How to reproduce the problem from neovim startup

run :LspInstall cssls or yarn global add cssls call :LspInstallInfo It shows: { cssls = { bin_dir = "/Users/sheldonl/.cache/nvim/lspconfig/cssls/node_modules/.bin", binaries = { ["css-languageserver"] = "/Users/sheldonl/.cache/nvim/lspconfig/cssls/node_modules/.bin/css-languageserver" }, install_dir = "/Users/sheldonl/.cache/nvim/lspconfig/cssls", is_installed = true } }

Actual behaviour

But, when I leave and restart nvim, run :LspInstallInfo, it returns {}, And, no lint, no completion is available

Expected behaviour

When I leave and restart nvim, run :LspInstallInfo, it should returns { cssls = { bin_dir = "/Users/sheldonl/.cache/nvim/lspconfig/cssls/node_modules/.bin", binaries = { ["css-languageserver"] = "/Users/sheldonl/.cache/nvim/lspconfig/cssls/node_modules/.bin/css-languageserver" }, install_dir = "/Users/sheldonl/.cache/nvim/lspconfig/cssls", is_installed = true } } either. And , lint and completion should available

[jerrywang1981]

it looked like cssls was not installed. if installed, when checkhealth it would be shown in health#lspconfig#check section did you verify it in ~/.cache/nvim/lspconfig/cssls ?

[sheldonldev]

yes, I'm sure

 ~/.cache/nvim/lspconfig/cssls  ls -l total 8 drwxr-xr-x 13 sheldonl staff 416 Dec 11 16:37 node_modules -rw-r--r-- 1 sheldonl staff 219 Dec 11 16:37 package.json

[sheldonldev]

and run :LspInstallInfo {}

[jerrywang1981]

https://github.com/neovim/nvim-lspconfig#cssls

did you set it up?

require'lspconfig'.cssls.setup{}

[Julpikar]

I don't know if this problem is the same as yours. I upgraded nodejs version 14 to 15 on windows and get {} message. I rolling back to nodejs 14 and its working fine.

[sheldonldev]

yes, I think I'v set everything like the documentation.

Well, maybe it's the node version, because I use version 15 right now. I will try to roll back later. Thank you @benawas

[mjlbach]

@sheldonldev Did you try rolling back node? Is this still an issue?

[sheldonldev]

@mjlbach not yet, I'll try it this Sunday or Monday

[sheldonldev]

This time I uninstall my node 15.4, it seems no problem.

[mjlbach]

It seems like a lot of language servers are affected negatively by node 15. Is your issue resolved by reverting back then, and can we close?

[sheldonldev]

I'm now using node 14 with nvm. It seems OK now. Sure we can close it. Thank you.

[mjlbach]

Thank you! If you can isolate the issue to something in particular one of the configuration scripts is doing, file another issue. Otherwise if this is an upstream issue it should be reported to the respective language server.

[sheldonldev]

Alright. Thank you!
