代码：

package main

import "github.com/gin-gonic/gin"

func main() {
    r := gin.Default()

    r.Handle("GET", "/ping", func(context *gin.Context) {
        context.JSON(200, gin.H{
            "message": "pong",
        })
    })

    r.Run() 
}

错误：

C:\Users\hxia\go\Gin>go run main.go
main.go:3:8: no required module provides package github.com/gin-gonic/gin; to add it:
        go get github.com/gin-gonic/gin

描述：

随着 go get 下载 Gin 模块，它显示失败并出现连接错误，检查它似乎配置正确的环境：

set GO111MODULE=on
set GOPROXY=https://goproxy.cn,direct

将 GOPROXY 更改为https://goproxy.io.direct它也失败了。

我在visual studio中配置了一个http_proxy，然后挂起代理是否有问题，所以去掉代理，把代理从HTTP改成HTTPS，都失败了。

有没有高手可以指出这个问题，我该如何解决这个问题？非常感谢！！
