Hi all,

I got the following error trying to install MoSeq on a Windows machine via WSL2.

(moseq2-app) ~/moseq2-app$ ./scripts/install_moseq2_app.sh

Processing /home/ralphpeterson/moseq2-app

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

hint: See above for details.

It looks like the most recent zipp release requires python >= 3.8. Downgrading zipp (pip install zipp==3.15.0) fixed the issue.

Best,
