Rails 4 中的 Paperclip::Errors::NotIdentifiedByImageMagickError [英] Paperclip::Errors::NotIdentifiedByImageMagickError in Rails 4

问题描述

有以下模型:

class Picture < ActiveRecord::Base
  belongs_to :business

  has_attached_file    :image, styles: { medium: "640x260>" }
  validates_attachment :image, content_type: { :content_type => /\Aimage\/.*\Z/ }
end

此外，我还使用 brew(我使用 Mac OS)安装了imagemagick".但是当我尝试执行以下代码时

Also I've installed 'imagemagick' using brew (I use Mac OS). But when I was trying to execute the following code

@picture = business.pictures.build(picture_params)
@picture.save

def picture_params
    params.require(:picture).permit(:image)
end

我收到以下错误:处理时收到错误:#<Paperclip::Errors::NotIdentifiedByImageMagickError: Paperclip::Errors::NotIdentifiedByImageMagickError>

我正在尝试更新 PNG 文件:

I was trying to update PNG file:

= form_for [:admin, business, @picture] do |f|
    .row
        = f.file_field :image
        = f.submit 'Add'

我该如何解决我的问题?

How can I fix my problem?
