從表格版本4切換到版本3後，rails server無法啓動

Question

我使用的是rails 3.2.6版本，最近我從4.0版本降級，因爲我想在3版本的環境下工作，因爲教程im跟着他們使用的是版本3。 我在Windows 7機器上，這是我迄今爲止所做的。 我第一次做了寶石安裝rails -v 3.2.6
然後我做了寶石卸載rails，並選擇我想安裝的版本。
然後，我降級了依賴於rails版本4的gem，並且在運行軟件包安裝時沒有收到任何錯誤。
現在，當我嘗試做軌道s到看到永遠不會發生什麼打破了我的頁面上的服務器，我也得到了一堆文件名：

=> Rails 3.2.6 application starting in development on http://0.0.0.0:3000 
=> Call with -d to detach 
=> Ctrl-C to shutdown server

我知道這可能是一堆垃圾了一些，但如果有人能幫助我，這將是非常棒的。如果您需要更多信息，請告訴我。 預先感謝您。

由於我在windows上使用rails，RVM無法正常工作，所以我使用了pik gem，並將該環境更改爲3.2.6，然後工作正常。
