No module named 'polls.apps.PollsConfigdjango'; Django project tutorial 2
So, I've been following the tutorial steps here https://docs.djangoproject.com/en/1.9/intro/tutorial02/ and I got to the step where I am supposed to run this command:
python manage.py makemigrations polls
When I run it, I get this error:
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
Here are my models:
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)
The first problem is this warning in the traceback:
No module named 'polls.apps.PollsConfigdjango'
That means that you are missing a comma after 'polls.apps.PollsConfig in your INSTALLED_APPS setting. It should be:
INSTALLED_APPS = (
...
'polls.apps.PollsConfig',
'django....',
...
)
The second problem is the warning 'polls.apps' is not a package . That suggests that you have installed Django 1.8, but you are following the Django 1.9 tutorial.
If you are using Django 1.8, then follow the 1.8 tutorial so that you don't hit problems like this. Adding the polls app to INSTALLED_APPS is covered here in the Django 1.8 tutorial. Note that it doesn't use PollsConfig .
INSTALLED_APPS = (
...
'polls',
)
在'polls.apps.PollsConfigdjango'之后检查逗号“，”
ImportError: No module named 'polls.apps.PollsConfigdjango'
你忘了在列表中添加'，'
