Both GoSublime and vim-go tells me that GOPATH isn't set, however I've already done this.
my ~/.bashrc:
export GOPATH=$HOME/gopath
export PATH="$PATH:$GOPATH/bin"
and I can use go get to install gocode to my ~/gopath/bin but it prints that: ...:/home/myusrname/gopath/bin: No such file or directory for ~$ $PATH
~$ $PATH
is trying to execute your $PATH string, i.e. it's equivalent to writing the contents of the $PATH variable into the console and pressing enter. That results in the error you're seeing.
What you want is
~$ echo $PATH
finally i got it: i have to open gvim through shell with $GOPATH set - -!
You can try to start gvim with the command: bash -lc gvim
It then starts gvim with the settings in your .bashrc file.
This is from https://github.com/fatih/vim-go/issues/468
In my case, I added GOPATH in my .profile
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin
And restart my Unbuntu 16.04
Then for my vim-go, I installed the vim-go by the following command in gvim
:GoInstallBinaries
