Module Not Found Error: No module named 'src'

Question

Whenever I run main.py in the terminal, I get the error

ModuleNotFoundError: No module named ‘src’

However it runs fine in PyCharm.

Project Structure:

-project
  -resources
  -src
    -package1
      -script1.py
      -script2.py
    -package2
      -script3.py
    -main.py

This is what I run in the terminal:

project$ python src/main.py

Error:

Traceback (most recent call last):
  File "src/main.py", line 1, in <module>
    from src.package1 import script1
ModuleNotFoundError: No module named 'src'

I have already tried adding absolute path of folder/package ‘src’ to sys.path

main.py

from src.package1 import script1
from src.package1 import script2
from src.package2 import script3

if name=="__main__":
  ...
  ...

sys.path

current sys.path is ['/home/xyz/Projects/project/src', '/home/xyz/Apps/anaconda3/envs/project/lib/python37.zip', '/home/xyz/Apps/anaconda3/envs/project/lib/python3.7', '/home/xyz/Apps/anaconda3/envs/project/lib/python3.7/lib-dynload', '/home/xyz/Apps/anaconda3/envs/project/lib/python3.7/site-packages', 'src/main.py']

https://docs.python.org/3/tutorial/modules.html#the-module-search-path

When a module named spam is imported, the interpreter first searches for a built-in module with that name. If not found, it then searches for a file named spam.py in a list of directories given by the variable sys.path. sys.path is initialized from these locations:

The directory containing the input script (or the current directory when no file is specified).

PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH).

The installation-dependent default.

Since you supply a file, src/main.py, its containing folder is going to be the search root. You could import the modules without specifying the src. part.

You can add a path to python runtime using sys.path:

import sys
sys.path.append('src/package1')
import script1

You should be able to run it with project$ python -m src.main
