PATH issue with pytest 'ImportError: No module named YadaYadaYada'

Question

I used easy_install to install pytest on a mac and started writing tests for a project with a file structure likes so:

repo/
repo/app.py
repo/settings.py
rep         


        

Answer 1

I was having the same problem when following the Flask tutorial and I found the answer on the official Pytest docs It's a little shift from the way I (and I think many others) are used to do things.

You have to create a setup.py file in your project's root directory with at least the following two lines:

from setuptools import setup, find_packages
setup(name="PACKAGENAME", packages=find_packages())

where PACKAGENAME is your app's name. Then you have to install it with pip:

pip install -e .

The -e flag tells pip to intall the package in editable or "develop" mode. So the next time you run pytest it should find your app in the standard PYTHONPATH.
