how to install tkinter with Pycharm?
For python 2 use:
sudo apt-get install python-tkFor python 3 use:
sudo apt-get install python3-tkWhen you display info about packages it states:
Tkinter - Writing Tk applications with Python2 (or Python 3.x)
But my assumption is that PyCharm created it's own virtualenv for you project, so you are probably using wrong python interpreter in PyCharm.
Open your PyCharm project. Go to File->Settings->Project->Project Interpreter. At top, you will see what python interpreter is PyCharm using for a current project. If that's not the system one you have, find path to system interpreter and add it to Python Interpreters in PyCharm.
