我的Ruby版本是：

c:\Sites\new\app1>ruby -v
ruby 2.0.0p353 (2013-11-22) [i386-mingw32]

c:\Sites\new\app1>rails -v
Rails 4.0.2

Rails版本为：

c:\Sites\new\app1>ruby -v
ruby 2.0.0p353 (2013-11-22) [i386-mingw32]

c:\Sites\new\app1>rails -v
Rails 4.0.2

我还发现了这两个关于GitHub上类似错误的对话

但我找不到解决问题的办法

有人能帮我吗？ 非常感谢。 斯特凡诺
