那就是我在modeles.py中的代码
from django.db import models
from django.utils import timezone
class Book(models.Model):
title = models.CharField(max_length = 200)
author = models.CharField(max_lenght = 200)
description = models.TextField()
publish_date = models.DateField(Default= timezone.now)
那就是当我键入./manage.py makemigrations执行错误时
，这就是我在嘘中看到的错误，仍然没有控制空间可知，当我将鼠标指向django的鼠标指针时，它出现了无法解析的参考“ django”，而我安装了它pip install django == 1.8并且每次运行sudo pip install --ignore-installed virtualenvwrapper时都会运行，因为当我使用workon bookstore-django时，它不会执行，直到我运行sudo pip install --ignore-installed virtualenvwrapper，我也是该领域的初学者
(bookstore-django) bavlys-Mac:bookstore bavlymorcos$ ./manage.py makemigrations store

我解决了这个问题，谢谢大家
问题出在model.py中，我将其更改为
from django.db import models
from django.utils import timezone
class Book(models.Model):
title = models.CharField(max_length=200)
author = models.CharField(max_length=200)
description = models.TextField()
publish_date = models.DateField(default=timezone.now)
