Output of brew doctor

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:
  librsvg

Warning: You are using macOS 10.15.
We (and Apple) do not provide support for this old version.
It is expected behaviour that some formulae will fail to build in this old version.
It is expected behaviour that Homebrew will be buggy and slow.
Do not create any issues about this on Homebrew's GitHub repositories.
Do not create any issues even if you think this message is unrelated.
Any opened issues will be immediately closed without response.
Do not ask for help from Homebrew or its maintainers on social media.
You may ask for help in Homebrew's discussions but are unlikely to receive a response.
Try to figure out the problem yourself and submit a fix as a pull request.
We will review it but may or may not accept it.

ERROR: Unhandled python OSError. This is probably not a Meson bug, but an issue with your build environment.

Textfile version of the 03.meson logfile is attached.

03.meson.txt

While the built-in analysis suggests a build environment error, it's hard to determine the root cause (if true) as the only reason Python 3.12/3.13 are installed (via Homebrew) was as build dependencies of leaf formulae, so there is only the base Python environment. libpixbuf permissions seems to be the cause, but again, nothing has changed except for updates to formulas which would introduce this and all previous versions successfully build on Catalina.

Choose Apple menu  > System Preferences, click Security & Privacy, then select the Privacy tab. Scroll down and click Full Disk Access and tick the checkbox in front of the terminal app you are using to run the upgrade command e.g Terminal.

[OldCrow]

No, didn't work. I confirmed full disk access for Terminal and iTerm (and sh), but still get the same issue:

Bump!

Any suggestions how to resolve this? On Monterrey is the same issue

Try doing

brew update
brew reinstall gdk-pixbuf

to see if that helps with the build failure for librsvg.

[julienchauveau]

That's fixed the issue for me. Thank you!

[OldCrow]

Also worked for me (well, sort of - gdk-pixbuf and expat both showed up as outdated when I ran brew update, so effectively it ended up being an update because the new versions installed). Guess it was a dependency chain issue in the end. But librsvg, and more importantly fastfetch, are now updated.

Thanks!

[way5]

I also confirm, this works on Monterrey.
Thank you @carlocab
