Bootstrap 下拉菜单不显示

新手跟着《Ruby on Rails 教程》一直做到第八章尾，但是有个问题实在解决不了，特来请教各位大大。

app/views/layouts/_header.html.erb

<header class="navbar navbar-fixed-top navbar-inverse">
  <div class="container">
    <%= link_to "sample app", root_path, id: "logo" %>
    <nav>
      <ul class="nav navbar-nav navbar-right">
        <li><%= link_to "Home", root_path %></li>
        <li><%= link_to "Help", help_path %></li>
        <% if logged_in? %>
          <li><%= link_to "Users", '#' %></li>
          <li class="dropdown">
            <a href="#" class="dropdown-toggle" data_toggle="dropdown">
              Account <b class="caret"></b>
            </a>
            <ul class="dropdown-menu">
              <li><%= link_to "Profile", current_user %></li>
              <li><%= link_to "Settings", '#' %></li>
              <li class="divider"></li>
              <li>
                <%= link_to "Log out", logout_path, method: "delete" %>
              </li>
            </ul>
          </li>
        <% else %>
          <li><%= link_to "Log in", login_path %></li>
        <% end %>
      </ul>
    </nav>
  </div>
</header>

但是其中的下拉菜单一直都不能显示，对着书看了几遍都没找出写错的地方。

这是部署在 heroku 上的应用，各位可以用下面的账号来测试右上角的下拉菜单...

如果问题太菜请猛烈的拍，我能扛得住..
