Python '；WSGIRequest&x27；对象没有属性'；模式'；添加easy_缩略图后，添加上下文

我正在尝试添加到my settings.py中的easy_thumbnails上下文处理器，出现下一个错误：

WSGIRequest'对象没有属性'mode'

上下文处理器配置：

TEMPLATES = [
    {
        ....
    'OPTIONS': {
    'context_processors': [
        ....
                'easy_thumbnails.processors.colorspace',
                'easy_thumbnails.processors.autocrop',
                'filer.thumbnail_processors.scale_and_crop_with_subject_location',
                'easy_thumbnails.processors.filters',
            ],
        },
    },
]

是的，我正在使用最新版本的枕头和简易缩略图。

对不起，我弄错了。这不是上下文处理器，而是缩略图处理器。我只想补充一点：

THUMBNAIL_PROCESSORS = (
    'easy_thumbnails.processors.colorspace',
    'easy_thumbnails.processors.autocrop',
    'easy_thumbnails.processors.filters',       
    'filer.thumbnail_processors.scale_and_crop_with_subject_location',
)

现在一切正常
