Homebrew fails to install mopidy, "No module named 'setuptools'" (Sonoma 14.4.1, M3)

[limsammy]

Hello!
This may potentially be related to #37 , or it's my Python installation.

I'm setting up all my old dotfiles and configurations on my new M3 Pro Macbook running Sonoma 14.4.1.

Python install information

• Using pyenv to manage installations
• Currently have global set to Python version 3.12.3 (outputs with python --version)
• Using pipx for packages like poetry, mypy, black, etc. that I want available globally; the ones I don't want to reinstall for each virtualenvironment
• Here's brew info python3 for more info (same version):

How I reached this error:

1. As per documentation, I started by tapping the keg: brew tap mopidy/mopidy
2. I then proceed to run the install command via brew: brew install mopidy

The following is the command output & error, the error being setuptools not being installed.

It seems like setuptools cannot be located with brew. Does anyone have any advice?

I ran easy_install --version to verify if setuptools is installed and easy_install is not installed either (zsh unrecognized command)

[limsammy]

Huh, I actually just fixed it right after I posted this issue. Installing setuptools with pip (pyenv), pip3 (brew installation), pipx, etc. wasn't working, so I did a brew install python-setuptools (Found here: https://formulae.brew.sh/formula/python-setuptools).

I then re-ran brew install mopidy and it successfully installed. Will leave this open for the timebeing if maintainers think it may be useful to add python-setuptools as a prerequisite to the brew formulae (I'm not 100% sure how brew formulas work)

[jdeltoft]

Thanks, this worked for me also. Might be ok to close this?

[jodal]

Did you have to install python-setuptools before it worked?

[jdeltoft]

Yes, as per comment above

I did a brew install python-setuptools (Found here: https://formulae.brew.sh/formula/python-setuptools).
I then re-ran brew install mopidy and it successfully installed.

I am having a different overall issue with mopidy though on 2019 MacBookPro (intel). I have

• python 3.12.10
• Homebrew 4.5.2

But I run into this failure when running from the terminal:

https://discourse.mopidy.com/t/mopidy-crashes-on-manual-startup-macos/6102/3

I tried using 3.9 python and debugged a bit further but still not familiar with the overall structure of mopidy.

I did use brew search mopidy to see other possible modules and installed the following successfully:

• mopidy/mopidy/mopidy
• mopidy/mopidy/mopidy-local
• mopidy/mopidy/mopidy-mpd
• mopidy/mopidy/mopidy-spotify

But that still doesn't help running mopidy from terminal and I'm not yet sure on running as a service either unfortunately.

Are someone able to test if this is resolved with the merge of #47?

it doesn't. I just had exactly the same issue:

Any progress on this? Any workaround?

The only Mac I have access to is too old to be supported by Apple and Homebrew, so I am not able to work out this on my own.

I'll merge any PRs that seem like reasonable improvements.

Managed to create a working fork: https://github.com/jonatan-verstraete/homebrew-mopidy.
Edited the formula and steps are in the readme.

Hope this helps someone, it's super hacky... would personally suggest to wait until a stable version of Mopidy 4 is out.

Issue & solution:
Mopidy 3.x assumes certain Python packages (e.g., setuptools/pkg_resources, pykka, PyGObject)
are available globally. Homebrew installs Mopidy into an isolated virtualenv, which:

• does not see global packages
• does not automatically install all Mopidy dependencies
• blocks system/global pip installs
  As a result, imports like pkg_resources fail unless dependencies are manually installed
  inside the same venv or system paths are adjusted. Switching to Python 3.11 avoids some
  ecosystem mismatches, making the venv + manual dependency install work.

thx, also had to
/opt/homebrew/bin/python3.11 -m pip install --upgrade "setuptools<82"
