无法修改冻结数组 (TypeError) - config/application.rb:42:in `<<':

问题描述

我有一个 rails 3 应用程序，正在尝试进行测试.我执行以下命令 rspec spec/controllers/并收到以下错误:

I have a rails 3 app, and am trying to do testing. I do the following command rspec spec/controllers/ and get the following error:

/config/application.rb:42:in `<<': can't modify frozen array (TypeError)
        from c:/Users/#####/documents/#####/config/application.rb:42

它指向我在下面提供的 config/application.rb 文件.

It is pointing to my config/application.rb file which I have provided below.

require File.expand_path('../boot', __FILE__)

require 'rails/all'

# If you have a Gemfile, require the gems listed there, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(:default, Rails.env) if defined?(Bundler)

module PadOnRails
  class Application < Rails::Application
    # 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.

    # Custom directories with classes and modules you want to be autoloadable.
    # config.autoload_paths += %W(#{config.root}/extras)

    # Only load the plugins named here, in the order given (default is alphabetical).
    # :all can be used as a placeholder for all plugins not explicitly named.
    # config.plugins = [ :exception_notification, :ssl_requirement, :all ]

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

    # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
    # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
    # config.time_zone = 'Central Time (US & Canada)'

    # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
    # config.i18n.default_locale = :de

    # JavaScript files you want as :defaults (application.js is always included).
    # config.action_view.javascript_expansions[:defaults] = %w(jquery rails)

    # Configure the default encoding used in templates for Ruby 1.9.
    config.encoding = "utf-8"

    # Configure sensitive parameters which will be filtered from the log file.
    config.filter_parameters += [:password]

    config.autoload_paths << "#{config.root}/lib"


  end
end

有没有其他人遇到过这种确切的问题.如果是这样，你如何解决它，因为我已经删除了我的项目并且做了一个 git clone 并且仍然得到同样的错误.

has anyone else experienced this exact kind of problem. If so how do you fix it because I have deleted my project and did a git clone all over and still get the same error.

推荐答案

试试评论建议的方法:

config.autoload_paths += %W{#{config.root}/lib}

这不会修改初始数组，而是将给定数组添加到 config.autoload_paths 并将其保存到 config.autoload_paths 中的新数组中.

This doesn't modify the initial array, but adds the given array to config.autoload_paths and saves it into a new array in config.autoload_paths.
