前言

今天拉代码下来pod install报错如下：

/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/universal-darwin20/rbconfig.rb:229: warning: Insecure world writable dir /opt/homebrew in PATH, mode 040777

-- Ruby level backtrace information ----------------------------------------
/usr/local/bin/pod:23:in `<main>'
/usr/local/bin/pod:23:in `load'

一直以为是我的pod问题，搞了半天终于找到解决方法：

sudo arch -x86_64 gem install ffi

问题出处：library.rb:275: [BUG] Bus Error at
