python virtualenv import failures

My source tree is as follows. I am using python3.7:

proj/
  src/
    __init__.py
    module1.py
    module2.py
  venv
  __main__.py

__main__.py imports module1, which imports module2. I am running this in a virtual environment. See below:

In __main__.py:

import src.module1
...

In module1.py:

import module2
...

Note that I do have the __init__.py file in the src directory.

When I run __main__.py, I end up getting an import error:

ModuleNotFoundError: No module named 'module2'

What I have found is if I run the program outside of the virtual environment, module1 is able to import module2, but in the venv, I hit this error. I am stumped as to how to get this work properly as I believe I have done everything correctly here, using absolute imports and an __init__.py.

Python import's are so sensitive! I broke my entire project the other day...

First:

export PYTHONPATH=/path/to/proj/

Secondly:

import src.module2

Thirdly: In main.py if you are calling a single function or variable do

from src.module2 import x,y

Do this instead of ... import *

The absolute paths were not used within the src modules, so I wasn't actually using absolute paths, which was my problem. In other words, change module1.py to be:

import src.module2
...
