sudo gem install -n /usr/local/bin cocoapods -v 1.8.4

It worked for me.

is just easier install cocoapods separately (eg: using brew), and exporting the path.

Try "brew install cocoapods" instead and it will get cocoapods installed without this error.

It's customary to advise people to install something like rvm or rbenv before installing CocoaPods. As one of the developers behind CocoaPods I'd like to say that you don't have to do any of that unless you are planning to do ruby work yourself. If you're just interested in getting CocoaPods to work there's no need for all the overhead of a ruby manager.

To quote the CocoaPods guides:

CocoaPods is built with Ruby and it will be installable with the default Ruby available on OS X. You can use a Ruby Version manager, however we recommend that you use the standard Ruby available on OS X unless you know what you're doing.

Using the default Ruby install will require you to use sudo when installing gems. (This is only an issue for the duration of the gem installation, though.)

$ sudo gem install cocoapods

You're on Mac OS. To get:

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/include/ruby.h

you're trying to install gems into your system Ruby, which was installed by Apple for their use.

Don't do that.

Instead, use either rbenv or RVM to manage/install Rubies in a separate sandbox, where you're free to fold/spindle/mutilate to your heart's content.

If you opt for RVM, *read the ENTIRE installation instructions* before starting. RVM is very full-featured, and flexible, and those come at a price of additional "options" (AKA "complexity") when installing. Do it as a single-user, do not EVER use sudo, and you should be fine.

We can piggyback on Apple's system-instalation of Ruby, but don't modify it unless you really understand what you're doing; The error above makes me think this isn't the case.

To install a Ruby other than Apple's pre-installed one, odds are really good you'll need the current Xcode, along with the command-line extensions. That will provide the tools necessary to compile native extensions, plus all the headers needed:
