How to resolve this.....

Sometimes After installing the DevKit I faced the same issue again..... 
So I tried to solve this.... 


Solution:
Goto your command prompt
Look for which ruby
Goto the installed folder package in ruby....
Remove or Rename the 'GEMS' folder in the ruby package.
In command prompt give GEM LIST command... It will show empty gem list....
So we removed all the installed GEMS... Its time to install the gem files again... Now it will work....
