所以，我一直按照这里的教程步骤进行操作 https://docs.djangoproject.com/en/1.9/intro/tutorial02/我到了应该运行此命令的步骤:

python manage.py makemigrations polls

当我运行它时，我得到了这个错误:

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:

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

这是我的模型:

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)

最佳答案

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。应该是:

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

第二个问题是警告'polls.apps' is not a package。这表明您已经安装了 Django 1.8，但您正在遵循 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，以免遇到此类问题。将投票应用添加到 INSTALLED_APPS 是 covered here在 Django 1.8 教程中。请注意，它不使用 PollsConfig。

INSTALLED_APPS = (
    ...
    'polls',
)

关于python - 没有名为 'polls.apps.PollsConfigdjango' 的模块； Django项目教程2，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35484263/
