I am running Pycharm under Ubuntu and am trying to get Kivy installed in my project (virtualenv). I followed the Kivy instructions but those install it in the default environment. So, at my terminal prompt when I go into python I am able to successfully "import kivy". However, when I am in a Pycharm project with virtualenv, I get an error when I try to import from the Python console:

import kivy
Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "/mnt/bigdisk/apps/pycharm-2017.3.4/helpers/pydev/_pydev_bundle/pydev_import_hook.py", line 20, in do_import
    module = self._system_import(name, *args, **kwargs)
ImportError: No module named kivy

I've even tried activating the virtualenv in my terminal and then performing the installation instructions. When I do this, I am told it is already installed. I think this is happening because to install kivy you have to make a sudo call (sudo apt-get install python-kivy) which is resetting the environment. I even tried sudoing to bash activating the environment and installing python-kivy, but again, it said it was installed. How do I get Kivy installed in my Pycharm virtual environment?

apt-get install python-kivy installs kivy for a system interpreter and not inside a virtualenv no matter what sudo tricks you did. There's a special paragraph in the official docs for installing kivy inside a virtualenv: https://kivy.org/docs/installation/installation-linux.html#installation-in-a-virtual-environment
