solution
Look at the error message, because Cocoapod depends on ffithe package, and ffithe structure of the package is not compatible.
Because starting from m1, macbook uses an ARM architecture CPU, which is incompatible with the previous x86 architecture software. We only need to convert ffi into a package compatible with x86 architecture.
Run the following 2 commands
sudo arch -x86_64 gem install ffi
arch -x86_64 pod install
