? ?1.在成功安装ImageMagick了后对图片处理是出现下面错误：?
An error was received while processing: #<Paperclip::Errors::NotIdentifiedBy ImageMagickError: Paperclip::Errors::NotIdentifiedByImageMagickError>
? ?错误解决：在Rails项目的config/environments/development.rb文件加入：
Paperclip.options[:command_path] = '/opt/local/bin/' #Mac OS 下? ? 然后重启服务器。
? ? (ps: imageMagick和Paperclip的安装请转到??http://unremittingly.iteye.com/blog/2019512)?
? ?2.用Paperclip上传的图片如何删除。
? ?
image_news_deleted = ImageNews.find(params[:id])#根据id找到对应的image_news image_news_deleted.image.destroy #删除image_news对应的存储在public文件夹下的image ImageNews.delete(params[:id]) #删除存储的image_news? ?(ps:ImageNews模型相关属性的创建请见我的?http://unremittingly.iteye.com/blog/2019512)
