1import (2func main() {3 obj.MethodType()4 fmt.Println("Hello, playground")5}6import "fmt"7type Utils struct {8}9func (u *Utils) MethodType() {10 fmt.Println("MethodType")11}12I have a package utils with a class Utils and a method MethodType. I want to use this method in another package main. I have tried the code below but it doesn’t work. I am getting the following error: cannot find package “utils” in any of: /usr/local/go/src/pkg/utils (from $GOROOT) /Users/username/go/src/utils (from $GOPATH). I have tried adding the path to the GOPATH but it still doesn’t work. How can I use the method in another package?
