解决vscode中golang插件依赖安装失败问题

vscode中安装ms-vscode.go插件后可以开启对go语言的支持,ms-vscode.go插件需要依赖一些工具,安装完成后提示

8 tools failed to install.

由于网络原因，一些依赖工具无法正常安装，需要进行手动安装.

以下为手动安装的工具的步骤:

1. 在%GOPATH%\src\目录下，建立路径golang.org\x

2. 进入到%GOPATH%\src\golang.org\x，下载需要工具的源码git clone https://github.com/golang/tools.git tools

3. clone完成后，会生成一个tools文件夹，这样工具所需要的源码已经准备好了

4. 进入到%GOPATH%下，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/rogpeppe/godef
   
       go install github.com/sqs/goreturns
   
       go install github.com/cweill/gotests/gotests
   
   
   

5. 单独处理golint,golint的源码位于https://github.com/golang/lint,进入%GOPATH%\src\golang.org\x后执行git clone https://github.com/golang/lint下载golint需要的源码

6. 进入到%GOPATH%下，执行go install github.com/golang/lint/golint

这样，vscode的golang插件所依赖的工具安装完成了。
