Question

我最近将我的应用程序从Rails版本2.1.2升级到版本2.2.2。它在开发和我的临时系统上进行了测试。当我转移到生产时，它无法一直加载到environment.rb文件中。（为什么，为什么，它一直在生产！？！）

下面是我的environment.rb文件

# Be sure to restart your web server when you modify this file.

# Uncomment below to force Rails into production mode when 
# you don't control web/app server and can't set it the proper way
# ENV['RAILS_ENV'] ||= 'production'

  # Settings in config/environments/* take precedence over those specified here

  # Skip frameworks you're not going to use (only works if using vendor/rails)

  # config.plugins = %W( exception_notification ssl_requirement )

  # Add additional load paths for your own custom dirs
  # config.load_paths += %W( #{RAILS_ROOT}/extras )

  # Force all environments to use the same logger level 
  # (by default production uses :info, the others :debug)
  # config.log_level = :debug

  # Use the database for sessions instead of the file system

  # Activate observers that should always be running
  # config.active_record.observers = :cacher, :garbage_collector

  # Make Active Record use UTC-base instead of local time

如果我将rails gem用于版本2.1.2，那么所有内容都会加载，所有puts语句都会按预期打印。当我将gem版本更改为2.2.2时，我看到的最后一个语句是“setting smtp settings”。

当我将Rails::Initializer do |config|部分移到底部时，它的失败方式比现在更糟糕。

系统上加载的ruby版本是Ruby 1.8.6 patchlevel 111.它在RHEL5-64bit上运行。

我很难过。想法？建议？

Answer 1

你有没有运行rake rails：update？

另外，您可能希望将大部分代码移动到config / initializers / [anything] .rb，尽管我很难想到它本身会解决您的问题。

Rails没有正确加载environment.rb
