1.安裝golang
下載對應系統的Go安裝包
https://studygolang.com/dl

2.安裝完之後驗證

➜   go version
go version go1.12.2 darwin/amd64

3.設置GO111MODULE環境變量

 export GO111MODULE=auto

➜   echo $GO111MODULE
auto

go env
GOARCH="amd64"
GOBIN="/usr/local/go/bin"
GOCACHE="/Users/xinzhiyun/Library/Caches/go-build"
GOEXE=""
GOFLAGS=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GOOS="darwin"
GOPATH="/Users/xinzhiyun/112-k8s"
GOPROXY=""
GORACE=""
GOROOT="/usr/local/go"
GOTMPDIR=""
GOTOOLDIR="/usr/local/go/pkg/tool/darwin_amd64"
GCCGO="gccgo"
CC="clang"
CXX="clang++"
CGO_ENABLED="1"
GOMOD="/Users/xinzhiyun/golang122/go.mod"
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
PKG_CONFIG="pkg-config"
GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fdebug-prefix-map=/var/folders/71/rt2h8r3n7_72_hzqbln63df40000gn/T/go-build382191781=/tmp/go-build -gno-record-gcc-switches -fno-common"

4.在你喜歡的目錄創建測試項目

➜  cat demo.go 
package main

import "github.com/astaxie/beego"

func main() {
    beego.Run()
}

在項目目錄下執行

go mod init hello

會生成一下文件go.mod

➜   cat go.mod 
module hello

go 1.12

運行demo.go



go run demo.go

該過程自動把依賴下載到$GOPATH/pkg/mod

可以看到，多生成了一個文件go.sum
