macOS pod install失败

macOS 系统上运行pod install命令行报错：

-- Crash Report log information --------------------------------------------

   See Crash Report log file under the one of following:                    

     * ~/Library/Logs/DiagnosticReports                                     

     * /Library/Logs/DiagnosticReports                                      

   for more details.                                                        

Don't forget to include the above Crash Report log file in bug reports.     

经过搜索多种方案，最终找到以下解决办法：

命令行中执行以下命令行即可

sudo arch -x86_64 gem install ffi
arch -x86_64 pod install
原因可能是Ruby的FFI库是一个gem，用于以编程方式加载动态链接的本地库，在其中绑定函数，并从 Ruby 代码调用这些函数。（原文：Ruby-FFI is a gem for programmatically loading dynamically-linked native libraries, binding functions within them, and calling those functions from Ruby code.）
