Imports not found when running script outside of Pycharm?

问题

I have a project structured this way...

main.py imports scripts from subfolders like so:

from controllers.available_balances_controller import available_balances_controller

Subfolders:

• models
• views
• controllers

When running main.py in Pycharm it works find.

When I try to run in terminal I get import errors:

Traceback (most recent call last):
  File "main.py", line 6, in <module>
    from controllers.available_balances_controller import available_balances_controller
ImportError: No module named controllers.available_balances_controller

Am I importing the scripts wrong in main.py?

What is the proper way to do the importing?

回答1:

Try running your script with the -m flag:

$ python -m main

That means that you are running your main.py as a module inside a python package, not as a simple script. PyCharm makes it easy for you by assuming so when you create a project. When you are in the terminal, you need to specify it yourself. You don't need __init__.py files inside your directories in Python3.
