M1 pod install出错

LoadError - dlopen(/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.3/lib/ffi_c.bundle, 0x0009): could not use '/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.3/lib/ffi_c.bundle' because it is not a compatible arch - /Library/Ruby/Gems/2.6.0/gems/ffi-1.15.3/lib/ffi_c.bundle.......

安装ffi

sudo arch -x86_64 gem install ffi

如果pod install  出错就得换一下命令

arch -x86_64 pod install
