Can't get a gem

I tried to install a gem but terminal says "You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory." What should I do?

Try using sudo on that gem, like this:

sudo gem install #Whatever gem you're trying to install

It'll ask you for your password, which should be the same as the one you use to log into your Mac. It won't look like it's accepting your input while you're typing your password, but I promise it is
