Не импортируется Django

Не импортируется Django . Вот ошибка:

    File "manage.py", line 17, in <module>
        "Couldn't import Django. Are you sure it's installed and "
    ImportError: Couldn't import Django. Are you sure it's installed and available
    on your PYTHONPATH environment variable? Did you forget to activate
    a virtual environment?
Полная ошибка:
Traceback (most recent call last):
  File "manage.py", line 8, in <module>
    from django.core.management import execute_from_command_line
ModuleNotFoundError: No module named 'django'
