【解决方案1】：

您是否检查过bundler 已安装在您的机器上？

我更喜欢 rbenv 而不是 rvm，而不是 100% 熟悉如何使用 RVM 安装 bundler gem，但这个 article 可能会有所帮助。

【讨论】：

感谢您的评论。不幸的是，这篇文章没有解决这个问题。我会继续挖掘...
我最终以我在 capistrano 中使用的“部署”用户身份重新安装了 RVM、Bundle 和 Rails。可能是apache目录中的某种路径问题。感谢您的时间和回答。

【解决方案2】：

我在安装过程中遇到了类似的错误，只是找不到预加载器，这就是问题所在。

我从 apache-passenger 安装程序安装了乘客，并以这种方式从源安装它，所以它是最新的。

当我安装 gem 时，我只是使用 gem install Passenger，它不是最新的。丢失的文件在旧版本中，但不在新版本中，所以我最终不得不这样做 rsync -av --ignore-existing /path/to/passenger-out-of-date-folder/ /path/to/passenger-up-to-date-folder/
