When you see Gem error like - "'': uninitialized constant Gem::SilentUI (NameError)"


I just created a new Rails 3 project called dashboard and tried having bundler install all the required basic gems for this project using the command - bundle install. Damn!, I got the error that is the title for this blog post.
Below is the snap shot of the command and the error:

karthik@cloud:~/MyRubyProjects/beach_projects/dashboard$ bundle install
/home/karthik/.rvm/gems/ruby-1.9.2-p0@rails3/gems/bundler-1.0.7/lib/bundler/ui.rb:56:in '<class:UI>': uninitialized constant Gem::SilentUI (NameError)

from /home/karthik/.rvm/gems/ruby-1.9.2-p0@rails3/bin/bundle:19:in `<main>'

What is the issue? The issue is perhaps with the version of bundler and its dependencies. To resolve this issue, I ran the gem update for the bundler and know what? It worked ;)
Below is the snap shot of the command and the output:

karthik@cloud:~/MyRubyProjects/beach_projects/dashboard$ gem update bundler
Updating installed gems
Updating bundler
Fetching: bundler-1.0.15.gem (100%)
Successfully installed bundler-1.0.15

After this I tried running the "bundle install" command and the required gems were installed successfully.
Below is the snap shot of the command and the output:
