无法自动加载常量ActiveStorage::Blob::Analyzable

Question

我查看了关于这个错误的每一个可能的解决方案，但是没有解决它。

每当我试图上传图片时，我都会收到以下错误：

Unable to autoload constant ActiveStorage::Blob::Analyzable, expected /usr/local/lib/ruby/gems/2.5.0/gems/activestorage-5.2.2/app/models/active_storage/blob/analyzable.rb to define it。

在config/application.rb中，require 'active_storage/engine'没有注释。

在config/environments/development.rb中，我设置了config.active_storage.service = :local。

我负责rails active_storage:install和rails db:migrate。

模型的名称是user_test

class UserTest < ApplicationRecord
  has_one_attached :image
end

我在app/controllers/user_tests_controller.rb里有这个

def user_test_params
  params.require(:user_test).permit(:title, :caption, :image)
end 

**config/storage.yml*

test:
  service: Disk
  root: <%= Rails.root.join("tmp/storage") %>

local:
  service: Disk
  root: <%= Rails.root.join("storage") %>

我真的不知道为什么它不起作用。

Answer 1

您的development.rb中有设置development.rb的可能性吗？

我得到了上面的错误，结果是因为我有上面的行，但是AWS env没有设置。

Answer 2

请确保检查所有环境变量是否都存在：

• AWS访问密钥
• AWS密钥
• 桶名

检查环境变量的拼写，以确保它们与storage.yml配置文件匹配。
