您是否检查过您的计算机上安装了bundler？

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

Answer 2

我的安装中遇到了类似的错误，除了找不到预加载器，这就是问题所在。

我从apache-passenger安装程序安装了乘客并从源头安装了这个，所以它是最新的。

当我安装宝石时，我刚刚使用了宝石安装乘客，这是不是最新的。丢失的文件是在旧版本中，但不是在较新版本中，所以我最终不得不这样做 rsync -av --ignore-existing /path/to/passenger-out-of-date-folder/ /path/to/passenger-up-to-date-folder/
