在安装go插件时，会自动更新很多依赖库文件，都是从Github更新下来，但是因为Github的文件中，多有应用go官网中的文件，导致，因为网络缘故，不能直接下载，导致安装失败，如下：

1、在%GOPATH%\src\ 目录下，建立golang.org 文件夹，并再新建x文件夹。  目录为 "%GOPATH\src\golang.org\x\"

2、完成目录切换后，开始下载插件包：
git clone https://github.com/golang/tools.git tools

3、执行完以后，会多一个tools文件夹。

4、打开vsCode终端，切换到 终端，进入“%GOPATH”目录,执行 

go install github.com/ramya-rao-a/go-outline

go install github.com/acroca/go-symbols

go install golang.org/x/tools/cmd/guru

go install golang.org/x/tools/cmd/gorename

go install github.com/josharian/impl

go install github.com/rogpeppe/godef

go install github.com/sqs/goreturns

go install github.com/golang/lint/golint

go install github.com/cweill/gotests/gotests

go install github.com/ramya-rao-a/go-outline

go install github.com/acroca/go-symbols

go install golang.org/x/tools/cmd/guru

go install golang.org/x/tools/cmd/gorename

go install github.com/josharian/impl

go install github.com/rogpeppe/godef

go install github.com/sqs/goreturns

go install github.com/golang/lint/golint

go install github.com/cweill/gotests/gotests

按此方法，可以安装成功。
