我正在使用django和django-storage的最新版本。我正在尝试保存上传的图像和本地生成的调整大小图像。当我尝试保存图像时，出现以下错误：

从另一个stackoverflow答案中，我已将此解决方案添加到所有客户存储中：
class MediaStorage(S3Boto3Storage):
location = settings.AWS_MEDIA_LOCATION
default_acl = 'public-read'
file_overwrite = False
def _clean_name(self, name):
return name
def _normalize_name(self, name):
if not name.endswith('/'):
name += "/"
name += self.location
return name
然后我收到此错误：
