Brew Aider fails to find model, but pip version does

[PaulWaldo]

Issue

I am running macOS Sequoia 15.1.1. I have tried out aider using the pip-installed version in a virtual environment. It successfully connects to the model:

(aider-env) paul@Mini aider-test % python -V
Python 3.9.6
(aider-env) paul@Mini aider-test % aider --model ollama_chat/codellama:7b

Now I want to use it in a non-python project using the version installed by brew. This install fails to connect to the same model:

paul@Mini glimmer % which aider
/opt/homebrew/bin/aider
(aider-env) paul@Mini aider-test % /opt/homebrew/bin/aider --model ollama_chat/codellama:7b

I was expecting that both versions would be able to connect to the model. Note that system version of python is

paul@Mini glimmer % which python3
/opt/homebrew/bin/python3
paul@Mini glimmer % python3 -V
Python 3.13.0

Version and model info

Aider v0.66.0

Thanks for trying aider and filing this issue.

It's not recommended to install aider via brew. Installation via pip or pipx is recommended.

Likely you've picked up a newer version via pip than you got via brew.

Note that aider only works with python 3.9-3.12, not 3.13.

[PaulWaldo]

I was able to get it working using a global pip install, thanks. I'm curious if it is the brew install that caused the problem or Python 3.13. If the latter, can it be resolved if the brew dependencies listed 3.12 or less?

[paul-gauthier]

It won't install at all with python 3.13. See #1984

I'm good with the python version requirements, the working versions might be documented on the website to prevent similar issues 😁

[paul-gauthier]

It should be well documented on the install page now:
