Press ENTER or type command to continue

Other Things are working fine!
Maybe its just that i did something stupid.

Same here, for what it's worth.

Otherwise, great setup - this may very well replace my homegrown config! Simple and effective.

You probably have files under ~/.local/share/nvim you can just move that folder out to test

[bdillahu]

I had removed all of ~/.local/share/nvim before loading this config... so whatever is there it created.

But I just re-ran it and checkhealth is now working - not sure what changed. I had tried several times yesterday, but now it's happy, so...

Thanks!

The fix for me was to do the following:

First run nvim twice to make sure everything is installed and tree-sitter has compiled everything.

Then start nvim and do the following:

:LspInstall pyright

You can install any LSP server you want, but I use Python so I did pyright.

After I did that I could then do :checkhealth

I tested this in the Docker container I created to try this out. See #8

Alright I figured out everything!
This error occurs because npm or LSP is not installed.
Make sure you have npm, node and cargo installed on your system.
I found these prerequisites from lunarvim's Documentation

On Arch install following packages:

sudo pacman -S npm nodejs rust

Also Resolve EACCES permissions when installing packages globally to avoid error when installing

Then run nvim and install a language server of your choice

:LspInstall sumneko_lua

I am installing LSP for lua here.
Or run :LspInstallInfo for list of all available LSPs.

Chris should add a prerequisites section in README.md
