Coveragepy: ModuleNotFoundError: No module named 'django_project' when I used coverage run manage.py test

Created on 24 Oct 2019  Β·  37Comments  Β·  Source: nedbat/coveragepy

The below issue is with Coverage version 5.0a7

When trying to run test for my django project using coverage run manage.py test i get
ModuleNotFoundError. This issue kept coming and i thought it was as a result of what was addressed here --> https://stackoverflow.com/questions/50378166/django-coverage-modulenotfounderror-no-module-named-django-extensions

None of the recommendations worked, i downgraded my django version from 3.0 to 2.2 and the problem persisted. This issue was rectified by downgrading to coverage version 4.5

Like i said, i only encountered this issue with coverage version 5.0a7

With the below dependencies, coverage is working as expected

For those facing this problem: a work-around seems to be to use "python -m coverage run (etc)" instead of "coverage run (etc)".

Hmm, this sounds concerning. Can you give me a way to reproduce the problem?

nedbat picture nedbat on 24 Oct 2019

I started off by creating a virtual environment in my project directory and activating the virtual environment.

Within the activated environment I installed django and coverage ( didn't explicitly specify any version number, so the latest versions was installed -- django v3.0b and coverage v5.0a7), I then created a simple django model for an app and Test Cases for the model... With the TestCases created, I tried running coverage on my codebase and I get the above error.

The error only occur when I run coverage run manage.py test but other coverage commands worked without any errors...

Don't mind my response if it doesn't meet with what you expected, this is my very first bug report ( with a response ), I'm glad and willing to push the conversation further if need be

@spaceofmiah I'm looking for very specific instructions. Exactly what code did you run? Do you have a GitHub repo I can use? Exactly what commands did you run? Ideally you would literally include "git clone ...." commands and so on.

nedbat picture nedbat on 25 Oct 2019

You can use this github repo https://github.com/spaceofmiah/coverage_report

The instructions/commands to be used are highlighted on the README

spaceofmiah picture spaceofmiah on 25 Oct 2019

Thanks for the instructions, but I'm not seeing the error you are. I had to skip the "pipenv shell" step, because it threw an error, perhaps due to my zsh setup?

Here's what I saw:

I fixed my issue with "pipenv shell" (a bad installation of Jython...), and I still don't see the error. I don't know what could be different between our environments. Can you add this to the top of manage.py:main():

import pprint
pprint.pprint(sys.path)

and see what the difference is between the two versions of coverage.py?

What version of Python exactly are you using? What do you see when you type just "python"?

nedbat picture nedbat on 31 Oct 2019

I'm using python 3.6.2
when i type just "python", python interpreter is opened

@spaceofmiah did you find a fix for this? I'm also running into a similar issue. Interestingly, the command coverage run manage.py test is successful on Travis CI, but doesn't work locally. Running python manage.py test is successful locally. Repo

@mpbrown Can you give me instructions for reproducing it?

nedbat picture nedbat on 27 Dec 2019

@nedbat After cloning the repo, first run npm run setup and npm run assets to set up the environment using npm scripts. Then npm test to reproduce the ModuleNotFoundError.

Also I should note that the coverage command was previously working correctly even in November.

@mpbrown Thanks, but it's not failing for me. Something fundamental is different on my machine than the other people who can reproduce this. This is what I am seeing:

Same problem here.
Python 3.6.8 [MSC v.1916 64 bit (AMD64)] on win32
No Problem with coverage==4.5.4
Fail with coverage==5.0.2
When I look at this thread, I see that @spaceofmiah runs Windows but @nedbat does not.
@mpbrown, do you use Windows too ?

Same thing as above but with Python 3.7.4 (tags/v3.7.4:e09359112e, Jul 8 2019, 20:34:20) [MSC v.1916 64 bit (AMD64)] on win32

Seems to be windows issue since I don't get the ModuleNotFoundError with linux vagrant box. Coverage 4.5.4 is fine though.

Same, using coverage==5.0.2. Like others, coverage 4.5.4 works. Python is:

To reproduce in my environment:

# I don't think it matters that I use pyenv. Create the virtualenv however you want.
pyenv virtualenv coveragepy
pyenv activate coveragepy

