PyCharm & Pyenv local?

Question

After I broke my Ubuntu precise with a Cython compilation I like to keep the system Python clean. I like to have 2.7.x & 3.4.x besides each other and used Pyenv to have a global default interpreter independent from the system python. Now I also want to define local interpreters on a per project basis, usually done with pyenv local. Unfortunately my favorite IDE PyCharm does only support pyenv global, the local .python-version files are obviously not recognized by PyCharm.

So I tried to use the pyenv global interpreter in PyCharm with ~/.pyenv/bin/python-local-exec which works but unfortunately is already deprecated. When I then tried to create a virtualenv from the pyenv Python 3 global interpreter, it throwed the follwing error:

The following command was executed:

virtualenv.py /home/barrios/code/so/venv

The error output of the command:

pyenv: `python-local-exec' is deprecated and will be removed in the next release.

ERROR: It thinks sys.prefix is '/home/barrios/.pyenv/bin' (should be '/home/barrios/code/so/venv')

As mentioned before, I don't want to install Python 3 into my Ubuntu system folders. Any ideas how to achieve that?

TNX a lot!

I'd suggest to use https://github.com/yyuu/pyenv-virtualenv to create virtualenv for a desired interpreter and then add it as a Python interpreter in PyCharm.
