I'm testing virtual environenment. So I create a new project (without inheriting global site packages). I can see that listing stuff etc... shows nothing is inherited from global packages. I can install a local/virtual package in that project (say numpy) and that works fine. I install something locally - say sklearn. I list again and I see that my new package is install in that environment. If I step back and pip3 --list on my SYSTEM's pip3, then I see that sklearn is not available. So I can see that my virtual env is actually contain to my project, as expected.
Then I create another project, everything the same BUT I selected "inherit global site packages". I again list everything that I have access to (with sys.getsitepackages()) and I see that my system's packages are all there. As expected up to now.
However, if I go to settings in that project & try to install a package with Pycharm I get an error:
Error: Traceback (most recent call last):
File "/opt/pycharm-community-2018.3.5/helpers/packaging_tool.py", line 73, in run_pip

from pip._vendor.retrying import retry
ModuleNotFoundError: No module named 'pip._vendor.retrying'
It then suggests me to try to install the package with the system's pip.
Well, doah.... I'm using venv because I want those localized, not so I get an extra venv folder but then still have to pollute my system's site-packages with that project's dependancies. So either something's wrong with my setup, or my conception of what a virtual environement should do is off.
What I expected:
I expected that Pycharm would install that depencides locally. I would expect to see it (along with all global site packages) if I do pip list in that virtual env. I would expect to see the same thing EXEPT that new packages if I do pip-list in the system.
