:GoInstallBinaries must be ru-run for every new invocation of vim

[PaulForgey]

Behavior

vim-go: could not find 'guru'. Run :GoInstallBinaries to fix it.
Although $GOPATH/bin/guru does indeed exist, issuing :GoInstallBinaries fixes the issue but only for the current VIM session. New instances of vim go through the same problem.

Steps to reproduce:

1. vim
2. :GoDef (or any :Go command)
3. observe error vim-go: could not find 'guru'. Run :GoInstallBinaries to fix it.
4. :GoInstallBinaries
5. :GoDef (now works)
6. ':q'
7. vim
   8.: GoDef
8. observe error
9. loop back to step 4.

Configuration

:echo $GOPATH
/Users/paulf/src/go
:!ls $GOPATH/bin
asmfmt gocode gogetdoc golint gorename guru motion
errcheck godef goimports gometalinter gotags impl

Add here your current configuration and additional information that might be
useful, such as:

• vimrc you used to reproduce
  call plug#begin('~/.vim/plugins')

Plug 'fatih/vim-go', { 'tag': 'v1.10' }

call plug#end()

Hi @PaulForgey

Vim reads the binaries from your PATH, if it's there you should be covered. Seems like it's not the case. :GoInstallBinaries is just a helper command, it's not required and you should not call it everytime. Please be sure you installed them correctly. Thanks

I ran into this embarrassing situation today, and I found that my $GOPATH/bin is not in the $PATH. In order to make several go projects use go-vim smoothly, I think move the binaries using by vim-go(e.g. guru) to $GOROOT/bin

also, better to double check that a project being edited form go src e.g: vim $GOPATH/src/github.com/testing/test.go

FYI for those who have this issue, and go is in their PATH. It is possible that the deps wont build either because of an issue with the dep itself, or more likely, your version of go is out of date, or its version is incompatible with one of the deps.

example: If you install golang-go in debian stretch using apt, golang will likely be too old. You are always suggested to install from the golang downloads page.

Env set $GOBIN and :GoInstallBinaries fix it.

In my case, I had to add $GOROOT to $PATH to resolve this issue.

export PATH=$GOROOT:$GOROOT/bin:$PATH

Upon checking for PATH, I found out that GOROOT was not included. After adding it, vim-go stopped complaning about missing gopls.

Helpful commands:

# Check for env GOROOT  that is effectively in use
go env GOROOT

# Echo PATH variable and then print each one in separate line as shown in screenshot below
echo $PATH| tr ':' '\n'|sort -rn
