pyCharm installed w/o errors (on Linux Mint) and the initial session (config etc.) was error-free. However subsequent calls to pycharm.sh result in the following error:
Traceback (most recent call last):
File "/usr/lib/python2.7/site.py", line 68, in <module>
File "/usr/lib/python2.7/os.py", line 398, in <module>

from abc import ABCMeta, abstractmethod
File "/usr/lib/python2.7/abc.py", line 8, in <module>
from _weakrefset import WeakSet
ImportError: No module named _weakrefset
My system is up-to-date and python-virtualenv is installed.
Can anyone give me a tip how to resolve this error?
