Rails 中的 Rmagick Carrierwave - 可以启动服务器

Question

我正在关注this 教程（railscast 载波）。我可以显示图像，就像这里的许多其他线程一样，但是我在安装 rmagick 时遇到了问题。

我已尝试按照here的建议卸载并重新安装 imagemagick 和 rmagick...

将 rmagick 添加到我的 gemfile 后，我无法再在开发中启动我的应用程序。

错误日志如下

这里是我的载波上传器的配置

class ImageUploader < CarrierWave::Uploader::Base



# Include RMagick or MiniMagick support:
  include CarrierWave::RMagick
  # include CarrierWave::MiniMagick

  # Choose what kind of storage to use for this uploader:
  storage :file
  # storage :fog

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  # Provide a default URL as a default if there hasn't been a file uploaded:
  # def default_url
  #   # For Rails 3.1+ asset pipeline compatibility:
  #   # ActionController::Base.helpers.asset_path("fallback/" + [version_name, "default.png"].compact.join('_'))
  #
  #   "/images/fallback/" + [version_name, "default.png"].compact.join('_')
  # end

  # Process files as they are uploaded:
  # process :scale => [200, 300]
  #
  # def scale(width, height)
  #   # do something
  # end

  # Create different versions of your uploaded files:
  version :thumb do
    process :resize_to_limit => [150, 150]
  end

  # Add a white list of extensions which are allowed to be uploaded.
  # For images you might use something like this:
  # def extension_white_list
  #   %w(jpg jpeg gif png)
  # end

  # Override the filename of the uploaded files:
  # Avoid using model.id or version_name here, see uploader/store.rb for details.
  # def filename
  #   "something.jpg" if original_filename
  # end

end

我正在运行 Mac OSX 10.8.5....

任何帮助将不胜感激。提前致谢！

尝试使用 mini-magick 代替 rmagick ：

评论下面一行：

包括 CarrierWave::RMagick

并使用下面的

包括 CarrierWave::MiniMagick

宝石文件：
