I have tried everything to install cocopods on a M1 mac.

When I do a brew install cocoapods it apparently goes without a problem but when I try to issue pod install I see

pod install zsh: command not found: pod

They I tried to install sudo gem instal ffi

I see this error

I have tried this with the terminal running using and not using rosetta. No difference.

I also see a lot of errors like

: warning: It seems your ruby installation is missing psych (for YAML output).

Even after reinstalling yaml

I have tried numerous guides to install cocoapods. None work.

How do I solve this?

  • That is an old version of ruby in is not even the latest in the 2.x line and that has been end of lifed. try a newer one. Although Homebrew should really deal with this.

Try this command: sudo gem install -n /usr/local/bin cocoapods -v 1.8.4

    Are you asking the OP to try this or are you offering it as a solution? If it is a solution, it would be helpful to state why it helps (even though it seems obvious) and to provide some instructions/documentation to verify your solution.
