Hello! Hm, weird. The :checkhealth, logs and :LspInstallInfo outputs sort of contradict each other tbh. Are you sure luarocks is executable in the same shell session that you launch neovim in? Will have to look deeper into this next time I'm at a Windows PC.
Yeah, weird.
I can run !luarocks in neovim cmdline and get the same output so I guess shell session is not a problem.
EDIT: isn't there a need to append .bat (or in some cases .cmd) for Windows? Seems like I can run it using both luarocks.bat and luarocks.
EDIT: isn't there a need to append
.bat(or in some cases.cmd) for Windows? Seems like I can run it using bothluarocks.batandluarocks.
Yeah, although this really depends on the PATHEXT environment variable. Note however that libuv (which neovim and this plugin uses to spawn processes) does not respect PATHEXT. From just reading the online docs I assumed luarocks was installed as a binary (.exe) on Windows, but if it's a .bat script we probably need to adjust things
I might be wrong but seems like .luarocks always comes as a .bat script for Windows
EDIT: luarocks on scoop comes as an exe.
Could you see if branch fix/luarocks-windows (#731) fixes this?
Yes, it works. I did the same locally.
Just wondering if the same should be added to lua\nvim-lsp-installer\health\init.lua:13 as its done for other package managers there? healthcheck still fails at luarocks for me.
Sadly it still doesn't work for me but its installing correctly!
I had to also add cmd for server setup command, like this:
cmd = {
'teal-language-server.bat'
},...otherwise I will get:
Spawning language server with cmd: `teal-language-server` failed. The language server is either not installed, missing from PATH, or not executable.
Now I'm stuck at:
[ERROR][2022-05-28 23:32:08] .../vim/lsp/rpc.lua:420 "rpc" "teal-language-server.bat" "stderr" "C:\\Users\user\hererocks\\bin\\lua.exe: error loading module 'tealls.util' from file 'C:/Users\user\AppData/Local/nvim-data/lsp_servers/teal_ls/share/lua/5.1/tealls\\util.lua':

...and it looks like its a problem with language server itself, maybe I'm wrong but looks like there is // operator used (divide floor), while its not acceptable in lua 5.1.
But I guess that's all out of context of this issue.
Just wondering if the same should be added to
lua\nvim-lsp-installer\health\init.lua:13as its done for other package managers there?healthcheckstill fails atluarocksfor me.
Ah good catch, fixed in #732.
I had to also add
cmdfor server setup command, like this:
This should be fixed in lspconfig then! If you'd like you can fix this yourself and open a PR there, see ltex for reference!
@EtiamNullam How did you install Luarocks? I'm struggling a bit with finding a functional one
I also had a problem with finding a good one, ended up with https://github.com/mpeterv/hererocks
EDIT: @williamboman as lua51 was just added to ScoopInstaller/Versions I suggest using scoop (add bucket versions )
EDIT2: if you want to use hererocks better use this one as its maintained: https://github.com/luarocks/hererocks, IMO better to use scoop
