日志显示这是一个名称错误。我建议您指定正确的范围。Rails有一种非常复杂的查找常量的方法。我建议你看看这个：

还有这个

。

希望有帮助。

看起来您使用的Mongo是1.3.1，BSON可能是2.0。这些似乎不在一起工作。我会试着把1.9 BSON放在那里，看看是否有效

您可以通过添加以下内容来执行此操作： gembson，~>1.9.2

到你的档案

希望有帮助？

您使用ruby 2.0.0而不是1.9.x有什么原因吗？你试过1.9.x吗？您是否可以在本地检查是否可以找到BSON:：ByteBuffer，即ruby-e'require BSON；放BSON:：ByteBuffer'？并在heroku控制台的irb中执行类似操作，如本文所述？此外，在app.rb的第21行中，条件为除非db.user.nil？| |db.user.nil？。我想你是想测试db.password.nil？而不是db.user.nil？两次，我试过了。如果我运行ruby-e'requirebson；将BSON:：ByteBuffer'放在本地计算机上，我得到未初始化的常量BSON:：ByteBuffer。现在使用ruby 1.9.2，我得到了相同的错误。在本地和部署的版本上。我的rails应用程序一直运行良好，直到今天。@asprott你解决了吗？阅读它。我想不出这个案子有什么问题
