I get the error above.

How to resolve this?

Answer 1

This is because you installed RubyGems, which is too large for your version of Rails. Either downgrade (and run update_rubygems again), or upgrade Rails to version 2.3.11.

Answer 2

The solution is pretty simple. Just run the following commands to revert 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 may be due to the fact that you installed rails 3, but trying to run the rails 2.3.4 application. I 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

The gem list (the one you get in the gem list command) is a list of gems installed.

This is not a list of gems used by your application -> those found in the Gemfile.

What you can try or have tried:

• update_rubygems
• install package

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

Answer 5

I know there is already an answer for this, but when I was working with older rails, I set up the script / server webrick after you had the same problem and it worked. However, this may not be ideal for production, and I recommend updating as indicated in another answer.

Answer 6

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

However, I have already lowered the rating of rubigems to 1.3.5 (as recommended in another answer) in order to circumvent a similar error after updating the main Ruby package

So, I took a punt and updated it to the latest version:

 sudo gem update --system 

This gave me version 1.8.24

and it all worked again. shrug

Perhaps this poses a problem in a slightly different light.
