Question

所以我们已经在许多地方工作了没有问题。当地的工作就像一个魅力。但是最后两个地方我们已经部署了我们的应用程序，我们安装了wkhtmltopdf并且无法让wicked_pdf正常工作。

wkhtmltopdf位置：

$ which wkhtmltopdf
=> /usr/local/bin/wkhtmltopdf

我们的wicked_pdf配置：

WickedPdf.config = {
  :exe_path => '/usr/local/bin/wkhtmltopdf'
}

错误：

RuntimeError (Failed to execute:
"/usr/local/bin/wkhtmltopdf" -q  --footer-html "file:///tmp/wicked_footer_pdf.html20140604-7480-1ag3z4u"    --margin-top 20 --margin-bottom 40  --page-size "Letter" --encoding "utf8" --print-media-type    - -
Error: PDF could not be generated!):
  app/controllers/concerns/downloadable_controller.rb:20:in `block (2 levels) in download'
  app/controllers/concerns/downloadable_controller.rb:18:in `download'

我开始认为它的wkhtmltopdf更新版本的b / c或者最后部署的b / c比以前工作正常的更新。但是这些较新的服务器是64位系统而不是以前的服务器的32位。

经过一些进一步的测试后，我发现它的页脚打破了整个事情，但我无法弄清楚原因。

  def download
    # build resources such as @letter or @study to be used in view
    build_resources_for_pdf

    respond_to do |format|
      format.pdf do
        render :pdf => file_name,
               :template => "/#{model}/pdf/show.haml",
               :encoding => "utf8",
               :page_size => "Letter",
               :show_as_html => params[:debug].present?,
               :print_media_type => true,
               :margin => { :bottom => 40, :top => 20 },
               :footer => get_footer

      end
    end
  end

  def get_footer
    {
      :html => {
        :template => "studies/pdf/pdf_footer",
        :locals => {:study => @study}
      }
    }
  end

生产中的Wicked_pdf和wkhtmltopdf
