vscode安装go的很多插件都是失败，如下：

最后在网上找到了解决办法。概要如下：
1.Tips：安装之前先检查下 %GoPath%\src\golang.org\x 下的tools/lint是否是从github获取的最新版本(注意一定要是git clone)，正确如下图所示
因为后面安装 组件会大量用到这个tools和lint，如果不是最新或不是git clone更新组件会出现大量的：
directory "D:\GoPath\src\golang.org\x\tools\go\buildutil" is not using a known version control system
解决办法：
由于很多源代码引用了golang.org官方原生的一些代码，因此如果不存在的话会导致第三方的源代码会编译不通过，第一次使用文件夹不存在创建一个。这与golang本身的包管理机制不健全有很大的关系。
另一篇文章 window下golang包管理glide使用说明也是解决类似问题。go官方也许会在go2.0的版本解决此问题
1)在%GoPath%\src\golang.org\x 目录下git clone [email protected]:golang/tools.git，注意，只能git clone
2)在%GoPath%\src\golang.org\x 目录下git clone [email protected]:golang/lint.git，注意，只能git clone
2.官方文档说明 https://github.com/Microsoft/vscode-go/wiki/Go-tools-that-the-Go-extension-depends-on
也可以通过ctrl+shift+p 运行该命令一次性安装所有这些工具

组件安装过程稍微有一点慢，耐心的等待...

经过步骤三的tools和lint的clone后安装正常都应该是SUCCEEDED ，且不需要墙，如遇个别安装FAILED 再单独执行go get ...，看还缺少什么在github.com/golang 中找到相应的组件按同样的方法clone在golang.org/x文件夹下
TIPS：go版本和组件全部都重新安装一遍后也能解决vscode 运行go卡的问题，具体原因不详，建议go版本更新后最好都重新安装下组件。
之前一直嫌弃vscode运行go卡而用liteide。重新开始用vscode主要原因： 1、颜值高 2、vscode已成为了非常流行的IDE
3.cannot find package错误
检查go环境配置，新安装的go1.10.2的版本默认会在当前用户新增一个GOPATH导致冲突无法编译，删除即可
4.调试
1）vscode打开main.go直接F5就可以运行&调试
2）生成exe，vscode F5运行会在根路径下生成一个debug文件，把debug文件重命名加.exe后缀可以直接当应用程序运行
另一种方式cmd切换到项目文件夹下用
go build -o demo.exe main.go
意思是main.go生成名为demo.exe应用程序,go build生成的exe实际比debug要小。
