[Go] 使用go mod安裝beego

須要go升級到1.12或以上

mkdir gomodtest
cd gomodtest
go mod init gomodtest

建立一個server.go

package main
import "github.com/astaxie/beego"
func main() {
    beego.Run()
}

go run server.go
自動查找依賴而且下載依賴的包到$GOPATH/pkg/mod/github.com/astaxie
go run server.go

生成go.mod文件

module gomodtest

go 1.13

require (
    github.com/astaxie/beego v1.12.0 // indirect
    github.com/shiena/ansicolor v0.0.0-20151119151921-a422bbe96644 // indirect
