Activation / Deactivation of virtualenvs works only once

[nopper]

I have a project in which I created a .python-version file. In this case I have something like:

$ cat project/.python-version
project-2.7.8

Whenever I change my directory to the project root pyenv-virtualenv is invoked correctly. When I leave the virtual env is deactivated.

$ cd project
pyenv-virtualenv: activate project-2.7.8
(project-2.7.8) $ cd ..
pyenv-virtualenv: deactivate project-2.7.8

The problem is that if I re-enter in the project/ directory is not activated anymore.

$ cd project
# Nothing happens
$

It doesn't matter how many times I try, the activation seems to work only once. Successive attempts seem to ignore the virtualenv indicated in the .python-version file.

The pyenv virtualenv-init persists the state in environment variables of PYENV_ACTIVATE and PYENV_DEACTIVATE. If you have problem with activating virtualenv, please restart your shell or unset those environment variables.

Surely restarting the shell or unsetting the env variables solves the problem. But what I was expecting i a consistent activation / deactivation mechanism.

What I suggest is to unset the PYENV_DEACTIVATE whenever a deactivation is triggered in an automatic fashion without requiring the user to do so. This apparently solves the issue for me.

Could you consider such addition?

The current behaviour must not be expected for most users. I think this is a kind of bug of current impl.

As you mentioned, PYENV_DEACTIVATED should not persist after automatically triggered deactivation. I'll try to fix it in #47.

Ok closing this and following #47
