ROR +遷移命令給出奇怪的錯誤消息

Question

Facing a strange problem while running migration command for creating one column. 

from /usr/lib/ruby/1.9.1/rubygems/specification.rb:777:in `block in activate_dependencies' 
from /usr/lib/ruby/1.9.1/rubygems/specification.rb:766:in `each' 
from /usr/lib/ruby/1.9.1/rubygems/specification.rb:766:in `activate_dependencies' 
from /usr/lib/ruby/1.9.1/rubygems/specification.rb:750:in `activate' 
from /usr/lib/ruby/1.9.1/rubygems/specification.rb:780:in `block in activate_dependencies' 
from /usr/lib/ruby/1.9.1/rubygems/specification.rb:766:in `each' 
from /usr/lib/ruby/1.9.1/rubygems/specification.rb:766:in `activate_dependencies' 
from /usr/lib/ruby/1.9.1/rubygems/specification.rb:750:in `activate' 
from /usr/lib/ruby/1.9.1/rubygems.rb:212:in `rescue in try_activate' 
from /usr/lib/ruby/1.9.1/rubygems.rb:209:in `try_activate' 

無法配置爲什麼這樣的錯誤是在控制檯到來。

經過Google長時間的努力，我得到了解決方案來解決我的問題。

由於寶石衝突增加束exec來我轉移命令

bundle exec rails generate migration AddStatusToUser status:boolean 

當我發現了一些問題的發生。
