今天 在安装gdb调试工具时，我的mac死活安装不上证书，google上我也没找到解决方案，我只能换了一个调试工具采用了delve，但是结果也很不爽 安装不上，可能是系统升级到 High Sierra的原因，最终从 github上找到一个老外的解决方案，记录在此。

下面是其回复：
actually I did this:
cd $HOME/Library/Caches/Homebrew
tar xf delve-*.gz
go into directory ( mine is delve-1.0.0-rc.1 )
sh scripts/gencert.sh
it will asks for password, and you're done.
After that just re run brew install go-delve/delve/delve
and it will pass without problems
再次安装
brew install go-delve/delve/delve
检查是否成功
dlv version
Delve Debugger
Version: 1.0.0-rc.2
Build: v1.0.0-rc.2
完美解决，终于将其安装成功。
