任何想法，爲什麼發生這種情況？我使用Ubuntu的，有紅寶石1.9.3-P194和導軌安裝2.3.14我的系統上，並使用sqlite3的

檢查你所安裝的版本的Rails：

$ gem list rails 

*** LOCAL GEMS *** 

rails (3.2.3, 2.3.14)

你應該讓他們多像我在這裏做的3.2.3和2.3.14

之後卸載那些你不需要：

$ gem uninstall rails -v2.3.14 
Remove executables: 
    rails 

in addition to the gem? [Yn] Y 
Removing rails 
Successfully uninstalled rails-2.3.14

at th Ë結束時，你應該只有一個版本的軌道：

$ gem list rails 

*** LOCAL GEMS *** 

rails (3.2.3)

奇怪，我得到一個空的列表，但我絕對有軌龍頭安裝 hilarl @ isa009：〜/工作區/車廠$寶石列表軌 ***當地的寶石*** hilarl @ isa009：〜/工作區/車廠$ – hilarl

確定它的工作，不得不重新安裝出於某種原因軌寶石。非常感謝 – hilarl

你可以嘗試運行

bundle exec rake db:migrate

你可以有不同版本的同一寶石安裝在您的系統中 - 因此bundle exec <command>使用其版本與您的項目綁定的gem Gemfile（在Gemfile.lock文件中搜索您的gem以查看正在使用的版本）。

更好的做法是創建gemset來打包選擇的gem版本，這些gemset將根據上下文中的項目激活。

當我嘗試，我得到「無法定位的Gemfile」 – hilarl
