命令失败(exitstatus=1)：--加载-错误处理忽略--标头-html

Question

我使用PDFKit gem在Rails中生成PDFs，我试图在我的PDF中添加一个头文件，我尝试在生成PDF时使用header_html，但以错误告终

下面是错误：

RuntimeError - command failed (exitstatus=1): /usr/bin/wkhtmltopdf --page-size Letter --encoding UTF-8 --load-error-handling ignore --header-html 

下面是我的代码：

    view_generator = ActionView::Base.new(Rails.root.join('app/views'))
    pdf_kit = PDFKit.new(view_generator.render(partial: 'field_set_answers/pdf_feedback', locals: { field_set_answer: self }, formats: [:html], layout: false).html_safe, header_html: Rails.root + 'app/views/field_set_answers/pdf_header.html.haml')
    pdf_kit.stylesheets << "#{Rails.root}/public/stylesheets/feedback.css"
    file_name = "feedback_#{Time.now.to_i}.pdf"
    file_path = "#{Rails.root}/tmp/#{file_name}"
    file = pdf_kit.to_file(file_path)

你试过这样的东西吗？

pdf_kit = PDFKit.new(view_generator.render(partial: 'field_set_answers/pdf_feedback', :header_center => "foo", locals: { field_set_answer: self }, formats: [:html], layout: false).html_safe, header_html: Rails.root + 'app/views/field_set_answers/pdf_header.html.haml')
