Insider install problem (Win 11)

[tamasgt]

Hello,

something changed, everything was working, I tried to update the Material MkDocs Insider and got the following error:

I tried updating python, pip, setuptools, but no matter what I do, it doesn't work. I tried the latest version of Python (3.12.3), now it's 3.11.9, but I can't install it. I tried:

pip        23.2.1
setuptools 65.5.0

or now with the last version

pip        24.1.1
setuptools 70.2.0

always the same error.
I cannot install either MkDocs free

pip install mkdocs-material

or insider

pip install --git+https://TOKEN@github.com/squidfunk/mkdocs-material-insiders.git@9.5.28-insiders-4.53.11

in an empty python virtual environment. Always the same error. The regex throws the first error.

Any idea what the problem might be?

Thanks,
Tamas

Hello @tamasgt,
the installation works for me on my normal Python 3.12 Windows 10 installation from python.org via the exe installer:

$ python -VV
Python 3.12.4 (tags/v3.12.4:8e8a4ba, Jun  6 2024, 19:30:16) [MSC v.1940 64 bit (AMD64)]

most likely, as the wheels for the regex module etc. are present for Windows and are compatible with my version.
https://pypi.org/project/regex/#files

However, when I try to run the install via MSYS2 and the mingw Python 3.11 I get the same crash:

$ python -VV
Python 3.11.9 (main, Apr 12 2024, 09:55:31)  [GCC 13.2.0 64 bit (AMD64)]
$ pip install mkdocs-material

      running build_ext
      error: [WinError 2] The system cannot find the file specified
      [end of output]

I'm drawing a blank for now, I will have to investigate the build process.

cc @vedranmiletic @alexvoss Since you were the main contributors in #7163

OK, all I had to do was to install GCC in MSYS2 @tamasgt and the installation worked fine after that:

pacman -S mingw-w64-x86_64-gcc

I didn't actually get to the full traceback of the subprocess, just read over the regex setup.py and saw .c files in the extension modules, and the build crashed on the build_ext step...

Sorry for the mention guys 🫡

Thanks for the reply. I found the solution.

The problem was caused by the fact that MSYS2 in documentation was installed (I installed it a long time ago.) and therefore the virtual environment is created differently by python. The solution was:

1. Uninstall MSYS2.
2. Uninstall Python
3. Delete directory C:\Users\USERNAME\AppData\Local\Programs\Python\PythonVERSION
4. Delete python virtual environment.
5. Install Python
6. Create python virtual environment.

and it works with latest Python version.
I will look at what you wrote #7163 and add if there is anything new. I'm still using this for now:

Hmm, you just uninstalled MSYS2 and installed the normal Python via the installer from python.org, right?
Based on your steps you didn't reinstall MSYS2, I actually found the solution for the error 😁
Good that you got it working anyways 👍

We should probably document the GCC requirement.

We should probably document the GCC requirement.

Perhaps we should, but in general the Getting Started uses GCC as an example in step 6:

• https://www.msys2.org/

So I think the documentation here should be related to an error like the one above, where the wheel build fails, because of a lacking file.
subprocess-exited-with-error
error: [WinError 2] The system cannot find the file specified
etc.

When I worked on the documentation I was under the impression that GCC was getting installed by default. It seems sensible to me to add it to the list of things to install here rather than relying on the MSYS documentation. Need to fire up a VM to go and check it out tomorrow.
