关于go开发目录的结构这里不做过多解释，之前已经说过了
进行如下命令进行目录切换：

cd %GOPATH%\src\github.com\golang

我这里的GOPATH是在D:\go_project

如果src目录下面没有github.com\golang请自行创建
完成目录切换后，开始下载插件包：

git clonehttps://github.com/golang/tools.gittools

当下载完成后，你会发现%GOPATH%\src\github.com\golang多了一个tools目录

需要把tools目录下的所有文件拷贝到%GOPATH%\src\golang.org\x\tools下，如果没有自行创建

当然如果你是windows环境，如果你当前是在%GOPATH%\src\golang.org\x\tools

目录下，你可以直接使用如下命令进行拷贝：

xcopy /s /e %GOPATH%\src\github.com\golang\tools

关于这个命令的使用可以具体百度查看，如果对该命令不熟悉就手动拷贝,直接将你下载的tools目录下的所有文件拷贝到%GOPATH%\src\golang.org\x\tools目录下
经过多次测试，插件中有几个其实不用翻墙或其他方法就可以安装成功：

github.com/nsf/gocode

github.com/uudashr/gopkgs/cmd/gopkgs

github.com/fatih/gomodifytags

github.com/haya14busa/goplay/cmd/goplay

github.com/derekparker/delve/cmd/dlv

下面安装无法安装的插件

开始安装：

切换到GOPATH目录下，执行相关的go install 命令

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

这样vscode下go开发需要安装的插件都已经安装成功
总结
