OSError：无法识别图像文件＆lt; _io.BytesIO对象0x000001C4EA23AE08＆gt;

Question

当我使用scrapy.pipelines.images.ImagesPipeline下载图片时，我收到错误;

错误代码返回

  Traceback (most recent call last):
  File "C:\Users\\AppData\Local\Programs\Python\Python36\lib\site-packages\scrapy\pipelines\files.py", line 401, in media_downloaded
    checksum = self.file_downloaded(response, request, info)

    orig_image = Image.open(BytesIO(response.body))
  File "C:\Users\\AppData\Local\Programs\Python\Python36\lib\site-packages\PIL\Image.py", line 2590, in open
    % (filename if filename else fp))
OSError: cannot identify image file <_io.BytesIO object at 0x0000014A3DC90728>

这是什么意思？
