How to set golang gopath

The requirement to set GOPATH is a major issue for Go users who install Go tools for the first time and get the error: "you have to set a Republican Still need to add $GOPATH/bin to their PATH to run the executable initialized by go install to execute go get

Users developing in Go language still need to understand the existence, location and structure of GOPATH.If your GOROOT (where you check Go's source code) is the default GOPATH, the tool will refuse to break your GOROOT using the default GOPATH if no GOPATH is set.If the default doesn't suit you, you may still prefer to set a custom GOPATH.
