Why does Ruby 1.9.2 blow up with a JSON gem dependency?

Question

I am having issues with the JSON gem and Ruby 1.9.2. I am upgrading to Rails 3.0.3 and whenever I try to boot the environment it blows up. This is from a empty test project with only JSON gem 1.4.6 as a dependency.

I had some weird issues after upgrading to Snow Leopard because of the 64-bit difference so if you upgraded to Snow Leopard you might be running into the same thing.

I installed the latest XCode, then blew away my 1.9.2 install using rvm uninstall 1.9.2 and rebuilt all the gems using gem update --system; gem pristine --all.

You sir are the smartest man alive. Thanks so much! gem pristine --all did the trick! – Lee Nov 24 '10 at 14:26

I'm not smart, I'm just a veteran of that particular battle. I'm glad it helped. – the Tin Man Nov 24 '10 at 16:04

I just had the same problem on Ubuntu - `gem pristine --all` was what I needed. THANK YOU. – Skilldrick Jul 01 '11 at 23:38
@theTinMan I'll join in on the love fest and say that this answered saved my work day ^^ thanks a lot – marcgg Oct 05 '11 at 10:29
Also worked for me on Ubuntu 11.10 x64, rvm 1.10.2, ruby 1.9.3, rails 3.1.3. webrick was crashing after serving the first request. – Brian Jan 20 '12 at 03:28

THANK YOU for the answer! gem pristine --all is my new bicycle. – Eric Mill Apr 17 '12 at 00:09
no luck with this, moreover the redmine is not starting at all after this, so be careful! – Soul_man May 30 '13 at 03:48
This question and answer is to fix problems with Ruby and JSON. It tells Rubygems to reinstall all gems from their locally cached versions, in case something changed. RedMine should continue to work unless it modifies Rubygems or particular gems from their defaults and, if it does, then shame on them. Perhaps it'd be a good idea for you to create a question describing the problem you're seeing and some RedMine folks can chime in. As is, it sounds like you took a wild-chance fixing some undefined/undescribed problem and it failed. – the Tin Man May 30 '13 at 15:48

Why does Ruby 1.9.2 blow up with a JSON gem dependency?
