I want to install pytorch3d version 0.3.0 or above, but pip sees only 0.0.1 version for installing. I runned next commands:
pip install pytorch3d==0.3.0
And got the next error:
ERROR: Could not find a version that satisfies the requirement pytorch3d==0.3.0 (from versions: 0.0.1)
ERROR: No matching distribution found for pytorch3d==0.3.0
If I run the install command without a specific version, pip will install the package with version 0.0.1.
My environment:
Windows 10 x64
Python 3.9.7
pip 21.2.4
Note:
direct internet connection, no proxy used
I haven't others versions python on pc
same errors when installing next packages: torchvision==0.7.0, torch==1.6.0
I tried with the virtualenv and without them
I installed Python from the windows store.
From their installation guide and your requirements use:
pip install pytorch3d -f https://dl.fbaipublicfiles.com/pytorch3d/packaging/wheels/py38_cu102_pyt190/download.html
Specified package cannot be installed via pip, because not supported on my os(Windows 10). This can be seen on the page with the version and available files for download of the required package.
I've been trying to install flask-mysqldb using pip install flask-mysqldb, but every time I try it gives me an error that says :
error: command 'C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.14.26428\bin\HostX86\x86\cl.exe' failed with exit status 2
I've looked around a lot and no answer works for me. I searched the file in https://www.lfd.uci.edu/~gohlke/pythonlibs/ but its not there.
I am on Windows 7 x64.
Of course you can not find whl for flask-mysqldb, but you can find mysqlclient.
Download suitable version for you platform from https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysqlclient
Then, e.g. pip install mysqlclient-1.3.13-cp27-cp27m-win32.whl, depends what you download.
Finally, pip install flask-mysqldb again, this will work for you.
the same issue/problem I've also received,
That is flask_mysqldb 'no module'
first of all flask_mysqldb isn't installed through pip,
You have to install a suitable version for mysqlclient
for me it worked
I'm using window 10 having python3.8 installed....... to rectfiy the error use the follwing procedure:
click on the link
https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysqlclient and select mysqlclient‑1.4.6‑cp38‑cp38‑win32.whl (python3.8 a suitable version for me) download it
then search for the directory where downloaded ..... and then through command prompt type
pip install mysqlclient‑1.4.6‑cp38‑cp38‑win32.whl
and then
pip install flask_mysqldb
and done
I had the same problem
I was using python 3.8 and it's not supported by this package.
https://flask-mysqldb.readthedocs.io/en/latest/ : Flask-MySQLdb is compatible with and tested on Python 2.7, 3.5, 3.6 and 3.7
I recreated a virtual environment with python 3.7 and it all worked.
installing above must be made
For Windows
install pip install wheel
after go to on your browser ' https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python '
find the appropriate package for the python version and download.
and copy that file to C:\Users<your-computer-name> .
go to cmd again and write here pip install flask-mysqldb
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.

Fixed by installing python3.7-dev: sudo apt install python3.7-dev, based on the link.
Python: 3.7
Ubuntu: 20.04.3 LTS
I'm trying to install lxml for Centos6.3, due to this issue. It looks like I've got a conflicting version of pip. The standing solution seems to re-install pip for the correct version of python.
My main issue is that all the methods I've found for installing pip require an internet connection. Is it possible to download pip install files, and then run pip install -U pip and point it at the right files?
The PyPI page for pip only has pip6.11 as a .whl. I've tried running pip install -U pip-6.1.1-py2.py3-none-any.whl and it's not worked.
I'm stumped. How do I install it?
You could try to download pip and setuptools manually from: https://pypi.org/project/pip/#files and https://pypi.org/project/setuptools/#files
get the python pip script from: https://bootstrap.pypa.io/get-pip.py
after that unzip/untar packages and run:
python get-pip.py --no-index --find-links=/path/to/pip-and-setuptools
or alternatively trying:
python setup.py install when running in unpacked folders

Any idea what might be going wrong?
Pyenv is a python version management tool, something like rbenv but for python.
You could easily install and change python version via pyenv easily.
The following shows how to install python with version 2.7.8 through pyenv:
ubuntu#ubuntu:~$ pyenv install 2.7.8
Downloading Python-2.7.8.tgz...
-> http://yyuu.github.io/pythons/74d70b914da4487aa1d97222b29e9554d042f825f26cb2b93abd20fdda56b557
Installing Python-2.7.8...
Installing setuptools from https://bootstrap.pypa.io/ez_setup.py...
Installing pip from https://bootstrap.pypa.io/get-pip.py...
Installed Python-2.7.8 to /home/ubuntu/.pyenv/versions/2.7.8
as you can see, its very simple.
The command pyenv install "version" help you to install a specific versions of python easily and even pip, setuptools are also automatically installed.
I suggest giving pyenv a try!!
