Today, I got another challenge from @thebosscat to help out the Ruby on Rails case.
Symptoms: the server using RubyGems 1.2.0 and all of the ruby gems could not able updated through “gem update” or even “gem update –system”.
To overcome the problem, I was trying to update the rubygems as step below.
1. Download rubygems version from URL below.
2. Extract the file (in this case, I used the version 1.3.1).
tar -xvf rubygems-1.3.1.tgz
3. Then enter to the path,
4. Run the setup.
5. Verify from the shell again.
