I am beginner and I can't understand how to fix my error when I try to install Bundle. I'm following the Schneems lessons(currently doing routes_controller_exercise).
Here's my error :
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

I have no idea what to do. I'm a beginner so...be nice with me please ! I've been trying many solutions online, but nothing worked so far! I'm using El Capitan 10.11.1.
I've set up Ruby with this link : http://guides.railsgirls.com/install/#virtual-machine.
Doing this exercise now : https://github.com/schneems/routes_controller_exercise
So I did :
bundle update json
and it worked until :

Building native extensions. This could take a while...

Ok so I've uninstall rails and re-install it with the Stanford website.
And now everything's work perfectly! I have no idea what was the problem, but now I install Bundle with no issues.
One part of the problem is due to a change in rb_str_new.
This is a related issue on their GitHub page: https://github.com/flori/json/issues/229
As I understand it, the contributors decided to not fix this since it works as it should in json 1.8.3. It's recommended that you upgrade to that version. The json gem has a very stable API so backwards compatibility is usually not an issue.
If you are using bundler you should go to your Gemfile and change version of json to 1.8.3 or higher using gem 'json', '>=1.8.3'.
