前置

從https://studygolang.com/dl下載go1.14.6.windows-amd64.msi安裝即可，安裝路徑選擇默認，安裝完成后會自動幫你配置環境變量不用自己配置了

打開cmd，查看是否安裝完成

這樣就代表已經成功安裝了

用vscode新建一個go文件

vscode會提示你安裝go插件

點擊install all

這時候會安裝失敗

原因你懂的

使用go mod 代理來安裝

https://goproxy.io是一個國內的代理

執行

# 舊版，已廢棄
go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.io,direct

# 新版改成如下鏈接
go env -w GO111MODULE=on
go env -w GOPROXY=https://proxy.golang.com.cn,direct

關閉vscode重新打開，再次點擊install all

成功安裝

開啟go mod 代理后也可以手動安裝

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
