Installing ruff v0.1.9+ with mamba and conda produces ModuleNotFoundError on Linux

[sogoodmo]

Mac - Works
Linux - Fails
Windows - Not tested

• Importing ruff from mamba or conda on linux based machine and running python file that has import ruff produces ModuleNotFound error.
• Importing ruff from pip on linux based machines does work
• Testing with python file that includes only import ruff
• Installed ruff by doing mamba install ruff==0.1.9 Note: <0.1.8 versions don't produce this error
• Ruff version installed 0.1.9 py310h3d77a66_0 conda-forge/linux-64

Note:

• Using ruff in terminal to check a file does work on v0.1.9+ but importing it into my python file doesn't work.

Interesting, need to see what changed here... The only thing I can see that possibly touched the release between v0.1.8 and v0.1.9 is #9031, but I don't see how it would've led to this error. Could something have changed in the conda-forge setup?

[charliermarsh]

Hmm, no, nothing changed between those releases in https://github.com/conda-forge/ruff-feedstock.

Does python -m ruff work? I assume not.

Does python -m ruff work? I assume not.

Nope it doesn't :(.

The problem is that in the new release, the ruff folder isn't installed into the site-packages anymore, while the dist-info still is. In the env site-packages:

$ micromamba install ruff==0.1.8
$ ls
_distutils_hack  distutils-precedence.pth  pip  pip-23.3.2-py3.12.egg-info  pkg_resources  README.txt  ruff  ruff-0.1.8.dist-info  setuptools  setuptools-69.0.3-py3.12.egg-info  wheel  wheel-0.42.0.dist-info
$ micromamba install ruff==0.1.9
$ ls
_distutils_hack  distutils-precedence.pth  pip  pip-23.3.2-py3.12.egg-info  pkg_resources  README.txt  ruff-0.1.9.dist-info  setuptools  setuptools-69.0.3-py3.12.egg-info  wheel  wheel-0.42.0.dist-info

I assume this is a conda bug since there is no , but it's hard to even find out the correct build commands to verify a regression.

[sogoodmo]

Ah so is this not a ruff issue, but rather a conda bug?

And is it just a coincidence that 0.1.9 has #9188 as a breaking change and the problem is related to ruff not being found in the site-packages?

[konstin]

It's either a bug in the conda feedstock or in conda itself, i'm not a conda expert though; We build the wheel as basis for the conda package and we know that the wheel version works.

Hey just updating, there is an open issue conda-forge/ruff-feedstock#153 here detailing the same problem

[sogoodmo]

Update: This issue seems to be fixed with 0.1.13 version. We can close this.

Good to hear, thanks for reporting back!
