注意：该演示环境是windows环境，linux和mac环境操作思路一样
vscode中有很多go的相关插件，非常好用如下：
gocode
gopkgs
go-outline
go-symbols
guru
gorename
gomodifytags
goplay
impl
godef
goreturns
golint
gotests
dlv
但是由于各种原因，这些插件无法安装，甚至你翻墙之后发现也还是无法安装，加上最近翻墙被限制的这么严格，所以总结了如下方法，让你在不翻墙的情况下还能将这些插件安装成功，下图是我直接通过vscode安装提示的错误：
貌似运气还不错，还安装成功了几个，但是大部分还是没有安装成功，下面是vscode详细的安装日志：

其实去src目录下看的话，是下载成功了，但是没有安装成功，并且我们也可以看出有几个是可以直接安装成功的
github.com/nsf/gocode
github.com/tpng/gopkgs
github.com/fatih/gomodifytags
github.com/haya14busa/goplay
github.com/rogpeppe/gode
github.com/derekparker/delve/cmd/dlv
解决方法
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%srcgithub.comgolang
我这里的GOPATH是在D:go_project
如果src目录下面没有github.comgolang请自行创建
完成目录切换后，开始下载插件包：
git clone https://github.com/golang/tools.git tools
当下载完成后，你会发现%GOPATH%srcgithub.comgolang多了一个tools目录
需要把tools目录下的所有文件拷贝到%GOPATH%srcgolang.orgx ools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%srcgolang.orgx ools
目录下，你可以直接使用如下命令进行拷贝：
xcopy /s /e %GOPATH%srcgithub.comgolang ools
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%srcgolang.orgx ools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
