我的 models.py 如下，
from django.contrib.auth.models import User
from django.db import models
from django.utils.encoding import python_2_unicode_compatible
from django.utils.timezone import now
@python_2_unicode_compatible
class Tag(models.Model):
name = models.CharField(max_length=50, unique=True)
class Meta:
verbose_name = 'tag'
verbose_name_plural = 'tags'
ordering = ['name']
def __str__(self):
return self.name
............. and so on
当我运行 python manage.py syncdb 时，这是我得到的错误:
itman@itman:~/djangoApp/mysite$ python manage.py syncdb
Traceback (most recent call last):

from django.utils.encoding import python_2_unicode_compatible
ImportError: cannot import name python_2_unicode_compatible
不知道为什么没有导入模块。我正在使用 Python 2.7 和 Django 1.4。
最佳答案
最新的Django 3.0.4，和auditlog试试
from six import python_2_unicode_compatible
代替
from django.utils.six import python_2_unicode_compatible
如果没有安装运行下面的代码
pip install six
