所以，我一直在按照这里的教程步骤https://docs.djangoproject.com/en/1.9/intro/tutorial02/进行我应该运行此命令的步骤：

python manage.py makemigrations polls

当我运行它时，我收到此错误：

python manage.py makemigrations polls
Traceback (most recent call last):
  File "<frozen importlib._bootstrap>", line 2218, in_find_and_load_unlocked
AttributeError: 'module' object has no attribute '__path__'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/home/tgumm/pythonenv/tutorial/lib/python3.4/site-packages/django/core/management/__init__.py", line 353, in execute_from_command_line

ImportError: No module named 'polls.apps.PollsConfigdjango'; 'polls.apps' is not a package

这是我的模特：

from django.db import models

# Create your models here.
from django.db import models


class Question(models.Model):
    question_text = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')


class Choice(models.Model):
    question = models.ForeignKey(Question, on_delete=models.CASCADE)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField(default=0)
python django

    第一个问题是回溯中的这个警告：

    No module named 'polls.apps.PollsConfigdjango'

    这意味着您在 INSTALLED_APPS 设置中的 'polls.apps.PollsConfig 之后缺少逗号 . 它应该是：

    INSTALLED_APPS = (
    ...
    'polls.apps.PollsConfig',
    'django....',
    ...
)

    第二个问题是警告 'polls.apps' is not a package . 这表明你已经安装了Django 1.8，但是你正在关注Django 1.9教程 .

    如果您使用的是Django 1.8，请按照1.8教程进行操作，这样就不会遇到类似的问题 . 在Django 1.8教程中将民意调查应用程序添加到 INSTALLED_APPS 是covered here . 请注意，它不使用 PollsConfig .

    INSTALLED_APPS = (
    ...
    'polls',
)

    引用自https://code.djangoproject.com/ticket/27139

    描述

    在教程02中，编写您的第一个Django应用程序，第2部分，输入

    INSTALLED_APPS = [
    'polls.apps.PollsConfig',
   ....

    将导致ImportError：没有名为'polls.apps.PollsConfig'的模块; 'polls.apps'不是一个包

    这可以通过改为解决

    INSTALLED_APPS = [
    'polls',
   ....

    我收到了类似的错误： ImportError: No module named 'polls'

    原因是我将我的应用程序存储在“apps”目录中 . 解决方案是更改apps.py中的代码

    从：

    class PollsConfig(AppConfig):
    name = 'polls'

    to（“apps”是我的django apps目录的名称）：

    class PollsConfig(AppConfig):
    name = 'apps.polls'
