vscode安裝go的很多插件都是失敗，如下：

最后在網上找到了解決辦法。概要如下：
1.Tips：安裝之前先檢查下 %GoPath%\src\golang.org\x 下的tools/lint是否是從github獲取的最新版本(注意一定要是git clone)，正確如下圖所示
因為后面安裝 組件會大量用到這個tools和lint，如果不是最新或不是git clone更新組件會出現大量的：
directory "D:\GoPath\src\golang.org\x\tools\go\buildutil" is not using a known version control system
解決辦法：
由於很多源代碼引用了golang.org官方原生的一些代碼，因此如果不存在的話會導致第三方的源代碼會編譯不通過，第一次使用文件夾不存在創建一個。這與golang本身的包管理機制不健全有很大的關系。
另一篇文章 window下golang包管理glide使用說明也是解決類似問題。go官方也許會在go2.0的版本解決此問題
1)在%GoPath%\src\golang.org\x 目錄下git clone git@github.com:golang/tools.git，注意，只能git clone
2)在%GoPath%\src\golang.org\x 目錄下git clone git@github.com:golang/lint.git，注意，只能git clone
2.官方文檔說明 https://github.com/Microsoft/vscode-go/wiki/Go-tools-that-the-Go-extension-depends-on
也可以通過ctrl+shift+p 運行該命令一次性安裝所有這些工具

經過步驟三的tools和lint的clone后安裝正常都應該是SUCCEEDED ，且不需要牆，如遇個別安裝FAILED 再單獨執行go get ...，看還缺少什么在github.com/golang 中找到相應的組件按同樣的方法clone在golang.org/x文件夾下
TIPS：go版本和組件全部都重新安裝一遍后也能解決vscode 運行go卡的問題，具體原因不詳，建議go版本更新后最好都重新安裝下組件。
之前一直嫌棄vscode運行go卡而用liteide。重新開始用vscode主要原因： 1、顏值高 2、vscode已成為了非常流行的IDE
3.cannot find package錯誤
檢查go環境配置，新安裝的go1.10.2的版本默認會在當前用戶新增一個GOPATH導致沖突無法編譯，刪除即可
4.調試
1）vscode打開main.go直接F5就可以運行&調試
2）生成exe，vscode F5運行會在根路徑下生成一個debug文件，把debug文件重命名加.exe后綴可以直接當應用程序運行
另一種方式cmd切換到項目文件夾下用
go build -o demo.exe main.go
意思是main.go生成名為demo.exe應用程序,go build生成的exe實際比debug要小。
