Support pyenv-win on Windows

[empz]

Currently, the Python extension seems to rely on the py launcher installed by the official windows installers.

I'm using pyenv-win to manage different python versions on my Windows machine and I wasn't able to make VS Code detect it, even though running python on my terminal worked perfectly. I've even tried setting explicitly the python.defaultInterpreterPath setting but that didn't work either.

So, apart from the feature request. Is there a way to use the Python extension without having the py launcher available on C:\Windows

Thank you for the suggestion! We have marked this issue as "needs decision" to make sure we have a conversation about your idea. We plan to leave this feature request open for at least a month to see how many 👍 votes the opening comment gets to help us make our decision.

I'd love to have this feature too. Meanwhile I created a separate extension for pyenv-win to have a quick working solution for me. But would be awesome to see this feature work in this package of course. https://github.com/vgibilmanno/vscode-winpyenv

@vgibilmanno We have a experimental discovery component that supports this. Add this to your user settings to try it out:

    "python.experiments.optInto": [
        "pythonDiscoveryModule"
    ], 

And reload VS Code.
