下载echo框架

在项目根目录里(D:Gowwwsrcecho_one) 建新 main.go

package main

import (
   "net/http"
   "github.com/labstack/echo"
)

func main() {
   e := echo.New()
   e.GET("/", func(c echo.Context) error {
      return c.String(http.StatusOK, "Hello, World!")
   })
   e.Logger.Fatal(e.Start(":8001"))
}

在cmd里,cd到项目根目录里

D:Gowwwsrcecho_one>set GO111MODULE=on
D:Gowwwsrcecho_one>go mod init
D:Gowwwsrcecho_one>go mod tidy

D:Gowwwsrcecho_onego.mod里

module echo_one

go 1.12

require (
   github.com/labstack/echo v3.3.10+incompatible
   github.com/labstack/gommon v0.3.0 // indirect
   golang.org/x/crypto v0.0.0-20191108234033-bd318be0434a // indirect
)

replace golang.org/x/crypto v0.0.0-20191108234033-bd318be0434a => github.com/golang/crypto v0.0.0-20191108234033-bd318be0434a // indirect

再cmd里再执行命令

D:Gowwwsrcecho_one>go mod download

此时已经安装好echo了

cmd里启动运行一下

D:Gowwwsrcecho_one>go run main.go
