Answer 1

This fixed the issue for me.

xcode-select -s /Library/Developer/CommandLineTools/

Answer 2

It looks like maybe your Mac doesn't have xcode command line tools installed. Try this in the terminal then try bundling again:

xcode-select --install

You will also need to accept the license agreement. I think it asks you automatically now.

Answer 3

Occur same issue after run sudo gem install cocoapods on my new m1 macbook pro.

↓This fix issue for me too.

xcode-select --switch /Library/Developer/CommandLineTools/

if you doesn't have CommandLineTools folder, just run xcode-select --install
