I used sudo apt-get install python3.6-tk and it works fine. Tkinter works if I open python in terminal, but I cannot get it installed on my Pycharm project. pip install command says it cannot find Tkinter. I cannot find python-tk in the list of possible installs either. 
Is there a way to get Tkinter just standard into every virtualenv when I make a new project in Pycharm?
Edit: on Linux Mint
Edit2: It is a clear problem of Pycharm not getting tkinter guys. If I run my local python file from terminal it works fine. Just that for some reason Pycharm cannot find anything tkinter related.
Python already has tkinter installed. It is a base module, like random or time, therefore you don't need to install it.
how to install tkinter with Pycharm?
