使用http://www.modrails.com/install.html上的指南，我安装了 Ruby on rails 和 phusion-passenger 以使用 apache2 进行部署。（在 ubuntu-server 上）（这不是开发服务器）。当我运行“rails -s”时，rails 脚本工作正常，但是当我尝试使用 apache 访问服务器时，我得到一个“500 - 内部服务器错误”。
来自apache的错误文件：

任何熟悉此错误的人 - 并想帮助我？
据我了解，这个errorlinge是解决问题的关键，但是谷歌搜索并没有对我有太大帮助。
<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- phusion_passenger/utils (LoadError)
编辑：我发现我的第一个错误是我在 apache 的 mods-enables 文件中写了“bun”而不是“bin”。因此没有将其指向正确的 ruby 目录。
我现在收到乘客产生的错误。说以下：
Ruby (Rack) application could not be started
Error message:
no such file to load -- bundler
然后它继续进行很长的回溯，我将在这里发布一个简短的片段：
