用vscode开发go的时候，安装go包报错：connectex: A connection attempt failed because the connected party did not

用vscode开发go的时候，安装go包报错，就找到了这篇文章，改一个配置，设置代理就好了。记录一下

一、问题

用 go build 创建项目，拉取go第三方扩展包的时候报如下错误：

dial tcp 34.64.4.113:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

二、分析

查看 GOSUMDB 的配置

go env

• 1

最后是因为：set GOSUMDB=sum.golang.org

把它关掉

go env -w GOSUMDB=off

• 1

代理推荐

go env -w GOPROXY=https://goproxy.cn,direct

• 1

再次执行命令 go build，成功~
