我在我的用户头像应用程序上使用paperclip（4.2）。当我将我的头像从'me.jpg'更新为'you.jpg'时，终端会抛出错误ActionController::RoutingError (No route matches [GET] "/system/users/avatars/000/000/010/original/me.jpg")
虚拟形象上传然而它不会像它应该的那样加载。我在我的顶栏中有一个恒定的current_user图像，当我从me.jpg更新到you.jpg时，图像变成了一个代表它未找到的图标。一旦我重新加载页面，图像就会出现。

注意：我没有手动设置回形针的任何路径。从我看到的，当我上传'you.jpg'时，它上传它并替换'me.jpg'，然后在终端抱怨我想，因为它试图找到'me.jpg'仍然？为什么，我不知道，我不确定这是不是问题。任何帮助将不胜感激，谢谢。
