Description
I want to install cocoapods on MacOS to run the pod command. But on doing
sudo gem install cocoa-pods
I get the following:
Building native extensions. This could take a while...
ERROR: Error installing cocoapods:

and running
brew install libffi
gives:
% brew install libffi
Warning: libffi 3.3 is already installed and up-to-date
To reinstall 3.3, run `brew reinstall libffi`
How to fix this?
And when I install cocoapods using brew, I get:
Warning: cocoapods 1.9.3 is already installed and up-to-date
To reinstall 1.9.3, run `brew reinstall cocoa-pods
Yet when I do:
pod --version
I get:
pod --version
