I am getting the above error ..

How to resolve this ??

Answer 1

This is happening because you installed RubyGems that is too new for your version of Rails. Either downgrade (and re-run update_rubygems) or upgrade Rails to 2.3.11.

Answer 2

The solution is fairly simple. Just run the following commands to go back to the previous version of rubygems and you should be fine:

$ gem install rubygems-update -v='1.4.2'
$ gem uninstall rubygems-update -v='1.5.0'
$ update_rubygems

Answer 3

This could be because you have rails 3 installed but are trying to run a rails 2.3.4 app. I've had this problem before and the solution was to remove rails 3 because this dependency is one of rails 3, not 2.3.4

Answer 4

Your gem list (the one you get on the command "gem list") is list of installed gems.

That's not the list of gems used by your application -> those are in the Gemfile.

Things you might try or have tried:

• update_rubygems
• bundle install

(see also https://gist.github.com/807008 )

Answer 5

OK I just upgraded a Rails app from 2.3.4 to 2.3.14 and got the same error.

However I had already downgraded rubygems to 1.3.5 (as recommended in another answer) to get around a similar error after upgrading the core Ruby package

So i took a punt and upgraded to the latest version:

sudo gem update --system

This gave me version 1.8.24

and everything started working again. shrug

Perhaps that throws the issue into a somewhat different light.

Answer 6

I know there's already an answer for this, but when I was running an older rails, I specified script/server webrick after having the same problem and this worked. This may not be ideal for production, however, and I recommend upgrading as mentioned in the other answer.
