[`1.16.0`] `hatch version` fails with "No module named hatchling"

[dhirschfeld]

CI broke yesterday with the above error when running hatch version.

Pinning hatch<1.16 fixed the problem for us.

Please provide more information about where this is being run, what OS? What Python version? How hatch is being installed in your CI?

[dhirschfeld]

Linux container in CI Python version 3.10. Hatch is being installed from PyPI using pixi.

The output from CI is:

++ hatch version
Creating environment: hatch-build
Checking dependencies
Syncing dependencies
Inspecting build dependencies
/home/runner/.local/share/hatch/env/virtual/mypkg/dkW19B8f/hatch-build/bin/python: No module named hatchling
+ version=
Error: Process completed with exit code 1.

Just tested with 1.16.1:

Same error unfortunately.

Edit: hatchling is actually installed.

[dhirschfeld]

I can't repro locally unfortunately

❯ hatch --version
Hatch, version 1.16.1

❯ hatch version
0.47.2.post.dev001+dirty

So, it's something specific to the CI, even though I'm installing the same environment locally as in CI :/

[cjames23]

Are you putting the output of version into GITHUB_OUTPUT? Wondering if it is the same issue as https://github.com/pypa/hatch/issues/2107#event-21232683998 Which there has been a fix that has been merged, expecting to release next week for this.

[dhirschfeld]

~~Nope - literally just running version=$(hatch version)~~

Actually it's running:

version=$(hatch version)
echo "path=${BUCKET}/${repo#*/}/${folder}/${version}" >> "$GITHUB_OUTPUT"

So yeah - it looks like it's putting the output into GITHUB_OUTPUT (though it doesn't seem to ever get to that line)

Edit: Also, I'm not setting HATCH_VERBOSE

[dhirschfeld]

I mapped my local checkout into a container, installed the env and hatch version works there.

It's just in my CI container where it fails... which is very odd, and very hard to debug :pensive:

[cjames23]

Can you share what your CI setup looks like for steps that install hatch before calling hatch version? I think I have an idea what is causing this but I need to try to reproduce this in a local container.
