Rails 5 Beta:将eager_load_paths配置放在初始化器抛出冻结数组异常上

Question

我在config/application.rb中遵循了注释指南

   # Settings in config/environments/* take precedence over those specified here.
   # Application configuration should go into files in config/initializers
   # -- all .rb files in that directory are automatically loaded.

但是当我加入Rails.application.config.eager_load_paths << Rails.root.join('lib')时config/initializers/eager_load.rb.

它抛出 <top (required)>': can't modify frozen Array (RuntimeError)

是的,如果我把它放在里面它是有效的config/application.rb.

我想知道为什么它不能用于初始化器以及如何使用约定使其工作？

试试这个config/initializers/xxx.rb：

Rails.application.config.eager_load_paths += [Rails.root.join('lib')]