pip install coverage==5.0.2 Django==3.0
django-admin startproject coveragepytest

@jpmckinney Thanks, I was finally able to reproduce it myself. Ironically, this turned out to be the important bit:

```

I don't think it matters that I use pyenv. Create the virtualenv however you want.

pyenv virtualenv coveragepy
pyenv activate coveragepy

It wasn't until I used pyenv and pyenv-virtualenv that the problem appeared for me. Now to work on a fix....

For those facing this problem: a work-around seems to be to use "python -m coverage run (etc)" instead of "coverage run (etc)".

Hi there, I am running into this error on Windows (but not Mac/Linux), when upgrading from coverage 4.5.4 to 5.0.2. I call coverage run test.py from tox and get the error:

Traceback (most recent call last):
  File "test.py", line 18, in <module>
    from tests.coloredtestrunner import ColoredTestRunner, ColoredTestResult
ImportError: No module named 'tests'

tox, and therefore coverage, is called from the project root directory, where test.py and the tests module are. Thanks for the workaround -- that works.

To try to help debug this error though:

Using coverage 4.5.4, printing sys.path from test.py yields:

['C:\\Users\\Ryan\\Documents\\NWB\\hdmf',
 'c:\\users\\ryan\\documents\\nwb\\hdmf\\.tox\\coverage-py35\\scripts\\python35.zip',
 ...']

Keeping everything else the same, except for telling tox to use coverage==5.0.2, printing sys.path from test.py yields:

['C:\\Users\\Ryan\\Documents\\NWB\\hdmf\\.tox\\coverage-py35\\Scripts\\coverage.EXE',
 'c:\\users\\ryan\\documents\\nwb\\hdmf\\.tox\\coverage-py35\\scripts\\python35.zip',
 ...']

The only difference between the two is that the first entry has been replaced with the path to coverage.exe. So test.py cannot be found.

But why does this error happen only on Windows? I suspect that these lines are the root cause:
https://github.com/nedbat/coveragepy/blob/b7e0eec3d794ee350f8a4392a0c9cc90fff54fa0/coverage/execfile.py#L164-L167
os.path.abspath(sys.path[0]) should be 'C:\\Users\\Ryan\\Documents\\NWB\\hdmf' in my use case, and os.path.abspath(os.path.dirname(top_file)) _might be_ 'c:\\users\\ryan\\documents\\nwb\\hdmf', and so the == comparison fails and sys.path[0] is overridden. I would guess this is not an issue on Mac/Linux because they handle path case differently. I would try normalizing the case of the paths or getting the paths with the correct case. I can't easily test this idea myself, but maybe this helps with a fix.

The root of the problem on windows is that distlib creates a zipapp for the launcher now, and zipapps dont put cwd on sys.path. if you run python -m coverage, you shouldn't run into the problem.

Subject: Re: [nedbat/coveragepy] ModuleNotFoundError: No module named 'django_project' when I used coverage run manage.py test (#862)

Hi there, I am running into this error on Windows (but not Mac/Linux), when upgrading from coverage 4.5.4 to 5.0.2. I call coverage run test.py from tox and get the error:

Traceback (most recent call last):
File "test.py", line 18, in
from tests.coloredtestrunner import ColoredTestRunner, ColoredTestResult
ImportError: No module named 'tests'

tox, and therefore coverage, is called from the project root directory, where test.py and the tests module are. Thanks for the workaround -- that works.

To try to help debug this error though:

Using coverage 4.5.4, printing sys.path from test.py yields:

['C:\Users\Ryan\Documents\NWB\hdmf',
'c:\users\ryan\documents\nwb\hdmf\.tox\coverage-py35\scripts\python35.zip',
...']

Keeping everything else the same, except for telling tox to use coverage==5.0.2, printing sys.path from test.py yields:

['C:\Users\Ryan\Documents\NWB\hdmf\.tox\coverage-py35\Scripts\coverage.EXE',
'c:\users\ryan\documents\nwb\hdmf\.tox\coverage-py35\scripts\python35.zip',
...']

The only difference between the two is that the first entry has been replaced with the path to coverage.exe. So test.py cannot be found.

But why does this error happen only on Windows? I suspect that these lines are the root cause:
https://github.com/nedbat/coveragepy/blob/b7e0eec3d794ee350f8a4392a0c9cc90fff54fa0/coverage/execfile.py#L164-L167
os.path.abspath(sys.path[0]) should be 'C:\Users\Ryan\Documents\NWB\hdmf' in my use case, and os.path.abspath(os.path.dirname(top_file)) might be 'c:\users\ryan\documents\nwb\hdmf', and so the == comparison fails and sys.path[0] is overridden. I would guess this is not an issue on Mac/Linux because they handle path case differently. I would try normalizing the case of the paths or getting the paths with the correct case. I can't easily test this idea myself, but maybe this helps with a fix.

Ah, thanks! Never mind my speculation then! :)

Not sure if this is the same problem: https://github.com/psf/black/pull/1227.

Black runs coverage run tests/test_black.py on GitHub Actions for Python 3.6, 3.7 and 3.8 on Ubuntu, macOS and Windows.

For some reason, the new Coverage.py version 5 is failing on Windows for Python 3.6 and 3.7.

Run coverage run tests/test_black.py
Traceback (most recent call last):
  File "tests/test_black.py", line 1788, in <module>
    unittest.main(module="test_black")
  File "c:\hostedtoolcache\windows\python\3.6.8\x64\lib\unittest\main.py", line 64, in __init__
    self.module = __import__(module)
ModuleNotFoundError: No module named 'test_black'
##[error]Process completed with exit code 1.

It's passing on Windows for 3.8, and all Python versions on Ubuntu and macOS.

Here's an older build that passed for everything, before Coverage.py 5 came out:

Pinning to coverage<5 for 3.6-3.7 on Windows is a workaround.

I have what I think is a fix for this problem. If people could try it and let me know, that would be a huge help:

pip install git+https://github.com/nedbat/coveragepy@nedbat/fix-862#egg=coverage==0.0

Hey @Ravi9562 we have same problem, please tell me if u have done with this problem. i really" help

jericore picture jericore on 2 Apr 2020

@Ravi9562 @jericore it sounds like you are having an issue with Django. This page is for issues with a different package, coveragepy, not Django. For help with Django, please consult the official Django help page or post your question on StackOverflow. Good luck!

rly picture rly on 2 Apr 2020

I was into same error for me it was just because of running in a lot of errors i just unintentionally did some typo or changed the app name in Procfile and now it works fine.

For those facing this problem: a work-around seems to be to use "python -m coverage run (etc)" instead of "coverage run (etc)".

A great solution for running coverage on Local.
