安装Visual Studio Code在此不详细说明了，网上资料一堆，在此简单说明下安装过程的坑：

先后安装好Visual Studio Code、golang扩展插件、以及扩展插件所依赖的包后，调试发现报错，主要原因是 dlv这个依赖包安装出了问题，我们一般是用go get 来安装的：

go get -u -v github.com/derekparker/delve/cmd/dlv

这在windows系统下是没问题的，但在mac下不行，网上说是因为签名权限等，因此最好用brew命令来安装，例如：

brew install go-delve/delve/delve

但安装失败：

If reporting this issue please do so at (not Homebrew/brew or Homebrew/core):

去github官方仓库去查，有人遇到类似的问题，如下解决：

https://github.com/go-delve/homebrew-delve/issues/17

I fixed this by manually installing the cert (unzip the cached .tar.gz, run gencert which lives in scripts):

$ cd ~/Library/Caches/Homebrew/delve-1.0.0-rc.1/scripts
$ ./gencert.sh
