Key errors while running pytest #3112

nbharadwaj11 · 2018-01-12T20:12:22Z

Thanks for submitting an issue!

Here's a quick checklist in what to include:

Include a detailed description of the bug or suggestion
pip list of the virtual environment you are using
pytest and operating system versions
Minimal example if possible

I have been seeing key errors while running pytest.
I have a test suite written in pytest, and when I try to run it, I see the following errors all the time:

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/_pytest/config.py", line 328, in _getconftestmodules

    import pandas as pd
ModuleNotFoundError: No module named 'pandas'
ERROR: could not load /Users/nbharadwaj/code/thewall/conftest.py

My system was is running 2 versions of python. Python 2.7 and Python 3.6

Python 3.6 is what my test suite is written on. I have tried uninstalling and reinstalling python3.6 multiple times, but have not had any luck with it so far. I am using pycharm as my IDE.

pytest version: 3.3.2
operating system: MacOS Sierra 10.12.6

Can someone please help me on this?

The problem seems to be:

ModuleNotFoundError: No module named 'pandas'

You are importing pandas in "/Users/nbharadwaj/code/thewall/conftest.py", line 6 but that doesn't seem to be installed. Try executing:

sudo pip install pandas

(I see you are not using a virtual environment, I would recommend to use them in the future)

I installed Pandas, and now I see the following errors:

There's nothing wrong with the testsuite, because it seems to be running just fine for a few of my friends.

The-Compiler · 2018-01-12T21:48:19Z

It looks like an issue reported by Pandas while parsing your test.json - this is entirely unrelated to pytest though, and you'd probably get the same error if you just run your conftest.py with python.

nicoddemus · 2018-03-21T21:14:55Z

I'm closing this for now because of lack of feedback, but feel free to follow up if there is more information available.

please start using the actual github code formatting instead of dumping unreadable massive posts 😠

yozlet · 2018-07-13T23:39:50Z

Try deleting all your .pyc files: #3058 (comment)

This is a problem I've seen when using the same project folder with two very different environment contexts. In my case, it happens when switching between Mac OS and Docker; .pyc files created in one environment stick around in the folder, and when running python in the other environment, it chokes with similar errors. I think it's because the path to the folder has changed.

towc · 2019-04-23T12:21:37Z

I've come to the same github issue, when I clearly had no reason to. Because of that, I think this is a pytest issue, in that the error message should make it clearer that it's not a pytest issue, so people like me don't end up here.

The reason I thought it was a pytest issue is that the first couple exceptions were key errors, and all others occur "during handling of the above exception". Can this be fixed?

Some message along the lines of "WARN: the error actually seems to originate with your code, disregard KeyErrors" would have saved some time :)

The-Compiler · 2019-04-23T12:29:47Z

@towc The output for the scenario mentioned in this issue already got improved, see #3332. What pytest version are you on, and what's the exact output you get?

towc · 2019-04-23T12:35:45Z

oh, sorry. 3.8.2, guess I better update :)

The-Compiler · 2019-04-23T12:42:03Z

Yep, that change landed in 3.9. So yeah, you did indeed clearly not have any reason to come to this issue 😉

Azee77 · 2020-06-24T05:16:01Z

Any resolution for this issue?
#3112 (comment)

pytest 5.0
running pytest command from pytest.ini directory, there is only one conftest.py inside the directory
Tried clearing all .pyc files, pycache directories, didnt help.

Using custom pyenv: Is this the culprit?

The-Compiler · 2020-06-24T11:31:58Z

@Azee77 I doubt you're seeing the same issue, given that the stacktrace above points to a custom conftest.py. Can you show the actual output you get?
