"uv add pybullet" throws cpp compilation error when compiling the wheel

[cube1324]

Hello,

when i try to add pybullet via uv add pybullet i get some c++ compilation error:

error: Failed to prepare distributions
  Caused by: Failed to fetch wheel: pybullet==3.2.6
  Caused by: Build backend failed to build wheel through `build_wheel()` with exit code: 1

However installing pybullet via uv pip install pybullet works flawlesly. I am using Windows 11 with uv version 0.4.9. I already tried to disable build isolation but that does not solve the issue. Is there anything else i have overlooked or is the package just too old / not compatible?

[charliermarsh]

That's interesting... Are they using different underlying Python interpreters? (If you run with --verbose, we should tell you the Python interpreter that's being used in each case.

[cube1324]

Below are the debug messages for both cases. As far as i understand uv pip install uses the venv interpreter and uv add uses the miniconda interpreter. Installing pybullet without uv with just plain pip works for the minicoda intepreter. I tried a default python interpreter instead of the miniconda one in case there are some weird permission issue. However it still has the same issue.

Does pip install --use-pep517 --no-cache pybullet work? Or does that fail too?

[cube1324]

pip install --use-pep517 --no-cache pybullet works with no issues. Only uv add fails

[charliermarsh]

My best guess is that you're hitting the file-length limit on Windows?

[charliermarsh]

Can you try setting a short cache directory? https://github.com/astral-sh/uv/issues/7078#issuecomment-2333152223

[cube1324]

Setting a short cache directory fixes the issue 👍, thanks for the help. The only weird thing is that long path support is already enabled on my machine, so i am not sure why it doesent work with the longer path 🤔. I guess its just windows things....

[charliermarsh]

That's interesting...

I do have a PR open to try and shorten the paths: #7240. It's hard for me to say off-hand whether it would've made a difference here, would need to do some character counting (or you're welcome to try it if you're eager to build from source)...

[charliermarsh]

Annoyed because this actually worked for me on my Windows machine, even without long paths enabled.

[cube1324]

I tried on 2 different Pc both running Windows 11 10.0.22631. On both it does not work with the default cache location. The long path settings has not impact. However if i move the cache location to C:\uv it works. I dont have time to investigate it further, for the time being i will just stick with our previous slow build pipeline 😢. Thanks for the help anyways!

[charliermarsh]

Is moving the cache location a problem?

[cube1324]

After some more consideration i agree with you, moving the cache location is not a big issue. Thanks again 👍

[bmarroquin]

Sadly, not everything in windows respects the long path setting. In this case, the executable that is raising the error does not. See this stack overflow question.. The safer bet is always trying to shorten the paths.

Since there is a user specific part in the path (username), the error may or may not be present depending on the length of the user's username. This may explain why it works for @charliermarsh without any changes.
