Nvim-treesitter troubleshooting

Error executing lua Failed to load parser: uv_dlopen

This likely means you'll need to recompile the treesitter parsers.
I mostly encounter this while using a nvim provided by a nix environment.
This makes sense, since I likely built this extension using the system or an alternate nvim version.

Uninstalling/Reinstalling (recompiling) the parser should resolve the issue.
