Cannot build on M1 Mac

Running Python 3.9 (using Conda)

pip3 install -r requirements.txt

ERROR: Could not find a version that satisfies the requirement PyQt5==5.15.4 (from friture) (from versions: 5.14.0, 5.14.1, 5.14.2, 5.15.0, 5.15.1, 5.15.2, 5.15.3, 5.15.4)
ERROR: No matching distribution found for PyQt5==5.15.4

I'm not sure what to say from this error message: 5.15.4 is listed in the "from versions" list, so it's unexpected to me that it cannot find a matching distribution...

I've been able to test this on a M1 Mac. The situation is that PyQt5 wheels are not provided for arm64 (the architecture for M1). However, it's possible to get everything to work by running a terminal in Rosetta.

I'm closing here since direct support for M1 without Rosetta is not something we'll be able to add to Friture any time soon. Support for M1 was added in Qt6, but the migration to Qt6 is going to require quite some work (see #201)
