乘客错误：应用程序生成器服务器意外退出：检测到意外的文件结束
这只是前一天工作，但我刚刚将我的代码更新到运行Passenger 2.2.4的评论服务器，而我的2.3.4 rails应用程序现在无法在该框上启动。
乘客报告：
Passenger encountered the following error: The application spawner server exited unexpectedly: Unexpected end-of-file detected. Exception class: PhusionPassenger::Railz::ApplicationSpawner::Error Backtrace: # File Line Location 0 /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4/lib/phusion_passenger/railz/application_spawner.rb 218 in `start' 1 /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4/lib/phusion_passenger/spawn_manager.rb 261 in `spawn_rails_application' 2 /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4/lib/phusion_passenger/abstract_server_collection.rb 126 in `lookup_or_add' 3 /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4/lib/phusion_passenger/spawn_manager.rb 255 in `spawn_rails_application' 4 /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4/lib/phusion_passenger/abstract_server_collection.rb 80 in `synchronize' 5 /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4/lib/phusion_passenger/abstract_server_collection.rb 79 in `synchronize' 6 /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4/lib/phusion_passenger/spawn_manager.rb 254 in `spawn_rails_application' 7 /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4/lib/phusion_passenger/spawn_manager.rb 153 in `spawn_application' 8 /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4/lib/phusion_passenger/spawn_manager.rb 286 in `handle_spawn_application' 9 /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4/lib/phusion_passenger/abstract_server.rb 351 in `__send__' 10 /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4/lib/phusion_passenger/abstract_server.rb 351 in `main_loop' 11 /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4/lib/phusion_passenger/abstract_server.rb 195 in `start_synchronously' 12 /usr/lib/ruby/gems/1.8/gems/passenger-2.2.4/bin/passenger-spawn-server 61 有任何想法吗？
弄清楚了。 我终于检查了主apache错误日志，发现我的一个gem（facebooker config）出现了问题。
要解决facebooker问题，请确保在config / facebooker.yml中为您的环境提供了一个条目
我认为乘客至少可以选择查看更多在apache的错误日志中报告的堆栈跟踪。 本来会更有帮助。
当我忘记初始化数据库时，我遇到了同样模糊的错误。 如果是这样，请尝试：
RAILS_ENV=production bundle exec rake db:setup
