Answer 1

I fixed it by running

brew install cocoapods

And You may want to remove it:

rm '/usr/local/bin/pod'

To force the link and overwrite all conflicting files:

brew link --overwrite cocoapods

Install homebrew if you haven't already. https://brew.sh/

Answer 2

Try adding --disable-system-libffi to the gem install command.

This worked for me:

gem inst cocoapods -- --disable-system-libffi
