我的 pdf 在本地正确生成，有时在我的 Heroku 应用程序中生成，但有时它们会超时，我会看到这个错误

经过进一步审查。您不需要 2 个网络测功机。只需确保将 CSS 包含在 application.html.erb 文件夹和您的 file_name.pdf.erb 中即可。

这是我的 application.html.erb 文件。 

<% if request_from_pdfkit? %>
            <!-- css for pdf -->
                <style type="text/css">
                    <%= File.read(Rails.root.join("public","stylesheets","invoice_pdf.css.scss"))%>
                    <%= File.read(Rails.root.join("public","stylesheets","app.css.scss"))%>
                </style>
            <% end %>

任何然后我的 .pdf.erb 文件

<!DOCTYPE html>
<html>
<head>
  <title><%= title %></title>
    <style type="text/css">
        <%= Printavo::Application.assets["invoice_pdf.css.scss"].to_s.html_safe %>
        <%= Printavo::Application.assets["app.css.scss"].to_s.html_safe %>
        body{ font-family: arial !important;}
    </style>
</head>

2 web dynos 修复了这个问题或者使用了delayed_jobs gem。还要确保在生成的 PDF 中包含 CSS。
