ModuleNotFoundError: No module named 'memoize'

Question

I tried this,

pip install memoize
Requirement already satisfied: memoize

But every time i run pytest, I get the above error ModuleNotFoundError: No module named 'memoize' and it fails to load the conftest.py file even though it is in my tests folder and it also contains an __init__.py file.

any suggestions what else could be wrong/missing?

Could be because of the python path issue have you tried *python -m pytest projectrootdir/* — Naresh Kumar, Dec 14 '17 at 04:38
what does the -m stand for? I have issues with pylint as well...`unable to import memoize (import-error)` — julian joseph, Dec 29 '17 at 04:24
you can check `python --help` for more details on arguments. The issue is with the path variables you might be having different version python/modules and your root project folder is not in the `sys.path` for python to process it correctly. — Naresh Kumar, Dec 29 '17 at 06:58

The python path could be the issue

python -m pytest projectroot/

To fix this you could also set the path using

import sys, os
myPath = os.path.dirname(os.path.abspath(__file__)) 
sys.path.insert(0, myPath + '/../')

The above command helped pytest work. but linter raises this `Unable to import 'memoize' (import-error)` any idea how to avoid this. I tried uninstalling the global version, and installing `memoize` again. didn't help – julian joseph Dec 29 '17 at 04:45
Could you provide your project tree structure? You can also check the following doc [PYTHONPATH](https://docs.python.org/3/using/cmdline.html#envvar-PYTHONPATH) .
