vscode安装go相关插件失败或go get安装第三方包失败

比如安装下面第三方包

C:\Users\xxx>go get github.com/denisenkom/go-mssqldb
go get github.com/denisenkom/go-mssqldb: module github.com/denisenkom/go-mssqldb: Get "https://proxy.golang.org/github.com/denisenkom/go-mssqldb/@v/list": dial tcp 172.217.24.17:443: 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.

或vscode安装下面的失败

解决方法

• 从GitHub上clone下来安装
• 最省事的：改GOPROXY代理环境变量为https://goproxy.cn，或其他代理地址
