尝试使用 S3 通过 React on Rails 上传文件

Question

所以我正在关注这篇文章https://medium.com/@andrea.wayte/using-amazon-s3-to-store-images-for-react-on-rails-b1414ba2c0b2。每当我在更新数据库后迁移数据库时，我都会收到此错误。

admins-MBP:direct-s3-example admin$ rake db:migrate
rake aborted!
NameError: undefined local variable or method `config' for main:Object
/Users/admin/direct-s3-example/config/environments/development.rb:65:in `<main>'

(See full trace by running task with --trace)

我没有 environment.rb 文件，但这是我的 development.rb 文件。

Rails.application.configure do
  # Settings specified here will take precedence over those in config/application.rb.

  # every request. This slows down response time but is perfect for development
  # since you don't have to restart the web server when you make code changes.
  config.cache_classes = false

  # Do not eager load code on boot.
  config.eager_load = false

  # Show full error reports.

  if Rails.root.join('tmp', 'caching-dev.txt').exist?
    config.action_controller.perform_caching = true
    config.action_controller.enable_fragment_cache_logging = true

    config.cache_store = :memory_store
    config.public_file_server.headers = {

    }

    config.action_controller.perform_caching = false

  # Raise an error on page load if there are pending migrations.

  # Debug mode disables concatenation and preprocessing of assets.
  # This option may cause significant delays in view rendering with a large

  config.assets.debug = true

  # Suppress logger output for asset requests.
  config.assets.quiet = true

  # Raises error for missing translations.
  # config.action_view.raise_on_missing_translations = true

  # Use an evented file watcher to asynchronously detect changes in source code,
  # routes, locales, etc. This feature depends on the listen gem.
  config.file_watcher = ActiveSupport::EventedFileUpdateChecker
end

Paperclip.options[:command_path] = "/usr/bin/"
config.paperclip_defaults = {
    storage: :s3,
    s3_host_name: 's3-us-east-2.amazonaws.com',
    s3_credentials: {
       bucket: ENV.fetch('petition-form'),
       access_key_id: ENV.fetch('--------'),
       secret_access_key: ENV.fetch('--------------'),
       s3_region: ENV.fetch('us-east-2'),
    }
}
