How Can I Retrieve the GOPATH from within a Go Program?

Retrieving GOPATH from Code in Go

To access the current GOPATH from within a Go code block, use os.Getenv:

import (
    "fmt"
    "os"
)

func main() {
    fmt.Println(os.Getenv("GOPATH"))
}

As described in the documentation:

Getenv retrieves the value of the environment variable named by the key. It returns the value, which will be empty if the variable is not present.

Note for Go 1.8 :

In Go 1.8 and later, the default GOPATH can be accessed via go/build:

import (
    "fmt"
    "go/build"
    "os"
)

func main() {
    gopath := os.Getenv("GOPATH")
    if gopath == "" {
        gopath = build.Default.GOPATH
    }
    fmt.Println(gopath)
}
