Error Message Go Unrecognized import path

Saya menggunakan Linux Ubuntu dan golang versi 1.8 ya guys. Disana coba perhatikan GOPATH dan GOROOT. gopath dan goroot tidak boleh sama, karena secara persepsi gopath itu tempat kita menyimpan source development go, sedangkan goroot adalah untuk membaca engine golangnya agar script yang dituliskan dengan bahasa golang yang disimpan didalam GOPATH bisa di execute.

Apabila kalian error seperti ini dibawah ini :

package crypto/subtle: unrecognized import path “crypto/subtle” (import path does not begin with hostname)
package encoding/gob: unrecognized import path “encoding/gob” (import path does not begin with hostname)
package encoding/hex: unrecognized import path “encoding/hex” (import path does not begin with hostname)

Kalian harus perbaiki, untuk settingan go env GoPATH dan GoROOT saya adalah :

export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin

Semoga bermanfaat.
