Segmentation fault when running 'rails s'

Question

After doing a bundle install, I run 'rails s' it runs into this error.

$ rails s

/Users/XXXX/.rvm/gems/ruby-1.8.7-p352@r3/gems/json-1.5.3/ext/json/ext/json/ext/parser.bundle: [BUG] Segmentation fault
ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-darwin10.8.0]

Abort trap

Any help would be greatly appreciated. Thanks!

Answer 1

1. rvm gemset empty
2. rvm use ree@my-gemset
3. gem install bundler
4. bundle install

This solved the issue for me. Must be some extension got compiled against the wrong version of Ruby (in my case). Hope it works for you!

If you are not using RVM, I found this command to uninstall all gems:

1. 'gem list | cut -d" " -f1 | xargs gem uninstall -aIx'
2. gem install bundler
3. bundle install

Answer 2

Your gemset is not compiled for the version of ruby you are using. I found this worked for me:

1. rvm gemset empty
2. rvm gemset create your_gem_set_name
3. rvm use 1.8.7@your_gem_set_name --default
4. bundle install
