I am getting some kind of environmental variable or config issue. The module for the project cannot be found. At first I thought it was just one project, but it seems to be something broader. On my system even creating a fresh project gives the same error. 1. I create a venv, and activate it. 2. Install kedro (pip install kedro), which is currently giving 0.19.9 3. Initialize new kedro project. 4. Run pytest (which gives a module not found error for the very project I just created). Troubleshooting advice would be appreciated.

hi @Galen Seilis, seems like you're missing 1 step which is installing your own project

Sure! Will try that now.

(to clarify, between (3) and (4))

@Juan Luis On a new project

kedro_foo

I got this after following the steps (including running

pip install --editable .

)

\kedro_foo\foo> pytest

"unrecognized arguments --cov-report --cov" looks like pytest is mandating those extra args (maybe

addopts

in the pytest conf) and you don't have

pytest-cov

installed

Ah, good idea. I see that it is not in my

requirements.txt

. I will try installing

pytest-cov

and then running

pytest

again.

it's in the

requirements.txt

of the default

kedro new

template, which is consistent with https://github.com/kedro-org/kedro/blob/ba981350ad57dbcaabf5fd758a9a3d4399a91f20/k[…]project/%7B%7B%20cookiecutter.repo_name%20%7D%7D/pyproject.toml

@Juan Luis Okay, that definitely changed the error:

Can you pass in a value there?

env=None

?

@Nok Lam Chan Certainly. I just tried it and the error was removed. Curiously, I did not touch that file at all since creating the dummy project

foo

. Is this something to change on the Kedro end, or something wrong with my setup? (I ran

kedro new

and then followed the prompts).

this was fixed 3 weeks ago https://github.com/kedro-org/kedro/pull/4159 will see the light in the new release 🙏🏼

Excellent! 🎉 Not a hard fix in the time being.
