Slimv not starting Swank server on NeoVim


I’ve started to learn Common Lisp and decided to use Slimv as an interactive environment in NeoVim. However when I opened up a .lisp file and tried to evaluate the expression using ,e it started “Starting SWANK server…” and after a few seconds it returned the error SWANK server is not running.

I understand that I need to start Swank server manually and separately, but I’m not sure how to do that. In Slimv’s documentation, it says I need to specify something like this:

let g:slimv_swank_cmd =
    '! xterm -e sbcl --load /usr/share/common-lisp/source/slime/start-swank.lisp &'

But I don’t know where to find that start-swank.lisp due to the way Vim plugins are installed in NixOS. Could someone please help me with this? Thank you!
