**1.安装golang**  
下载对应系统的Go安装包  
[https://studygolang.com/dl][https_studygolang.com_dl]

**2.安装完之后验证**

➜   go version
    go version go1.12.2 darwin/amd64

**3.设置GO111MODULE环境变量**

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.在你喜欢的目录创建测试项目**

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

在项目目录下执行

go mod init hello

会生成一下文件go.mod

➜   cat go.mod 
    module hello
    
    go 1.12

运行demo.go

go run demo.go
      golang122 go run demo.go

该过程自动把依赖下载到$GOPATH/pkg/mod  
![demo][]  
![golang][]  
可以看到，多生成了一个文件go.sum  
![ll][]

go.mod的内容会多了以下内容  
![demo][demo 1]  
go.sum的内容  
![yes][]  
end
