Don't post the install location for a directory outside of the GOPATH error when running "go get"

Simple Go project with external dependency:

import (  
        "fmt"  
        "html"  
        "log"  
        "net/http"  
        "github.com/gorilla/mux"  
)

      

        
        
        
      

    

My path works fine for other tasks like run, build, etc .: GOPATH="/home/racar/go"

But when I try to get the external package with the "get get" command, I got this error:

"go install: no install location for directory ... outside of GOPATH"

Edit: I set my PATH to ~ / .bashrc: export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
