I had a similar issue with PDFKit when I was deploying my app on Heroku. 当我在Heroku上部署我的应用程序时，我遇到了与PDFKit类似的问题。 Now, it's working fine (I've included the binary to the project). 现在，它工作正常（我已将二进制文件包含在项目中）。

In my layout: 在我的布局中：

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
  <meta http-equiv="content-type" content="text/html; charset=utf-8" />
  <title>Page title</title>
  <meta http-equiv="X-UA-Compatible" content="IE=8" />
    <%= csrf_meta_tags %>
  <style type="text/css" media="all">
    <%= Rails.application.assets['my_css'].to_s.gsub(/\/assets/,"#{root_url}assets") %>
  </style>
</head>
<body>
  <%= yield %>
</body>
</html>

In the initializers: 在初始化器中：

# config/initializers/pdfkit.rb
PDFKit.configure do |config|
  if Rails.env.staging? || Rails.env.production?
    config.wkhtmltopdf = Rails.root.join('bin', 'wkhtmltopdf-amd64').to_s
  else
    config.wkhtmltopdf = '/Users/my_user_name/.rvm/gems/ruby-1.9.2-p0@my_project/bin/wkhtmltopdf'
  end
  config.default_options = {
    :page_size => 'A4',
    :margin_top => '0in',
    :margin_right => '0in',
    :margin_bottom => '0in',
    :margin_left => '0in',
    :orientation => 'Portrait'
  }
  # Use only if your external hostname is unavailable on the server.
  config.root_url = "http://localhost:3000" unless Rails.env.staging? || Rails.env.production?
end

Maybe that could help you... or someone else... 也许这可以帮助你...或其他人......
