Unknown command or script: "pip"

Trying to set up wenv on Fedora 39, wine 9.1.

Installation seems to run well:

$ WENV_PYTHONVERSION=3.12.4 wenv init
wine: configuration in L"/home/<user>/.local/share/wenv/win32" has been updated.

But trying to execute a pip command yields:

wenv pip list
Unknown command or script: "pip"

How could this be fixed?

[Openuser87]

Seems that happens with any version, except for default version 3.7. Also python command itself is not found:

wenv python --version
Unknown command or script: "python"

With default version, wenv init shows an error:

ERROR: This script does not work on Python 3.7. The minimum supported Python version is 3.8. Please use https://bootstrap.pypa.io/pip/3.7/get-pip.py instead.

Nevertheless, after that, python command seems to work:

wenv python --version
Python 3.7.4

But pip does not:

wenv pip list
Unknown command or script: "pip"

If you're setting an option via an environment variable the way you do it, every subsequent command must be prefixed with mentioned environment variable, e.g. WENV_PYTHONVERSION=3.12.4 wenv pip install foo. Alternatively, you can of cause alter this option also via configuration files etc.

[Openuser87]

Thank you, that works!

Ways to persist:

• exporting environment variable (e.g. something like export WENV_PYTHONVERSION=3.12.4)
• config (see example here), e.g. put the following into .wenv.json in the directory where you execute wenv:

  {
    "pythonversion": "3.12.4"
  }
  

Could this possibly be emphasized a little more in the official documentation?

[s-m-e]

Sure, this can be done.

Ran into this as well; only in my case the default wenv init came up with the error message (without any ENV variables set):

By default this seems to pull Python 3.7.0 which seems to no longer be supported (by pip?)

Affirmative. The default Python version for Python on Wine is outdated. Try 3.8 (e.g. 3.8.10) or younger instead.
