Heroku Asset_sync Gem不上传到S3

Question

当我预编译资产

时，我的Asset_sync Gem不会上传到S3

Asset_sync.rb

if defined?(AssetSync)
  AssetSync.configure do |config|
    config.fog_provider = 'AWS'
    config.aws_access_key_id = ENV['AWS_ACCESS_KEY_ID']
    config.aws_secret_access_key = ENV['AWS_SECRET_ACCESS_KEY']
    # To use AWS reduced redundancy storage.
    # config.aws_reduced_redundancy = true
    config.fog_directory = ENV['FOG_DIRECTORY']
    # Invalidate a file on a cdn after uploading files
    # config.cdn_distribution_id = "12345"
    # config.invalidate = ['file1.js']
    # Increase upload performance by configuring your region
    config.fog_region = 'ap-southeast-2'
    #
    # Don't delete files from the store
    # config.existing_remote_files = "keep"
    #
    # Automatically replace files with their equivalent gzip compressed version
    # config.gzip_compression = true
    #
    # Use the Rails generated 'manifest.yml' file to produce the list of files to
    # upload instead of searching the assets directory.
    # config.manifest = true
    #
    # Fail silently.  Useful for environments such as Heroku
    # config.fail_silently = true
  end
end

production.rb

  config.assets.enabled = true
  config.assets.digest = true
  config.action_controller.asset_host = "//#{ENV['FOG_DIRECTORY']}.s3.amazonaws.com"
  config.assets.initialize_on_precompile = true

application.rb

    config.assets.enabled = true
    config.assets.digest = true

当我预编译时，我什至没有收到任何消息来显示它正在上传。

有什么原因发生的原因？

Answer 1

可能是：

group :assets do
  gem 'asset_sync'
end

您应该从该组中删除该宝石

Answer 2

我知道这个问题是旧的...但是我只是继承了一个Heroku应用程序，并且正在阅读如何与Heroku进行资产并遇到此问题，这表明在编译资产时，ENV变量是不可用的在Heroku。
