Bug: Unable to successfully complete the post-install step. about coc.nvim

[chemzqm]

@megalithic https://github.com/neovim/node-client need to have a new release.
Sorry for the unconvince.

[megalithic]

Could you give more details? Is there a PR that needs to be merged, or is there something specific that they know about that needs to be fixed but haven't documented it anywhere? Are you running a patched version locally? Would love to know more. Thanks so much!

[chemzqm]

It's already merged neovim/node-client@c1e940b
just need to publish a new release to npm.

[chemzqm]

BTW, coc currently only have some advanced language support for typescript (more language and LSP support is coming), so it might not fit your requirement.

[megalithic]

thanks for the info @chemzqm!

[megalithic]

@chemzqm might be worth adding a note to the Troubleshooting section to mention about the version of the neovim-node-host client needs to be updated past 4.1.0 to work with your plugin, which i still desperately want to try! :)

[megalithic]

@chemzqm I was able to complete the post-install process, yay! However, coc.nvim is never able to register with the plugins registry, e.g., it continually says there was a problem initializing and to run :UpdateRemotePlugins and restart. Running :checkhealth shows the following for coc.nvim:

health#coc#check
========================================================================
  - OK: Environment check passed
  - ERROR: service could not be initailized
    - ADVICE:
      - You may not have neovim package installed correctly,
      - check out https://github.com/neovim/node-client#debugging--troubleshooting

and the node-host health check shows:

## Node.js provider (optional)
  - INFO: Node.js: v8.11.3
  - INFO: Neovim node.js host: /Users/me/.n/bin/neovim-node-host
  - OK: Latest "neovim" npm package is installed: 4.2.0

Any thoughts?

[chemzqm]

Did you run :UpdateRemotePlugins after npm install? And what's the result?

[megalithic]

@chemzqm yes, repeatedly, with no specific error output, other than seeing that the plugin isn't registered with the node host. I know plugins can register with the node host because if I switch back to deoplete + nvim-typescript; nvim-typescript registers with the node host, and deoplete with the python3 host.

[chemzqm]

Check your ~/.local/share/nvim/rplugin.vim, is that coc registered correctly?

According to https://github.com/neovim/node-client#debugging--troubleshooting, you can set NVIM_NODE_LOG_LEVEL to error and NVIM_NODE_LOG_FILE to a log file, and get the output from the log file.

[megalithic]

~/.local/share/nvim/rplugin.vim output:

" node plugins


" python3 plugins
call remote#host#RegisterPlugin('python3', '/Users/me/.dotfiles/nvim/plugged/deoplete.nvim/rplugin/python3/deoplete', [
      \ {'sync': v:false, 'name': '_deoplete_init', 'type': 'function', 'opts': {}},
     \ ])


" ruby plugins


" python plugins

i'll see if i can't get logging to occur from the link you provided and will report back.

[chemzqm]

Looks like coc is not registed, the output of :UpdateRemotePlugins should contains:

[megalithic]

Exactly! However, we don't know why it's not able to register. I'm not getting any logging from your plugin or from the node client either. Are you able to remove your plugin completely and reinstall from GitHub without issues?

[chemzqm]

@megalithic just tried using [email protected] from npm, no issue found.

[chemzqm]

There should be something in your log file, try set environment variable NVIM_NODE_LOG_LEVEL to debug

[megalithic]

thanks for your help @chemzqm, i'll keep trying and report back once i have more information. :/

[chemzqm]

I got the reason, I can fix that.

[megalithic]

oh excellent! thanks so much!

[chemzqm]

To avoid https://github.com/sourcegraph/javascript-typescript-langserver get high CPU usage, I add rplugin folder to my .gitignore and forget to remove that.
