LoadError while 运行 rails active_storage:install

Question

我是 rails 上 ruby 的新手，我正在尝试构建一个基本的待办事项列表应用程序。我的 ruby 版本是 2.5.5，Rails 版本是 5.1.7。我正在尝试在我的应用程序中设置 active_storage，但无法运行命令 rails active_storage:install。我在 Windows 8.1 x64 系统上。

这是错误轨迹：

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

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

我已经尝试将 require active_storage/engine 包含在我的 config/application.rb 文件中，但它不起作用。

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

我需要在我的架构中创建 2 个表：active_storage_blobs 和 active_storage_attachments 运行宁 rails db:migrate。将不胜感激关于如何让它工作的任何帮助。谢谢！

支持活动存储，默认来自 Rails 版本 >= 5.2。您的 Rails 版本是 5.1.7.

因此，您应该考虑将您的应用升级到 Rails 5.2(See this link) 以使用活动存储。
