Rails 3.2.1：％1不是有效的Win32应用程序。-c：/ RailsInstaller

昨晚我正在使用Rails 3.2.1应用程序，并且一切正常。但是，今天早上我跑步时rails server，我遇到了一个奇怪的问题：

> c:/RailsInstaller/Ruby1.9.3/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:

我只是花了很多时间寻找解决方案，我的一些发现是Rails安装程序的问题：

https://github.com/oneclick/rubyinstaller/issues/102
https://github.com/oneclick/rubyinstaller/wiki/Troubleshooting#wiki-dep_segfault

但是故障排除/修复似乎并不适用于我，因为我不记得曾经见过“ FRAPS”或“绕道而行”的情况。

谁能解释一下为什么突然发生这种情况？任何解决方案/尝试将不胜感激！
