如何修复运行Django Test时找不到模块错误

Question

我正在尝试为我的博客应用程序运行一些简单的测试。我安装了social_django是因为我希望用户能够使用其Facebook，Twitter或Google帐户登录。

使用python manage.py test运行测试时，出现此错误。

Traceback (most recent call last):

ModuleNotFoundError: No module named 'social_django'

这是我的测试代码。我正在使用在“应用”中创建的默认tests.py文件。

from django.test import TestCase
from christian_blog_app.models import Post
from django.utils import timezone
from django.core.urlresolvers import reverse
from christian_blog.settings import social_django, crispy_forms, coverage, social_login

# Create your tests here.

class PostTest(TestCase):

    def create_post(self, title="only a test", body="Testing if the created title matches the expected title"):
        return Post.objects.create(title=title, body=body, created_at=timezone.now())

    def test_post_creation(self):
        w = self.create_post()
        self.assertTrue(isinstance(w, Post))
        self.assertEqual(w.__str__(), w.title)

您认为我做错了什么？我该如何解决？

Answer 1

您应该检查是否在settings.py中将“ social_django”添加到INSTALLED_APPS中。

Answer 2

我不得不再次安装social_django和其他一些应用。它解决了问题。
