一、下载网址

1.官网：golang.org
2.国内下载：studygolang.com/dl

下载好双击运行就可以了

二、环境变量的配置

cd /usr/local/go

2.配置环境变量

lishuo@李硕的MacBook Pro:/usr/local/go
$ vim ~/.bash_profile

里面填写如下内容

# 分别在 .bash_profile 和 .zshrc 文件后面追加go的环境变量配置
# 说明：GOPATH表示go的工程根目录，之后的go程序均写在该目录下
 
# Go
export GOPATH=/Users/lishuo/Code/goRoot
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOBIN
# Go END

3.重新加载配置信息

lishuo@李硕的MacBook Pro:/usr/local/go
[127] $ source ~/.bash_profile
[128] $ source  ~/.zshrc

4.查看是否有版本信息

$ go version
go version go1.18.1 darwin/amd64

三、更换国内镜像下载

国内镜像网站：goproxy.cn/，按照步骤操作即可

lishuo@李硕的MacBook Pro:/usr/local/go
$ go env
