When I try to install Cocoapods after having uninstalled it, using the following line of code:
sudo gem install cocoapods
I get the following error:
ERROR: Error installing cocoapods:

For context; I did uninstall ffi and cocoapods, as someone on GitHub said that was the solution to another problem I was having. Then when I was supposed to install Cocoapods again, I got where I am right now.
I don't understand why this happens. Any ideas?
