Kivy: How do I make external libraries work?

Question

I have a script where I'm using fbconsole and twitter. Those scripts run fine on their own.

For the GUI part, I'm trying to use Kivy. Now when I'm importing my script, I'm getting a error ImportError saying there's no module named twitter/fbconsole. What do I do?

I checked the path that is displayed when the kivy app is run. Here's the complete log

Answer 1

As you are using kivy's portable bundle for windows, you have to install the libraries in the python installation that's shipped with it. To do so, you just have to start the kivy.bat, and use pip install inside of it, the libraries installed this way will be available for the kivy applications.

The alternative solution, is to install kivy system-wide, with all the required dependencies.

Answer 2

You have to edit PYTHONPATH to include the folders where python can find fbconsole and twitter.

That way import will find them in sys.modules.
