Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: No Cask quarantine support available: unknown reason.

Warning: Your Command Line Tools are too outdated.
Update them from Software Update in System Settings.

If that doesn't show you any updates, run:
  sudo rm -rf /Library/Developer/CommandLineTools
  sudo xcode-select --install

Alternatively, manually download them from:
  https://developer.apple.com/download/all/.
You should download the Command Line Tools for Xcode 15.2.


Warning: Some installed kegs have no formulae!
This means they were either deleted or installed manually.
You should find replacements for the following formulae:
  python-jinja
  python-idna
  python-requests
  python-urllib3
  python-charset-normalizer
  python-markupsafe

Warning: Some installed formulae are deprecated or disabled.
You should find replacements for the following formulae:

Warning: Unbrewed header files were found in /usr/local/include.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae and may need to be deleted.

Unexpected header files:
  /usr/local/include/node/*

Warning: You have unlinked kegs in your Cellar.
Leaving kegs unlinked can lead to build-trouble and cause formulae that depend on
those kegs to fail to run properly once built. Run `brew link` on these:

Warning: You have an unnecessary local Cask tap.
This can cause problems installing up-to-date casks.
Please remove it by running:
  brew untap homebrew/cask

Warning: You have an unnecessary local Core tap!
This can cause problems installing up-to-date formulae.
Please remove it by running:
 brew untap homebrew/core

Warning: Your Xcode (11.4 => /Applications/Xcode-beta.app/Contents/Developer) at /Applications/Xcode-beta.app is too outdated.
Please update to Xcode 15.2 (or delete it).

Description of issue

I want to install PyObject on my Mac (Ventura 13.7.4) so I run:

bill@iMac Examples % brew install pygobject3 gtk4
==> Downloading https://formulae.brew.sh/api/formula.jws.json
==> Downloading https://formulae.brew.sh/api/cask.jws.json
Warning: pygobject3 3.50.0_1 is already installed and up-to-date.
To reinstall 3.50.0_1, run:
brew reinstall pygobject3
Warning: gtk4 4.16.12 is already installed and up-to-date.
To reinstall 4.16.12, run:
brew reinstall gtk4

After testing the installation with a simple "hello" Python script I get:

bill@iMac Examples % python3.13 hello.py
Traceback (most recent call last):
File "/Users/bill/Projects/Software/Python /Examples/hello.py", line 3, in
import gi
ModuleNotFoundError: No module named 'gi'

Homebrew says it's there, but a search for anything like pyobject 3 or gi renders nothing!

Where could this be?

[gromgit]

What's the output of type python3.13 python3?

[bbabbitt]

python3.13 is /Library/Frameworks/Python.framework/Versions/3.13/bin/python3.13
python3 is /Library/Frameworks/Python.framework/Versions/3.13/bin/python3

[SMillerDev]

Neither of those are Homebrew installs

[bbabbitt]

Does that make a difference? Do I need to do Brew install python3.13?

[gromgit]

Does that make a difference?

All the difference in the world. Each Python installation has its own package installation directory, so one Python will not see another Python's packages.

Do I need to do Brew install python3.13?

brew install [email protected], make sure type python3.13 outputs python3.13 is /usr/local/bin/python3.13, then you should be good to go.
