Answer 1

我对Dreamhost / Passenger / Rails也有同样的问题。我发送支持请求并收到以下回复。我的网站现在也正常运行。

感谢您联系技术支持。我为这个问题道歉。服务器最近升级到了Debian，并对你的安装进行了一些升级。我继续前进并纠正了有错误的网站，因为需要重新安装一些宝石。

我为这个问题道歉。如果还有什么我可以为你做的，请告诉我，祝你有个美好的一天。

Answer 2

我遇到了同样的问题，它与正确捆绑我的宝石有关。服务器正在/usr/lib/ruby/gems/1.8/寻找所需的宝石。在服务器上重新运行bundle install纠正了我的问题。希望这会帮助其他人，因为这个问题似乎有很多原因。
