[SOLVED] Polybar not building

I'm trying to build polybar and getting some python errors and I can't seem to figure out why. I have all of the dependencies for polybar.

Code:

make

[  1%] Built target doc_man
[  1%] sphinx-build html: see doc/builder-html.log

This is for i3-wm. Searching the webs seems like other people got polybar to work but they're 4 year old threads.

this means usually some part of your build system is outdated (or just incompatible with some other parts).
Let's say the python version you use (3.11) contains a modified Expression class, not the one used by polybar. But obviously it is just a wild guess.

Something went wrong with the build. I ran into multiple issues trying to compile other programs. Rebuilt the system and everything is working.
