies and project solved my problem. But welcome to other answers.

Hi I'm a beginner of python, I don't remember when and how I installed python3.8 on my Macbook air, only knew the installed path:
% which python
/usr/bin/python
% which python3
/usr/local/bin/python3
The pip command cannot not be found but pip3 is ok. Today I want to install virtaulenv:
% sudo -H pip3 install virtualenv
WARNING: Ignoring invalid distribution - (/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages)
Successfully installed virtualenv-20.6.0
I can use "pip3 show virtualenv" to know the info:
% pip3 show virtualenv
Name: virtualenv
Version: 20.6.0
Summary: Virtual Python Environment builder

But when I use "virtualenv" I got command not found message then I "pip3 uninstall" it. I searched for this and got a tip to use "easy_install" to install virtualenv. After installed I can execute the command, but got some error message:

It seems doesn't work and I try the "sudo pip3 uninstall virtualenv" to uninstall it successfully, but it seems not really be removed:
% which virtualenv
/usr/local/bin/virtualenv
I have no idea about this, could you help me? I just want to run virtualenv normally and create flask project ...
PS. I can "sudo pip3 install flask" and "pip3 show flask" but still cannot run flask cammand (command not found), what should I do?
Thanks a lot!
try being explicit in the version of python you are using and install using -m pip instead
python3 -m pip install virtualenv
python3 -m virtualenv venv # create a new venv in ./venv
source ./venv/bin/activate # activate your new venv
often times the pip/pip3 just isnt pointing at the same python version you think you are using... by using this technique you are sure to be using the correct python and pip
I have downloaded, built and installed the sample pypi project. The project is supposed to be used to give an insight to python packaging and is referenced in Python Packaging User Guide and Packaging and Distributing Projects. I am therefore confused to why on earth following their instructions on creating the package I have an error when uninstalling it.
As mentioned above I have used their sample project. If anyone can shed some light it would be appreciated.
Key notes: I am running Mac OSX, my installed python version is 3.5.1
Below are steps to reproduce the problem:
mkdir testdirectory
cd testdirectory/
pyvenv venv # Creating a virtual environment
source venv/bin/activate
git clone https://github.com/pypa/sampleproject.git # Getting sample project
cd sampleproject/
python setup.py build
python setup.py install # Installing on the virtual environment
pip list
peppercorn (0.5)
pip (7.1.2)
sample (1.2.0)
setuptools (18.2)
pip uninstall sample
Resulting in the following output:
Uninstalling sample-1.2.0:
/Users/steve/testdirectory/venv/bin/sample

It appears that the package has uninstalled correctly however the error is still thrown.
This is documented:
$ pip help uninstall
Usage:
pip uninstall [options] <package> ...
pip uninstall [options] -r <requirements file> ...
Description:
Uninstall packages.
pip is able to uninstall most installed packages. Known exceptions are:
- Pure distutils packages installed with ``python setup.py install``, which
leave behind no metadata to determine what files were installed.
- Script wrappers installed by ``python setup.py develop``.
i.e. you are getting the error because you didn't use pip itself to install - you used setup.py and so pip doesn't know what was installed.
Install package not with python setup.py install but with pip install .
Then uninstalling will work without errors
Have tried many things, but keep getting this error after multiple attempts to update python, pip, etc. I am on OS X running 10.9.5.

I was experiencing a similar error when trying to run eb, though not for dateutil...

For me the solution was to update setuptools:
sudo pip install --upgrade setuptools
Hope that helps somebody.
Use the following command:
pip install awsebcli
It will automatically upgrade all dependecies of awsebcli.
use the following command
sudo pip install python-dateutil
to upgrade it
Pip is probably linked to a different version of python then standard.
You should try installing pip using
python get-pip.py
(You can download get-pip.py from the pip website)
Otherwise, You can see which Python everything is linked too.
which python
head -1 $(which eb)
head -1 $(which pip)
You can change to shebang line in the eb script to match pip and it should all work.
You can also install using a virtualenv (pythons recommended way of installing)
virtualenv ~/ebenv
source ~/ebenv/bin/activate
pip install awsebcli
deactivate
sudo ln -s ~/ebenv/bin/eb /usr/local/bin/
in my case on mac osx 10.10, I had to reinstall.
sudo pip install python-dateutil
Just in case some runs into this type of error. check the last paragraph in the trace for the kind of error that it is being raised. In my case, this was:
raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.ContextualVersionConflict: (six 1.4.1
(/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python),
Requirement.parse('six>=1.5'), set(['python-dateutil']))
I had the exact same issue, for me, the eb script was using the wrong python. To solve it I just modified the eb script:
> which eb
/usr/local/bin/eb
> sudo vim /usr/local/bin/eb
## Change the first line from '#!/usr/bin/python' to '#!/usr/local/bin/python'
After restarting the terminal, everything work as expected.
From the raised error in your log, it needs python-dateutil>=2.1.
So you need to make sure that version is installed and install it if not. I had similar issue, and the solution (in my case) is:
$ pip install --ignore-installed python-dateutil==2.2

It seems that for some reason virtualenv is not putting everything it should be putting into the venv/bin folder. Right now, only python and two aliases, python2 and python2.7 are in there.
Thanks!
I believe this is caused by a bug in older versions of virtualenv and/or pip. It looks like you're using virtualenv 1.8.4 and pip 1.2.1. Is it possible for you to upgrade to latest virtualenv and pip (currently virtualenv 1.9.1 and pip 1.3.1)?
This should do it, if you have install privileges:
pip install pip --upgrade
pip install virtualenv --upgrade
At that point running the same command (i.e. sudo virtualenv venv --distribute) should give you what you want.
Easy_install and Pip doesn't work anymore on python 2.7, when I try to do:
sudo easy_install pip
I get:

I've already install both of them (and yes, first deleted them), but no result...
Thanks!

I had this issue where python's distribute package wasn't installed for some reason. After following the instructions on python-distribute, i got it working.
install the distribute package as follows:
$ wget https://web.archive.org/web/20100225231201/http://python-distribute.org/distribute_setup.py
$ python distribute_setup.py
EDIT: http://python-distribute.org/distribute_setup.py no longer works:
hopefully this will resolve your problem with running
$ sudo easy_install
Happy Coding!
If you installed a new version of easy_install through Distribute, the new command may have been installed in another directory, most likely /usr/local/bin/. But the traceback shows you were using /usr/bin/easy_install. Try this:
sudo /usr/local/bin/easy_install ...
Try
sudo easy_install Distribute
and if that exists, but is too old
sudo easy_install -U Distribute
Looks like either Distribute/setuptools (it's old name) is messed up or Python package settings. If either of these do not help, try removing the full Python 2.7 installation and reinstall everything from the scratch.
Possible reasons for the mess is that you have used both sudo easy_install / sudo pip and Linux distribution packages to mix and match system-wide installation packages. You should use virtualenv instead if you use pip/easy_install (no sudo needed)
http://pypi.python.org/pypi/virtualenv
I had a similar problem, but things were working fine as root. In my case, I found that the permissions on the python packages were not readable by the ID I was running the command under.
To correct it, I ran the following command to open the permission for read and execute to all users:
sudo chmod o+rx -R /usr/local/lib/python2.7/dist-packages/*.egg
I had similar issue when trying to install package via pip with python 3.6 on windows. (pip is supposed to work out of the box with this install)
The problem was not running as administrator.
Running cmd as administrator and then installing my package worked:
python -m pip install pylint
I was trying to get pip to work on the 2.7.0 version, but it seems like it doesn't come with the easy_install/pip files (Script folder in main directory), installing 2.7.13 solved the problem for me.
