I am trying to install cocoapods to my MacBook and after I ran this code into the terminal gem install cocoapods I get the following error:

    Building native extensions. This could take a while...
    ERROR:  Error installing cocoapods:

You might have to install separate package for the ruby development
environment, ruby-dev or ruby-devel for example.

extconf failed, exit code 1

Gem files will remain installed in /Library/Ruby/Gems/2.6.0/gems/ffi-1.12.2 for inspection.

Best Answer

Looks like you don't have installed Ruby development headers.

You can fix this by installing Xcode command-line tools by executing these two commands:

xcode-select --install
sudo xcodebuild -license

Changes will apply after the computer restart.
