Can't get OpenCache to work

[nachiket]

When I try to run OpenCache on the default config files, I'm getting this error:

Can you check your amaranth version? I had used version 0.3 when I was working on OpenCache. This might be caused by some incompatibility. It may work if you switch to version 0.3.

[nachiket]

That worked. I needed pip3 install amaranth==0.3 amaranth-yosys. Maybe edit requirements.txt for this?

[nachiket]

Looks like amaranth=0.3 now has some weird packaging issues. What might it take to upgrade amaranth version? I can't get it to work with newer versions.

Please use pip<24.1 if you need to use this version.

[pradyungn]

Install pip==24.0 to fix the above error. Just ran into this myself. This may be an issue to file with amaranth, not opencache.
