This worked for me when downgrading from 1.5.2 to 1.4.2 because of old rails version:

sudo gem update --system 1.4.2

I had a similar problem in an old Rails 3 stack. When these type of issues occur, my recommendation is to go onto the production server that the application is currently running in and check out which rubygems version it is using:

gem -v

For me, it was using 1.8.24. So all I needed to do is downgrade my current rubygems which was generated from "rvm install 1.9.3", when I installed the old ruby for this app. I ran the following command:

 $ rvm install rubygems 1.8.24 --force

And it worked. Note I am running Ubuntu 14.04 and the server I am using is also Ubuntu.

I used this command to go back to the gem version that my ruby version needed:

rvm rubygems current

If it gives checksum errors try

rvm rubygems current --verify-downloads 1

That did the trick for me.

Updated November 2011: Now that RVM's out, try running rvm install rubygems <version>.

If you're using RVM, then you can do this to remove current ruby gems, then upgrade/downgrade rubygems:

rvm install rubygems 1.4.2

This just worked for me on OSX to get from 1.5.0 back to 1.4.2

sudo gem uninstall -v '1.5.0' rubygems-update
sudo gem update --system --local
