How to use my project's virtualenv?

[Cheukyin]

Jedi by default uses the virtualenv in .emacs/
But what should I do if I want to use the virtualenv of my project instead of the default one?

You can do it by setting jedi:environment-root or python-environment-directory.

Please see those docstrings

• https://github.com/tkf/emacs-jedi/blob/master/jedi.el#L1196
• https://github.com/tkf/emacs-python-environment/blob/master/python-environment.el#L39

Setting the variables mentioned above needs to write in my configuration file.

It takes a lot of trouble. Because I have several virtualenvs for each project.

Is there a convenient way to switch the virtualenv on the fly?

How about pyvenv.el or virtualenvwrapper.el ?

• https://github.com/porterjamesj/virtualenvwrapper.el

Sorry I don't know python programming well.

[Cheukyin]

I still have no idea how to implement it

But I seem to have grasped something after reading the docs of virtualenvwrapper

Maybe I should begin to learn some basic elisp
then I can read the source code ,
and know how to make the plugins work together

Thanks anyway

OK, I find a solution

Use the virtualenvwrapper.el and M-x pyvenv-workon to switch the virtualenv,
then jedi:stop-server to restart jedi.

It works!

@Cheukyin
Can you show your configuration for jedi? I faced with the same problem as you - #178
activating venv -> stopping jedi server (even killing it through kill -9) did not help jedi to recognize site packages from my project's venv.
