I'm trying to make an exe out of a Python file that uses apscheduler, sqlalchemy, and Tkinter among other libraries. Once compiled, the majority of the app works fine, except for one function that needs to add jobs to the SQLite database. The most recent error is involving this six library. I've tried downgrading it to 1.4.0, even using '--collect-all six' but that just doesn't launch the app.

I don't know what this six library is really used for.
