Python3 Virtual Environment Support

[arocks]

Hi, I use Arch Linux which has standardized on Python 3. Since python 3 has a different virtual environment system pyvenv built-in; can you suggest how we can point elpy to use this environment?

Thanks!

elpy uses pvenv.el to manage venvs. It has pyvenv-activate function to activate venv.

So, You can do

M-x pyvenv-activate RET /path/to/your/venv/ RET

to activate required env.

If you are using projectile, You can use projectile-switch-project-hook to auto activate venv on switching project.

Yes, I did try pyvenv-activate and it returned a post activation error. It seems like mkvirtualenv wrapper is assumed to be installed.

For the record I solved the problem by doing a system wide install. But I would like to know if there is support for pyvenv.

Thank you for the report and sorry for not responding earlier, I was on vacation.

This is indeed a bug – pyvenv should not fail if virtualenvwrapper is not installed.

Closing this issue as it is a problem in pyvenv. See jorgenschaefer/pyvenv#24 for an issue to track this bug.
