How do you downgrade rubygems?

Question

I have rubygems 1.3.1 installed but I want to go back to 1.2.0. What\'s the command to downgrade rubygems?

Answer 1

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.
