Oh no, an error occurred.

I guess you’re here is because you’re using M1 for your Xcode project with Cocoapods, but you cannot perform pod install right?

The error message is a little frunstrating but at the same time it is very clear:

LoadError — dlopen(/Library/Ruby/Gems/2.6.0/gems/ffi-1.14.2/lib/ffi_c.bundle, 0x0009): missing compatible arch in /Library/Ruby/Gems/2.6.0/gems/ffi-1.14.2/lib/ffi_c.bundle — /Library/Ruby/Gems/2.6.0/gems/ffi-1.14.2/lib/ffi_c.bundle

This line is very clear that some architecture is missing for building this pod. Apparently M1 mac does not have x86_64 arch.

So the solution is to run below two lines in terminal:

  • sudo arch -x86_64 gem install ffi
  • arch -x86_64 pod install

Now it should be working. ;) Happy coding

Error in terminal
