Kedro project initialization fails due to missing module

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

something like pip install --editable . (with . being the path where pyproject.toml is)

otherwise pytest won't find any local modules you have under src/{project_name}

could you try that?

Sure! Will try that now.

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

On a new project kedro_foo I got this after following the steps (including running pip install --editable . )

\kedro_foo\foo> pytest

Oh, sorry the project is called foo . kedro foo is just a folder I made above it.

"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

you can either pip install pytest-cov or tweak the pytest config

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

Okay, that definitely changed the error:

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).

Or an issue that I had not yet created a pipeline in project foo?

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.
