Tkinter in raspberry pi bash

Question

I am able to import tkinter in idle3 and used it to create a simple application and in Idle3 everything works great. The problem is, if I try to start the program from bash, I get the error:

ImportError: No module named 'tkinter.filedialog'; 'tkinter is not a package

Why would the pi be able to run a program in idle3 but not when start with

python3 program.py

It seems to be that idle3 recognizes the tkinter package but my bash cannot. Any Solutions?

Answer 1

The only thing I can think of is that it's being run with python instead of python3

Make sure the shebang line is #!/usr/bin/env python3
