Building Python-modules fails on MacOS Ventura

Dear experts,

Building O2 fails on Python-modules. I recently updated MacOS to Ventura 13.6.4, installed Xcode 15.2, reinstalled alibuild with brew, and updated alidist. Any hint? The log is very short:

++ unset VIRTUAL_ENV
++ python3 -m venv --copies /Users/auras/alice/sw/INSTALLROOT/adc369b7c6d438778cfefc7b00a9b2c289210c44/osx_arm64/Python-modules/1.0-local1
Error: Command ‘[’/Users/auras/alice/sw/INSTALLROOT/adc369b7c6d438778cfefc7b00a9b2c289210c44/osx_arm64/Python-modules/1.0-local1/bin/python3.11’, ‘-m’, ‘ensurepip’, ‘–upgrade’, ‘–default-pip’]’ died with <Signals.SIGABRT: 6>.


Hi @auras, this is an odd one! The only reference to it that I found is Installing python on MacBook Pro M2 - ensurepip "died with <Signals.SIGABRT: 6>." · Issue #2707 · pyenv/pyenv · GitHub, which seems to suggest that something may be wrong with your Homebrew installation.

Did something go wrong during the OSX upgrade?

Can you reinstall Homebrew?

Hi @twilken , thanks for the hint! Before reinstalling Homebrew I tried to update python3 and it fixed the problem with the building of Python-modules. Unfortunately, I’m now stuck with the building of xjalienfs@1.5.9, but this is another story, I’ll open a dedicated ticket.
