Languageclient-neovim: Os { code: 13, kind: PermissionDenied, message: "Permission denied" }

[willdavidow]

Everything was working perfectly, I was getting inline error reporting in my JavaScript files (coming from the javascript-typescript-stdio language server), the Language Server was auto-starting and the plugin gave me "no language server installed for ____" in the case of a filetype with no language server - which was expected and desired...

...then I ran some VIM package updates (I'm using minpac) and restarted my machine; now I'm seeing this error when attempting to run :LanguageClientStart:

Os { code: 13, kind: PermissionDenied, message: "Permission denied" }

Has anyone seen this issue and/or do you know a way to fix it? I have tried re-installing the plugin, adding the plugin path (manually) to my $PATH (in my .zshrc and rtp in my .vimrc). I've also run chmod -R +X bin inside the LanguageClient-neovim plugin directory.

I can't get it working again...

Can you change to plugin directory and run

bin/languageclient --version

[willdavidow]

languageclient 0.1.54 (756e6932a02d03308689b2bd8dc31fef2736c4a3 2018-03-31T02:31:14.896173Z)

+1 am also seeing this on macOS.

Please attach log files here. I cannot reproduce this issue locally.

[TylerLeonhardt]

@autozimu can you give some instructions on where the logs are?

Unfortunately, those have nothing useful in them :( (p.s. those are stale logs. I was opening a PowerShell file)

[TylerLeonhardt]

Interestingly, nvim-completion-manager had a strange permission related error: cannot open .git/FETCH_HEAD: Permission denied

I fixed it by following this StackOverflow: https://stackoverflow.com/questions/13195814/trying-to-git-pull-with-error-cannot-open-git-fetch-head-permission-denied

[TylerLeonhardt]

I updated my mac which included an update and it works again.

[willdavidow]

@autozimu: I'll leave this issue open for you to close or mark as something to investigate, but I just had a Mac OS update and XCode update that restarted my machine and similar to @tylerl0706 this fixed/got rid of my issue here.

So strange..

[autozimu]

I cannot investigate without local reproduction or useful logs.

[willdavidow]

Makes sense - my logs are the same as the ones posted above... If I ever have this issue again, I'll post here.

[kyrisu]

Just heads up - if anyone is experiencing this issue check your log files permissions.
I must have run nvim as root (sudo) cause this is what I had:

$ ls -l /tmp/Lang*
-rw-r--r-- 1 root root 407 May 28 11:33 /tmp/LanguageClient.log
-rw-r--r-- 1 root root   1 May 28 11:33 /tmp/LanguageServer.log

Removing log files solved the issue for me.

[faultysegment]

Just here to confirm that I had the same issue, Language Servers log had root as an owner.
After they were deleted an issue was resolved
