Heroku：在 /app/config/storage.yml 中找不到 Active Storage 配置（运行时错误）

Question

我的应用程序部署到 Heroku，但每次都崩溃。我不知道为什么。我已经在 Heroku 上为生产中的应用程序设置了 Carrierwave、雾和 aws，然后就好了。尝试按照相同的步骤操作，但我收到了 h10 错误代码。在 rails 控制台中，它特别指出：

/app/vendor/bundle/ruby/2.3.0/gems/activestorage-5.2.1/lib/active_storage/engine.rb:76:in `block (2 levels) in ': 找不到 Active Storage 配置 / app/config/storage.yml（运行时错误）

storage.yml 

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

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


# Use rails credentials:edit to set the AWS secrets (as aws:access_key_id|secret_access_key)
# amazon:
amazon:
  service: S3
  access_key_id: "S3_KEY"
  secret_access_key: "S3_SECRET"
  region: "us-east-1"
  bucket: "books4reviews"

生产.rb

  config.active_storage.service = :amazon 

载波

CarrierWave.configure do |config|

config.fog_provider = 'fog/aws'

config.fog_credentials = {
  provider: 'AWS',
  aws_access_key_id: ENV['S3_KEY'],
  aws_secret_access_key: ENV['S3_SECRET'],
  region: 'us-east-1'
}
config.fog_directory  = 'books4reviews'
config.fog_public = false
config.storage = :fog
end

threads_count = ENV.fetch("RAILS_MAX_THREADS") { 5 }

    port        ENV.fetch("PORT") { 3000 }

   environment ENV.fetch("RAILS_ENV") { "development" }

配置文件

头像_上传者.rb

class AvatarUploader < CarrierWave::Uploader::Base
  # Include RMagick or MiniMagick support:
  # include CarrierWave::RMagick
  # Choose what kind of storage to use for this uploader:
  include CarrierWave::MiniMagick

  storage :fog

  process resize_to_fit: [500,500]

  version :small do
    process resize_to_fill: [200, 200]
  end

  version :medium do

      # change the word 'fit' to 'fill'
      process resize_to_fill: [400,600]
  end

  version :large do
    process resize_to_fill: [1000,1000]
  end

  version :thumb do
    process resize_to_fill: [50, 50]
  end

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  def extension_white_list
    %w(jpg jpeg gif png)
  end

end

我已经在终端的 heroku 配置变量中为 aws 凭证设置了我的 env 变量。你能告诉我为什么我会收到这个活动存储错误吗？谢谢

我在部署最近升级的 Rails 应用程序时遇到了同样的问题。应用程序从Rails 5升级到Rails 6。但是，当我尝试部署到Heroku 时，出现以下错误：

2021-02-12T17:32:33.404828+00:00 app[web.1]: ! Unable to load application: RuntimeError: Couldn't find Active Storage configuration in /app/config/storage.yml
2021-02-12T17:32:33.404874+00:00 app[web.1]: bundler: failed to load command: puma (/app/vendor/bundle/ruby/2.7.0/bin/puma)
2021-02-12T17:32:33.404958+00:00 app[web.1]: RuntimeError: Couldn't find Active Storage configuration in /app/config/storage.yml

这是我修复它的方法：

我检查了config我的应用程序的目录，发现它没有config/storage.yml文件。我所要做的就是创建文件，并将Rails 6应用程序附带的 vanilla 模板复制到文件中：

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

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

# Use rails credentials:edit to set the AWS secrets (as aws:access_key_id|secret_access_key)
# amazon:
#   service: S3
#   access_key_id: <%= Rails.application.credentials.dig(:aws, :access_key_id) %>
#   secret_access_key: <%= Rails.application.credentials.dig(:aws, :secret_access_key) %>
#   region: us-east-1
#   bucket: your_own_bucket

# Remember not to checkin your GCS keyfile to a repository
# google:
#   service: GCS
#   project: your_project
#   credentials: <%= Rails.root.join("path/to/gcs.keyfile") %>
#   bucket: your_own_bucket

# Use rails credentials:edit to set the Azure Storage secret (as azure_storage:storage_access_key)
# microsoft:
#   service: AzureStorage
#   storage_account_name: your_account_name
#   storage_access_key: <%= Rails.application.credentials.dig(:azure_storage, :storage_access_key) %>
#   container: your_container_name

# mirror:
#   service: Mirror
#   primary: local
#   mirrors: [ amazon, google, microsoft ]

这次我部署一切正常。

注意：您可以根据您的存储配置修改文件内容

就这样。

我希望这有帮助

这可能无法解决您的问题，但我有“.yaml”而不是“.yml”，因为我必须手动创建文件“/config/storage.yml”并犯了一个拼写错误。

希望这对某人有帮助，因为我找不到有关此错误的很多结果。

仅供参考，我认为生成器没有创建 storage.yml 文件，因为我最初使用的是 Rails 5.1，然后升级到 5.2
