mongoengine.fields.ImproperlyConfigured:未找到PIL库

Question

当我试图导入一个具有MongoEngine的ImageField类时，会出现一个错误：

mongoengine.fields.ImproperlyConfigured: PIL library was not found

我的班级结构是这样的：

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

有什么问题吗？

您需要安装Pillow，它提供了PIL模块。sudo pip install Pillow (如果在sudo上删除sudo)应该这样做。
