我终于使用 Phusion Passenger 在我的服务器上设置了 RoR，并且显示了默认的 RoR 应用程序页面，但是当我单击“关于您的应用程序的环境”时，我收到一条错误消息，提示“无法启动 Ruby (Rack) 应用程序”在错误消息位下“无法在任何来源中找到 sqlite3-ruby-1.2.5 (Bundler::GemNotFound)”。
如果我在命令行执行“捆绑安装”，我会得到一个“使用 x (y)”样式消息的列表，其中包括:
使用 sqlite3-ruby (1.2.5)
(由于最新版本的问题，我不得不降级到 1.2.5)
我真的不明白为什么我会收到上面的错误，因为 sqlite3-ruby 显然在那里。

最佳答案
您似乎安装了两个版本(ruby-enterprise-1.8.7 和 1.9.1)的 ruby 运行时。确保在同一运行时安装 sqlite3-ruby gem(和 passenger)。
您已经在 1.9.1 ruby 运行时中安装了 passenger gem，但是您将 PassengerRuby 设置为 1.8。我认为你不应该那样做。将其设置为 1.9.1。并确保您使用 ruby 1.9.1 运行 bundle install(在您的 rails 项目文件夹中)，以便将所有需要的 gem 安装到 1.9.1 运行时。
PassengerRuby /path/to/1.9.1/here/bin/ruby
如果您想轻松管理不同版本的 ruby 运行时，我建议您查看 RVM
