解决方案

确保你已经安装了 Apple Xcode 和命令行工具(看这个截图):

之后，别忘了安装 libffi.

1) 如果您使用的是自制软件

brew install libffi

2) 如果您使用的是 macport

sudo 端口安装 libffi

解决方案

Make sure that you have installed Apple Xcode and Command Line Tools (look at this screenshot):

After that, don't forget to install libffi.

1) if you are using homebrew

brew install libffi

2) if you are using macport

sudo port install libffi
