这项工作是为毕业设计的。我在安装Google智能助理SDK方面遇到了麻烦，但我现在修复了这个问题。但我被卡住了。我需要安装
sudo apt-get install portaudio19-dev libffi-dev libssl-dev
但我认为我需要
brew install portaudio19-dev libffi-dev libssl-dev
然后我收到了这个：
brew install portaudio19-dev libffi-dev libssl-dev
Error: No available formula with the name "portaudio19-dev"
