【问题描述】：

我正在使用：Ubuntu Ubuntu 15.04 x64, Ruby 2.1.4, Rails 4.2.3, Passenger 5.0.0.rc2 or later tryed, Apache 2.4.10。

我无法在生产中启动项目，因为收到错误消息：

【解决方案1】：

“无法下载”不是这里的实际问题。如您所见，它后来说“继续没有passenger_native_support”，这意味着它退回到不需要下载任何东西的机制。实际问题是在那之后出现的：“无法加载此类文件--bundler/setup”。这可能意味着您的应用程序正在以错误的用户身份运行。检查 /tmp/passenger-error-V7RWyB.html 中的错误详细信息转储，并仔细检查所有设置是否正确。特别是，仔细检查用户是否正确，并阅读Passenger's user account sandboxing 以了解如何解决该问题。
