Go版本管理历史 ## Go版本历史  GOPATH /2012/go 1.0  goven GOINSECURE: 可以通过HTTP获取的module列表 ## GO111MODULE • on或者未设置：启用module模式，即使go.mod不存在 • off: 禁用module模式，使用GOPATH模式 • auto: go.mod存在或者任意的父目录存在，启用module模式 ## go-proxy & private modules ## • 代理所有的module GOPROXY=https://proxy example.com ## 创建一个项目 • 创建go.mod • go mod init: 如果在GOPATH下创建 • go mod init: 如果在GOPATH,但是已经有一个仓库比如github.com/xxx/xxx关联了它 • go mod init path: GOPATH外的裸项目 • go mod tidy 自动创建依赖 • go mod download 下载依赖
