coc-ccls not working

[ghost]

Hi,

I installed coc.nvim using vim plug with the branch/master setting. It works well for lots of languages but when I installed coc-ccls it shows an error every time I start nvim:

[coc.nvim] Unable to load global extension at /home/psd/.config/coc/extensions
/node_modules/coc-ccls: main file ./lib/extension.js not found, you may need t
o build the project.

I did what it told me to do and went into ~/.config/coc/extensions/node_modules/coc-ccls and deleted the package lock and all its node modules, and then ran:

yarn install --frozen-lockfile

And it generated lots of errors LoL:

Result from CocInfo

versions

vim version: NVIM v0.4.3
node version: v13.2.0
coc.nvim version: 0.0.78-475932ddf5
coc.nvim directory: /home/psd/.local/share/nvim/plugged/coc.nvim
term: xterm-256color
platform: linux

I am running Void Linux, but this problem also appears on my Linux Mint laptop too. I think the coc-ccls extension is out of date and no longer compatible with some of the newer node modules you started using. I would fix the extension source code myself, but I'm a C hacker and don't know anything about javascript or typescript LoL

Thanks,
Phil

That extension on npm is broken now, you can use vim-plug to install it from github.

[lcksk]

cd ~/.config/coc/extensions/node_modules/coc-ccls
ln -s node_modules/ws/lib lib

Does this work for you ?

It appeared the author abandoned it, so I did too. I need to do some C development on a Raspberry PI, but neovim is laggy on that device, and when you add in code completion it is just too slow to be useful, so I decided to use CLion on my PC because it has excellent remote deployment capabilities ...

[elland]

@rolandjon thanks, that did it for me!

[linweilin]

cd ~/.config/coc/extensions/node_modules/coc-ccls
ln -s node_modules/ws/lib lib

Does this work for you ?

thanks, that did it for me!

I just hit this missing symlink on windows. Fixed locally much the same way. In powershell as admin:

cd .config\coc\extensions\node_modules\coc-ccls
New-Item lib -ItemType SymbolicLink -Value .\node_modules\ws\lib\

cd ~/.config/coc/extensions/node_modules/coc-ccls
ln -s node_modules/ws/lib lib

Does this work for you ?

That worked for me! Thanks!

[gerazov]

This should be in the README 🙂

[tony]

cd ~/.config/coc/extensions/node_modules/coc-ccls
npm i
npm run build

For some reason listing coc-ccls in my config by itself isn't enough to do the trick.

[oblitum]

@tony it's what the thread has been saying all along it seems (extension is broken).

Life is easier with coc-clangd.

[oblitum]

If extension is dead, and wish to keep with ccls, I just configure the server and not use the extension, unless there's a newer one.

[tony]

How goes it @oblitum!

I will take a look at coc-clangd.

[oblitum]

@tony hey 👍

[tony]

@oblitum Moved over, things are much faster now. Surprised by how good clangd is

[oblitum]

@tony yup, the main argument for ccls when it was out was due to clangd's lack of cache, it now has cache and all that.

[Realtyxxx]

hey！ but how to configure with coc-clangd ,my clangd always gives me warning when it comes to c++11 standard

[AlexvZyl]

Thanks for the clangd suggestion.
