Pythonfinder should support the windows `py` command

Open taronaldinho opened this issue 2 years ago • 4 comments

Since upgrading pipenv to v2023.5.19, it does not successfully recognize the version of Python installed on my PC. It fails as follows.

PS > py -m pipenv --python 3.9
Warning: Python 3.9 was not found on your system...
Neither 'pyenv' nor 'asdf' could be found to install Python.
You can specify specific versions of Python with:
$ pipenv --python path\to\python

The path to each version of Python installed on the PC can be found from the py command. (I have not added the Python PATH according to the default installer settings.)

PS > py --list-paths
 -V:3.11 *        [USERPROFILE]\AppData\Local\Programs\Python\Python311\python.exe
 -V:3.10          [USERPROFILE]\AppData\Local\Programs\Python\Python310\python.exe
 -V:3.9           [USERPROFILE]\AppData\Local\Programs\Python\Python39\python.exe
 -V:3.8           [USERPROFILE]\AppData\Local\Programs\Python\Python38\python.exe
 -V:3.7           [USERPROFILE]\AppData\Local\Programs\Python\Python37\python.exe

Therefore, as indicated in the error message, the virtual environment can be successfully created by specifying the Python path to be used.

> py -m pipenv --python [USERPROFILE]\AppData\Local\Programs\Python\Python39\python.exe
-> It's OK.

However, by simply downgrading pipenv to v2023.4.29, the above command succeeds as before.

PS > py -m pip install -U pipenv==2023.4.29

...

Successfully installed pipenv-2023.4.29

PS > py -m pipenv --python 3.9

The same problem occurred on three PCs (Windows 10 and 11). Are there any steps that should be changed to enable the creation of virtual environments with py -m pipenv --python commands without specifying the full path of Python?

This is the first I've learned of the py command, and unfortunately it was not in our documentation that this was ever supported. I welcome to pythonfinder PRs that could support this, but what probably happened is in the refactor to pythonfinder -> pydantic, I encountered that we were using a completely different library to find Windows pythons which was creating problems with trying to have consistent code paths that we maintain and can fix windows bugs in. So now all operating systems use the same pythonfinder code paths that we maintain so it should be possible to support this again in the future.

@matteius Thank you for commenting on my problem. It would be great if the py command was supported again.

I've labeled it as something that will be considered for PR improvements, but myself and the other maintainer have limited bandwidth at present to make all of these improvements ourselves.

I believe I added sufficient support in: https://github.com/pypa/pipenv/pull/6360 however it could use testing specifically of the py command.
