I have been having trouble install Rails from the terminal on my new
MacBook. I have tried to find a solution on both google and youtube, but
I have not find a solution to the problem

$ rails -v
Rails is not currently installed on this system. To get the latest
version, simply type:

   $ sudo gem install rails

You can then rerun your "rails" command.

$ sudo gem install rails
Building native extensions.  This could take a while...
ERROR:  Error installing rails:
