Does anyone encounter the same problem?😭

[alerque]

Your system's version of ctags does not support go.

ctags: Unknown language "go"

You need to use universal-ctags or gotags in order to get usable tag output. If you search though old issues there are a number of places where this is talked about and various combinations that work are mentioned.

@alerque Thanks

[alerque]

Let us know if you still can't resolve this, but make sure your ctags --version shows a copy of Universal Ctags (the Exuberant and BSD editions haven't been updated since before Go lang even existed) or setup gotags specifically and tell tagbar to run that explicitly for go files.

[yedamao]

let g:tagbar_type_go = {
    \ 'ctagstype' : 'go',
    \ 'kinds'     : [
        \ 'p:package',
        \ 'i:imports:1',
        \ 'c:constants',
        \ 'v:variables',
        \ 't:types',
        \ 'n:interfaces',
        \ 'w:fields',
        \ 'e:embedded',
        \ 'm:methods',
        \ 'r:constructor',
        \ 'f:functions'
    \ ],
    \ 'sro' : '.',
    \ 'kind2scope' : {
        \ 't' : 'ctype',
        \ 'n' : 'ntype'
    \ },
    \ 'scope2kind' : {
        \ 'ctype' : 't',
        \ 'ntype' : 'n'
    \ },
    \ 'ctagsbin'  : 'gotags',
    \ 'ctagsargs' : '-sort -silent'
\ }

I add above snippet to my .vimrc, It works fine.

[alerque]

You shouldn't need to do that even. What tag generator are you using?

[yedamao]

I installed

ctags

same problem: Tagbar window is empty on golang file

setting GOBIN in bash env solves problem in my case:

export GOBIN="`go env GOPATH`/bin"
export PATH="$PATH:$GOBIN"
