我正在参加为期一个月的铁路课程，而且我的图像没有出现在本地
我收到错误消息：ActionController :: RoutingError（没有路由匹配[GET]“/ images/medium/missing.png”）：
我安装了paperclip 4.2.1。 Microsoft Window 8
我知道问题不在于文件夹中没有图像。我的图像存储在“Pinteresting”应用程序文件夹中的此文件夹中：
pinteresting /公共/系统/针/图像/ 000/000/028
在引用＃28文件夹的每个“028”内有三个子文件夹：（1）中，（2）原始，（3）拇指
Github链接：https://github.com/pfeiffer101/pinteresting/commits/master
这是我在服务器中看到的完整信息
