What version of Python and Zope/Addons I am using:

macOS Monterey (same issue after upgrading to Ventura)
Homebrew with pyenv 2.3.5 and pyenv-virtualenv 1.1.5
Python 3.8

Looks like a bug in cffi; see https://foss.heptapod.net/pypy/cffi/-/issues/518

jpmckinney commented 2 years ago

Aha, thanks, I had tried web search and didn't come across that result.

That ticket notes that there might be a clue in my output above:

Using cached ...

I ran pip cache purge, and now (since I upgraded to Ventura) I'm getting an error related to Command-Line Tools not being installed. I ran xcode-select --install and re-ran pip cache purge... but simply reproduced the above output.

Anyway, since it's not a persistent issue, I'll let you decide whether to close.

Edit: As noted in the linked ticket, temporarily moving mv /usr/local/bin/brew /usr/local/bin/brew_ before creating a virtualenv with pyenv allows pyenv to select the system cffi instead of Homebrew's.
