吧里吧唧，首先在你源码目录创建一个go.mod，或者直接把下面的go.mod替换掉，go.mod
里面的test改成你项目的名字。
接下来就是一堆谷口翻墙替换的镜像。
如下图设置
/Users/yanlingbo/go.mod
最后是层级目录要改，改成 模块名/同级目录
如下
最后是 编辑器开启
开启go mod linux下：
export GO111MODULE=on
win下：
set GO111MODULE=on
这样你就脱离gopath的约束了，只是pkg最后都在gopath 最后安利下：分布式游戏框架，大家支持下 https://studygolang.com/p/gonet
有疑问加站长微信联系（非本文作者））
试一下
/Users/yanlingbo/go/myserver/src/go.mod
不翻墙能下载的了那些被墙的包？不可能去github上down下来替换吧
Git config --global http.postBuffer 1524288000 git又是rpc错误，git仓库台小了，可以的
附上翻墙替换的 module gonet
