[开发工具]golang使用vscode gin Web开发配置

go的代理设置参考https://goproxy.io/zh/

• 下载安装gin
  go get -u github.com/gin-gonic/gin

• 报错 cannot find module providing package github.com/gin-gonic/gin: working directory is not part of a module

• 解决
  $ go mod init gin
  $ go mod edit -require github.com/gin-gonic/gin@latest
  $ go mod tidy
