准备工作

windows系统

添加环境变量GOPROXY

GOPROXY=https://goproxy.io

查看是否设置成功

 在goland里面设置

linux系统

 引入环境变量

export GOPROXY=https://goproxy.io

 goland创建项目

不在GOPATH目录下。在demo目录下创建main.go。

main.go

package main

import (
	"fmt"
	"net/http"
	"rsc.io/quote"
	"github.com/labstack/echo"
)
func main()  {
	fmt.Println("hello")
	fmt.Println(quote.Hello())
	e := echo.New()
	e.GET("/", hello)
}

func hello(c echo.Context) error {
	return c.String(http.StatusOK, "Hello, World!")
}

 go mod init

要使用go modules，需要在需要项目目录下执行

// go mod init 项目名称
go mod init demo

 执行完后会生成go.mod文件

module demo

go 1.12

require (
	github.com/labstack/echo v3.3.10+incompatible // indirect
	github.com/labstack/gommon v0.2.9 // indirect
	golang.org/x/crypto v0.0.0-20190701094942-4def268fd1a4 // indirect
	golang.org/x/text v0.3.0
	rsc.io/quote v3.1.0+incompatible // indirect
)

replace golang.org/x/text => github.com/golang/text v0.3.0

go test all

 执行go test all，就会下载所有相关依赖

go test all

go test all
go: finding github.com/robfig/cron v1.2.0
go: downloading github.com/robfig/cron v1.2.0
go: extracting github.com/robfig/cron v1.2.0

go: extracting github.com/davecgh/go-spew v1.1.1

 相关依赖下载完以后，运行main.go就可以了。

go.sum

go run main.go

生成go.sum文件
