Vim-go: Can't install gogetdoc using :GoInstallBinaries

[timfayz]

I'm trying to make vim-go work properly, but I stack at GoInstallBinaries step.

Steps to reproduce:

1. Add line Plug 'fatih/vim-go'
2. Run :PlugInstall using vim-go plugin installer
3. Run :GoInstallBinaries
4. vim version - 7.4
5. vim-go version - master branch
6. go version - 1.6.2

Here are the error after running :GoInstallBinaries:

vim-go: gogetdoc not found. Installing github.com/zmb3/gogetdoc to folder /home/timur/code/third-party/bin/

UPDATE

After updating Go to the latest version _correctly_ (the previous errors was due to incorrect updating) and running :GoInstallBinaries - nothing happens. I still get errors like guru/gogetdoc: command not found when I try to use commands GoDoc, GoDef etc. What's wrong?

SOLVED

It was needed to add $GOPATH/bin directory to $PATH variable.

#~/.bashrc
...
export GOPATH=$HOME/code
export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin
...
