PyCharm, Arch linux & Python 3.6

Love Python. Love PyCharm. Love Arch Linux.

Unfortunately Arch sneakily updated Python to 3.6. Cool, new version … but hey, why don’t my debug runs in PyCharm work any more??

ImportError: libpython3.5m.so.1.0: cannot open shared object file: No such file or directory

Yup, pretty confusing. It seems unable to find shared python 3.5 library. Well. After some cursing, turns out the solution is pretty simple (if you know what to do):

  • get pyenv
  • use pyenv to install Python 3.5.2, but with –enable-shared option set
  • use this python version for PyCharm projects (it does not matter if it’s in a virtualenv or not)

Like this:

$ PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 3.5.2
[...]
$ sudo $HOME/.pyenv/versions/3.5.2/bin/python "/opt/pycharm-professional/helpers/pydev/setup_cython.py" build_ext --inplace
[...]
$ _

That solved it for me 🙂
