'method_missing': (NoMethodError) 的未定义方法“active_storage”

Question

我目前在 Rails 5.2 应用程序上生成了一个 Ruby。当我运行 rails active_storage:install 它创建了一个 20180915211415_create_active_storage_tables 迁移。但是，当我尝试启动服务器时运行出现以下错误。

/Users/stevenaguilar/.rvm/gems/ruby-2.2.2/gems/railties-5.2.1/lib/rails/railtie/configuration.rb:97:in `method_missing': undefined method `active_storage' for
#<Rails::Application::Configuration:0x007f80bbbf1c18> (NoMethodError)

这是我的 gemfile：

source 'https://rubygems.org'

git_source(:github) do |repo_name|   repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")   "https://github.com/#{repo_name}.git" end

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

在 application.rb 文件中：

require_relative 'boot'

require "rails"
# Pick the frameworks you want:
require "active_model/railtie"
require "active_job/railtie"
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_view/railtie"
# require "action_cable/engine"
# require "sprockets/railtie"
require "rails/test_unit/railtie"

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module ArtsySpace
  class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 5.1

    # 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.
  end
end

我按照以下article中的安装说明进行了安装：但是，这给我带来了问题，所以我决定删除该应用程序并从头开始。 rails _5.2.1_ new vuejs-ror-setup -M -C -S --skip-turbolinks --webpack=vue -d postgresql

通过以下方式。不确定是什么导致了这个错误？

您需要使用其他框架加载 Active Storage：

# config/application.rb
require "active_storage/engine"

'method_missing': (NoMethodError) 的未定义方法“active_storage”

'method_missing': undefined method `active_storage' for (NoMethodError)
