Can you share the log? I think :Serge landed some work removing six usages recently, so that may be related, but it'd be a lot easier to track down with some error messages.

Sorry I should've included this in the original report:

./mach help

I was thinking of D207606.

I misread this though, this is a Python 3.12+ issue, so not caused by any removal (moreso, not all removals being done yet). The blocker on bug 1714690 is correct.

[Alex Hochheiden [:ahochheiden] [he/him]]

Though, there is bug 1857492, which implies it was fixed? I'll try to reproduce myself.

What revision are you on?

I can't reproduce this on current central on Windows with Python 3.12.2.

Does the directory <mozilla-central-root>/third_party/python/six/ exist?

[Jeff Muizelaar [:jrmuizel]]

I was actually on an old revision from August 2023. Sorry for the noise.
