Fix Python – How to fix “ImportError: No module named …” error in Python?

Question

Asked By – bodacydo

What is the correct way to fix this ImportError error?

I have the following directory structure:

/home/bodacydo
/home/bodacydo/work
/home/bodacydo/work/project
/home/bodacydo/work/project/programs
/home/bodacydo/work/project/foo

And I am in the directory

/home/bodacydo/work/project

Now if I type

python ./programs/my_python_program.py

I instantly get

ImportError: No module named foo.tasks

The ./programs/my_python_program.py contains the following line:

from foo.tasks import my_function

I can’t understand why python won’t find ./foo/tasks.py – it’s there.

If I do it from the Python shell, then it works:

python
>>> from foo.tasks import my_function

It only doesn’t work if I call it via python ./programs/my_python_program.py script.

Now we will see solution for issue: How to fix “ImportError: No module named …” error in Python?


Answer

Python does not add the current directory to sys.path, but rather the directory that the script is in. Add /home/bodacydo/work/project to either sys.path or $PYTHONPATH.
