环境DJANGO VERSION 1.9 Python 2.7.6

我在models.py这样的模型类中添加了一个字段(分数)

from django.db import models
from django.contrib.auth.models import User
import urllib
import hashlib


class profile(models.Model):
    user = models.OneToOneField(User)
    nickname = models.CharField(max_length=12, blank=True, null=True)
    use_gravatar = models.BooleanField(default=True)
    location = models.CharField(max_length=20, blank=True, null=True)
    avatar_url = models.URLField(blank=True, null=True)
    website = models.URLField(blank=True, null=True)
    **scores = models.IntegerField(default = 0)**  

我运行以下命令来同步数据库.

python manage.py makemigrations
python manage.py migrate

但得到了这个

OperationalError at /
no such column: account_profile.scores
Request Method: GET
Request URL:    http://127.0.0.1:8000/
Django Version: 1.8.4
Exception Type: OperationalError
Exception Value:    
no such …

在终端,我可以py -2成功运行.尽管如此,

C:\Users\user>py -3
