@shohidulhaque you didn't mention which version of macOS or CPU architecture (Intel or Apple Silicon) you're getting this on.

I'm getting it on macOS Sonoma 14.7.2 on Apple Silicon (M3 Pro). This r/MacOS subreddit thread had a user report this on macOS 13 and 14, but not 15 on Apple Silicon.

One other thing: since this is my work Mac I have Homebrew installed to a subdirectory in /Users/${USER}, so most brew packages I have to compile from source.

Hi, I'm using a Intel based mac with version 14.2 (Sonoma), and I can't reproduce the error:

❯ brew reinstall python@3.13 -s

You're on your own. Failures are expected so don't create any issues, please!

I'm experiencing the same, also on an M3 chip

[hangxie]

Remove --with-system-expat from configure works for me, I'm not using XML/expat so someone can help to check if they still work after this.

I feel like python 3.13 needs newer version of expat (2.6.4?) and that's why Sequoia works, however this does not explain why it works under Intel chips.

EDIT found #125067 (comment)

[hangxie]

3.13.2 solved this problem https://github.com/orgs/Homebrew/discussions/5805#discussioncomment-12100850

[picnixz]

I guess this can be closed then?

Sounds good to me.

For people who want 3.13.1 specifically (sounds weird but anyway), they can backport the patch to their local formula.
