vscode安装go插件失败

前置

从https://studygolang.com/dl下载go1.14.6.windows-amd64.msi安装即可，安装路径选择默认，安装完成后会自动帮你配置环境变量不用自己配置了

打开cmd，查看是否安装完成

这样就代表已经成功安装了

用vscode新建一个go文件

vscode会提示你安装go插件

点击install all

这时候会安装失败

原因你懂的

使用go mod 代理来安装

https://goproxy.io是一个国内的代理

执行

# 旧版，已废弃
go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.io,direct

# 新版改成如下链接
go env -w GO111MODULE=on
go env -w GOPROXY=http://proxy.golang.com.cn,direct

关闭vscode重新打开，再次点击install all

成功安装

开启go mod 代理后也可以手动安装

go get -u -v github.com/mdempsky/gocode
go get -u -v github.com/uudashr/gopkgs/v2/cmd/gopkgs
go get -u -v github.com/ramya-rao-a/go-outline
go get -u -v github.com/acroca/go-symbols
