Please add to the list of installable Python interpreters :-)
Thanks!

This seems to be somewhat difficult - I'm getting errors:

Added support for it in master, thanks for the heads up! The problem you get seems to be something about pip, here is a workaround: https://gist.github.com/skyl/ea2ab1c62a547e381411

Thanks for the pointer to the workaround.
Seems like my Ubuntu install of pip isn't compatible with all versions of Python anymore (if it ever was). I'm starting to wonder whether pythonz shouldn't install its own version of pip and virtualenv/pyvenv etc.
Oh right... actually there is an incompatibility with virtualenv already, your instructions say mkvirtualenv and I need to use virtualenv (maybe the Ubuntu guys renamed the script, dunno what's up with that).
I guess that's serious work; should I open a new issue for that? Or is it a bad idea anyway?

I created pythonz as a fork of pythobbrew with 2 ideas: make is simpler/smaller, and add support for pythons other than CPython. This would break my first rule, which was to keep managing virtualenvs up to the user, since everyone has its own preferences.

mkvirtualenv is part of virtualenvwrapper, you'll need to install that one.

As I mentioned, that's not something I want for pythonz, sorry. One thing you can probably do is create a virtualenv with your system Python, update pip inside it, and use that one to install stuff with pythonz. I haven't tried it myself, but that might do it.

Hmm... seems the workaround doesn't work actually, and the jpythontools stuff is beyond my current understanding (lack of time to learn it all, unfortunately).
I guess I'll give up for now.
