Paperclip在允许将文件附加到模型之前验证mime类型。浏览器通常会发送一个mime类型（它认为文件是什么），在你的情况下，它是＆＃39; image / png＆＃39;对于第一个文件和＆＃39; application / octet-stream＆＃39;为第二个文件。但是因为mime类型欺骗是一种东西，回形针试图通过运行＆＃39;文件来确定mime类型本身。命令对文件。在您的情况下，该命令返回两个文件的空字符串：

, content type discovered from file command: . See documentation to allow this combination.

＆＃39;命令之间的空格：＆＃39;和＆＃39;。＆＃39;是文件命令返回的内容。

我的猜测是：您在Windows上运行并且没有安装它，或者无法找到它。关注these instructions for exactly that case on the paperclip website。
