我已经将我的 rails api 应用程序从 5.1 更新到 5.2。 我只使用轨道 api。 我正在尝试使用活动存储。我认为问题是由于config/application.rb中的线路config.api_only = true.
我做了很多谷歌，但没有找到任何如何在 rails api 中使用活动存储的东西。
这是我Gemfile：
source 'https://rubygems.org'
ruby '2.5.1'
git_source(:github) do |repo_name|
repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
"https://github.com/#{repo_name}.git"
end
gem 'rails', '~> 5.2.0'
gem 'pg', '>= 0.18', '< 2.0'
gem 'puma', '~> 3.7'
gem 'rack-cors'
# Auth
gem 'bcrypt'
gem 'jwt'
#Media file upload
gem 'activestorage'
# gem 'devise', '4.4.3'
# gem 'devise-jwt', '~> 0.5.6'
gem 'active_model_serializers', '~> 0.10.0', require: true
# backgroud jobs
gem 'sidekiq'
# fast boot
gem 'bootsnap', require: false
group :development, :test do
gem 'rspec-rails', '~> 3.7'
gem 'brakeman'
gem 'rubocop'
gem 'byebug', platforms: [:mri, :mingw, :x64_mingw]
end
group :development do
gem 'foreman'
gem 'listen', '>= 3.0.5', '< 3.2'
gem 'spring'
gem 'pry'
gem 'spring-watcher-listen', '~> 2.0.0'
gem 'annotate'
end
# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
这是我的config/application.rb
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 "active_storage"
# 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 CelebrationBackend
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.
# Only loads a smaller set of middleware suitable for API only apps.
# Middleware like session, flash, cookies can be added back manually.
# Skip views, helpers and assets when generating a new resource.
config.api_only = true
config.active_job.queue_adapter = :sidekiq
config.autoload_paths << Rails.root.join('lib')
end
end
在控制台中运行rails activestorage:install时。 我收到以下错误：

我没有得到我做错了什么的确切事情。
你的问题在这里：
require "active_storage"
您需要要求引擎：
require "active_storage/engine"
目前的rails官方文件谈到了这个新的应用程序。但如果要升级 5.2 之前的应用，则必须在application.rb中添加或取消注释该字段
require "active_storage/engine"
对于新应用程序，这将已添加。
尝试在项目根目录中运行命令
bin/rails active_storage:install
或
rake active_storage:install
