application.html.erb

<!DOCTYPE html>
<html>
  <head>
    <title><%= full_title(yield(:title)) %></title>
    <%= stylesheet_link_tag    "application", media: "all" %>
    <%= javascript_include_tag "application" %>
    <%= csrf_meta_tags %>
    <%= render 'layouts/shim' %>
  </head>
  <body>
    <%= render 'layouts/header' %>
    <div class="container">

      <% flash.each do |key, value| %>
        <div class="alert alert-"<%= key %>"><%= value %></div>
      <% end %>

      <%= yield %>
      <%= render 'layouts/footer' %>
      <%= debug(params) if Rails.env.development? %>
    </div>
  </body>
</html>

我试过手动硬编码

<div class="alert alert-success">Welcome</div>

这导致测试通过，所以我排除了user_pages_spec文件。不知道错误在哪里，因为它在注册时打印成功消息。

看起来你有额外的报价

<div class="alert alert-"<%= key %>"><%= value %></div>

应该是

<div class="alert alert-<%= key %>"><%= value %></div>
