ModuleNotFoundError：没有名为“ allauth”的模块

Question

This is my installed app.

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.sites',
    'allauth',
    'allauth.account',
    'allauth.socialaccount',
    'rest_framework',
    'rest_framework.authtoken',
    'rest_auth',
    'rest_auth.registration',

    'corsheaders',
    'articles',
]

I am using django 2.1 and rest framework.I want to implement rest auth registration. So I have followed this step by step guidelines from official documentation . When I hit enter the migrate command python manage.py migrate I am getting following error:

File "<frozen importlib._bootstrap>", line 994, in _gcd_import
  File "<frozen importlib._bootstrap>", line 971, in _find_and_load
  File "<frozen importlib._bootstrap>", line 953, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'allauth'

Answer 1

Before migrate you need to install the django rest auth packages which contain all packages including allauth

pip install django-rest-auth[with_social]

and then migrate your database.
