Issue when pip installing packages

Question

Please see my previous question here. I have spent all day searching on what my issues are and still running into pip install issues. This time my error message is a little different. What I have done since my previous post:

Made sure that C:\mysys64\mingw64\bin was added to my path under system environment variables
edit the c_cpp_properties.json specifically the "intelliSenseMode" in VSCode from "windows-msvc-x64" to "windows-gcc-x64"
re-check my Python.h file under directory C:\msys64\mingw64\include\python3.9\Python.h to make sure the errors were gone by the #include <unistd.h> which they were.
Retry pip install Flask-SQLAlchemy and now I get the following errors...

Terminal window output

However there is no longer a squiggly error line under #include <unistd.h> in my Python.h file. Mind you I have no clue what I am doing in trying to fix this. Please let me know if there is a solution.

Update 2022.02.01: I have unistalled version 3.9.7 of python and installed version 3.10.2. I have updated pip to version 22.02.2 and have tried the solutions given below. After downloading the wheels greenlet‑1.1.2‑cp310‑cp310‑win32.whl and greenlet‑1.1.2‑cp310‑cp310‑win_amd64.whl I went to my downloads folder and ran the commands and follows:

C:\Users\t\Downloads>C:\msys64\mingw64\bin\python.exe -m pip install greenlet-1.1.2-cp310-cp310-win_amd64.whl
ERROR: greenlet-1.1.2-cp310-cp310-win_amd64.whl is not a supported wheel on this platform.

ERROR: greenlet-1.1.2-cp310-cp310-win32.whl is not a supported wheel on this platform.

After that didnt work I tried to pip install greenlet directly with pip install greenlet and got the following output:

  Building wheel for greenlet (setup.py) ... error
  error: subprocess-exited-with-error

  × python setup.py bdist_wheel did not run successfully.

and further down

  note: This error originates from a subprocess, and is likely not a problem with pip.

FWIW, why not show us your errors when you **only** `pip install SQLAlchemy`? The rest, Jinja, Flask, etc... is just adding noise. — JL Peyret, Jan 17 '22 at 17:43
You may have to tweak your pip install command, for SQLAlchemy only, with the `-I` and `-L` flags. For example, for Pygraphviz, the documentation gave an [example](https://pygraphviz.github.io/documentation/stable/install.html#windows). You may need to try a few times, I had to point *above* where I originally thought. — JL Peyret, Jan 17 '22 at 18:12
yes sorry I figured since I am no expert, showing more might be better. and I wasted time updating Visual Studio and not VSCode...anyway here is where I am at. I followed [this](https://packaging.python.org/en/latest/tutorials/installing-packages/) guide. I ran `-m pip install --upgrade pip setuptools wheel` and got this `WARNING: The script wheel.exe is installed in 'C:\Users\t\AppData\Roaming\Python\Python39\Scripts' which is not on PATH. Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.` — Duke3e33, Jan 17 '22 at 19:24
And this `WARNING: The scripts pip.exe, pip3.9.exe and pip3.exe are installed in 'C:\Users\t\AppData\Roaming\Python\Python39\Scripts' which is not on PATH.` Not sure if that could be an issue? I then ran `py -m pip install SQLAlchemy` command and got `Installing collected packages: greenlet, SQLAlchemy Successfully installed SQLAlchemy-1.4.29 greenlet-1.1.2` but when I ran `pip list` command neither package was listed... I am at a loss — Duke3e33, Jan 17 '22 at 19:26

Following commands solved the issue on my m1 Mac -

- brew install graphviz
- python3 -m pip install \           
    --global-option=build_ext \
    --global-option="-I$(brew --prefix graphviz)/include/" \
    --global-option="-L$(brew --prefix graphviz)/lib/" \
    pygraphviz

You can simply download an appropriate whl file from here and install it.

For you greenlet‑1.1.2‑cp39‑cp39‑win_amd64.whl should be correct. After downloading, cd to your download directory and run

C:\msys64\mingw64\bin\python.exe -m pip install greenlet‑1.1.2‑cp39‑cp39‑win_amd64.whl

Then try your original installation again.

Note

There is also a whl file for Flask_SQLAlchemy‑2.5.1‑py3‑none‑any.whl available on the same website. You could also download and install that

Hi, I get the following error when running the command from my downloads `C:\Users\t\Downloads>C:\msys64\mingw64\bin\python.exe -m pip install greenlet-1.1.2-cp39-cp39-win_amd64.whl ERROR: greenlet-1.1.2-cp39-cp39-win_amd64.whl is not a supported wheel on this platform.` – Duke3e33 Jan 17 '22 at 16:53

The pip in the py -m pip is different from the pip in the pip list. You can through py -m pip --version and pip --version to get the pip locations.

I can install the greenlet package successfully through:

pip install greenlet --no-cache-dir

I am using python310, It looks like have some problems with python39. If it does not work, as @FlyingTeller has suggested, you can download it manually.

As you described greenlet-1.1.2-cp39-cp39-win_amd64.whl does not work, so have you tried greenlet‑1.1.2‑cp39‑cp39‑win32.whl?

>>> import platform
>>> platform.architecture()

You can get architecture through the above codes.

I also got the same error with `win32` wheel. `C:\msys64\mingw64\bin\python.exe -m pip install greenlet-1.1.2-cp39-cp39-win32.whl ERROR: greenlet-1.1.2-cp39-cp39-win32.whl is not a supported wheel on this platform.` – Duke3e33 Jan 18 '22 at 09:48
to download manually are you suggesting I get it from the source file type from [here](https://pypi.org/project/greenlet/#files)? – Duke3e33 Jan 18 '22 at 09:51
@Duke3e33 Sorry for being late, what's the result of the `platform.architecture()`? – Steven-MSFT Jan 19 '22 at 01:51
Is this the information you are looking for? After running that command this is the output `>>> import platform >>> platform.architecture() ('64bit', 'WindowsPE') >>>` – Duke3e33 Jan 19 '22 at 15:33
@msys64 Sorry, but could you try to install a normal python? instead of which related to msys64? – Steven-MSFT Jan 20 '22 at 02:10
Sorry @steven-MSFT is there anyway you could be more specific as I am still no expert on this. What do you mean install a normal python? – Duke3e33 Jan 20 '22 at 15:00
can we revisit this? I have downloaded python 3.10.2 and tried to pip install again and still have issues, however with the newer version of pip, I have gotten some more information on my error message. Please see update – Duke3e33 Feb 01 '22 at 15:22

I updated pip, setuptools and wheel and it it solved the problem.

pip install --upgrade pip
pip install --upgrade setuptools wheel

note: if your pip is aliased as pip3 (Python 3) use pip3 instead of pip

 pip3 install --upgrade pip
 pip3 install --upgrade setuptools wheel

refer to this link for more information: https://bobbyhadz.com/blog/python-error-legacy-install-failure

I had issues to install greenlet 2.0.1 in PyCharm on Mac M1.

I've upgraded:

pip install --upgrade pip

pip install --upgrade setuptools wheel

And thanks to @joydeba comment - I've installed Homebrew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

*Follow the instructions at the end of installation

After these steps I was able to install greenlet in PyCharm with no problem!
