python – mongoengine.fields.ImproperlyConfigured：找不到PIL库

当我尝试导入具有ImageField的MongoEngine类时,错误说：

mongoengine.fields.ImproperlyConfigured: PIL library was not found

我的类结构是这样的：

class TrafficSign(Document):
    name = StringField()
    image = ImageField()
    type = StringField()
    desc = StringField()
    source = StringField()

有什么问题？

解决方法:

您需要安装Pillow,它提供PIL模块. sudo pip install Pillow(如果在Windows上放弃sudo)应该这样做.
