为什么80%的码农都做不了架构师？>>> 
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
run this before brew install go-delve/delve/delve work for me'
