Make sure that you have installed Apple Xcode and Command Line Tools (look at this screenshot):
确保你已经安装了 Apple Xcode 和命令行工具（看这个截图）：

https://developer.apple.com/technologies/tools/
After that, don't forget to install libffi.
之后，不要忘记安装libffi。
1) if you are using homebrew
1）如果您使用的是自制软件
brew install libffi
2) if you are using macport
2) 如果您使用的是 macport
sudo port install libffi
