golang windows 环境搭建 1.20 ​

sh
##  安装golang安装包
##  设置环境变量 GOROOT    go 安装目录
##  设置GOPATH  默认 是 c:/users/go  可以修改
##  设置代理
go env -w GOPROXY=https://goproxy.cn,direct
go env -w  GO111MODULE=on
##  设置GOPATH   如果环境变量 有则删除之
 go env -w  GOPATH=D:\dev\gostore\practice_projects\go03

##  使用 go mod init  初始化
go mod init 项目名称
##   处理 第三方依赖  下载依赖
go mod tidy
## golang  无法导入 go 
修改 go 源码  
D:\Program Files\Go\src\runtime\internal\sys\zversion.go
添加 下面内容即可
const TheVersion =`go1.20`

golang gin 配置指定版本 1.20 ​
