我从3.2.1更新到rails 3.2.17。当我运行bundle update和bundle install时，一切都通过了，没有任何错误或警告。然后我重新启动我的服务器，当我加载我的网站时，我得到乘客:WEB应用程序无法启动页面。下面是该页上列出的所有内容的副本。有什么想法，我可能需要改变或检查，使事情运行?
It looks like Bundler could not find a gem. Maybe you didn't install all the gems that this application needs. To install your gems, please run:
bundle install
If that didn't work, then the problem is probably caused by your application being run under a different environment than it's supposed to. Please check the following:
Is this app supposed to be run as the root user?
Is this app being run on the correct Ruby interpreter? Below you will see which Ruby interpreter Phusion Passenger attempted to use.
-------- The exception is as follows: -------
Could not find rake-10.2.1 in any of the sources (Bundler::GemNotFound)

您的应用程序以root身份运行，使用system ruby，并且您可能以不同的用户安装了gems，使用不同的ruby安装，例如在rvm或rbenv下。
最简单的解决方案是以root身份运行bundle install。好运！
