ruby-on-rails - 安装 fog gem 服务器后无法启动

Question

我安装了 carrierwave gem 和 fog gem 以使用 Amazon s3。但是，在完成所有步骤之后，我尝试运行 rails s -p $PORT -b $IP 因为我使用的是 cloud9。服务器没有启动!仅供引用，我使用 postgresql 作为我的数据库。

这是错误的一部分:

=> Booting WEBrick
=> Rails 4.2.5 application starting in development on http://0.0.0.0:8080
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server

这里是我的 image_uploader:

class ImageUploader < CarrierWave::Uploader::Base


  storage :fog
  # storage :fog
  include CarrierWave :MimeTypes
  process :set_content_type


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


end

我的carrierwave.rb:

CarrierWave.configure do |config|
  config.fog_credentials = {
    provider:              'AWS',                        # required
    aws_access_key_id:     ENV["S3_ACCESS_KEY"],                        # required
    aws_secret_access_key: ENV["S3_SECRET_KEY"]                      # required
  }
  config.fog_directory  = ENV["S3_BUCKET"]                          # required
end

fog 似乎没有在您的 Gemfile.lock 中列出。

确保将此添加到 Gemfile 的根级别:

gem 'fog', '~> 1.38'

然后运行:

bundle install

并提交更改。

重新启动应用程序，它应该可以工作。
