go mod使用

go 1.12之后 GO111MODULE=auto默认为这个，只要不在GOPATH/src下面

mkdir akin
vi demo.go
package main

import "github.com/astaxie/beego"

func main() {
    beego.Run()
}

初始化：
go mod init akin
go run demo.go    //就可以运行
如果在国内，可能上步不成功，可以使用
export GOPROXY=
go run demo.go    //再运行试一下，应该没问题

[root@FH21_TestServer akin]# go run demo.go
