As the author says:
nREPL needs to create .nrepl-port file
How do you go about installing and using an emacs package that expects to have write access to it’s install directory?

I got a chance to look at this again today and I got closer… now I’m unsure if there’s a remaining elisp error or an nrepl error.
I basically just said “nrepl use the /tmp” directory but that broke something else, see: https://github.com/codygman/hci/commit/ddd9cf8dbb9c5659f54f3e32db84dac9fd30df5e#diff-6368190673f1bdd962cb26e3712b49eeR922
That’s generally the solution – you have to change the directory to something writeable outside the nix store,
If the port-file is something that can be prebuilt, you can also pre-generate it also.
