Question

我是不熟悉ruby的人，正在尝试构建一个基本的待办事项列表应用程序。我的红宝石版本是2.5.5，Rails版本是5.1.7。我正在尝试在应用程序中设置active_storage，但是无法运行命令rails active_storage:install。我在Windows 8.1 x64系统上。

这是错误跟踪：

C:\Users\Sreekar\Documents\GitHub\todo-app>rails active_storage:install --trace

bin/rails:4:in `<main>'

我已经尝试在我的require active_storage/engine文件中包含config/application.rb，但是它不起作用。

这些是我的application.rb文件的内容：

require_relative 'boot'
require 'rails/all'
require 'active_storage/engine'

Bundler.require(*Rails.groups)

module TodoApp
class Application < Rails::Application
config.load_defaults 5.1

我需要在模式active_storage_blobs中创建两个表：active_storage_attachments和rails db:migrate。感谢您提供有关如何使其正常工作的帮助。谢谢！

支持活动存储，默认情况下它们是Rails版本> = 5.2中的版本。您的Rails版本是5.1.7。

因此，您应该考虑将应用程序升级到Rails 5.2（See this link）以使用活动存储。

运行Rails active_storage：install时发生LoadError
