Question

启动了一个新的Rails项目并进行了很好的设置但是当我使用image_tag尝试显示app/assets/images中存在的图像（magnum.jpg）时出现ERROR Errno::EINVAL错误。已经有一段时间了，似乎无法过去。使用的Rails版本是4.2.3

以下是我的观点：

<div class="panel panel-default">
 <div class="panel-heading">
  <p>
    Magnum
  </p>                            
 </div>
 <div class="panel-body">
  <%= image_tag("magnum.jpg", :class => "img-responsive", :alt => "test image") %>
  <p>
    Lorem ipsum
  </p>
 </div>
</div>

这是堆栈跟踪：
