Unfortunately, I followed the steps provided in this answer:

> [@Cannot install psychopy through pip on MacOS M2](https://discourse.psychopy.org/t/cannot-install-psychopy-through-pip-on-macos-m2/35873/2):

> For anyone encountering this in future. I ran: brew install hdf5 then export HDF5\_DIR=/opt/homebrew/Cellar/hdf5/1.14.3/ then pip3 install psychopy and this worked! Try to find the location of your H5public.h file to replace the path in the export line

but I keep getting this error on MacOS. I downgraded Python to 3.8.10 as per some online recommendations:  
AttributeError: module ‘pkgutil’ has no attribute ‘ImpImporter’. Did you mean: ‘zipimporter’?  
Then I started getting another error message.  
Full error:

note: This error originates from a subprocess, and is likely not a problem with pip.
