Bobby老师，我在设置好settings.py文件后，在cmd运行，出现错误了，报错如下：C:\Users\Administrator\PycharmProjects\MxOnline>python manage.py runserver 0.0.0.0:8000

Traceback (most recent call last):

  File "manage.py", line 8, in <module>

    from django.core.management import execute_from_command_line

ImportError: No module named django.core.management

我的settings.py文件设置如下：

import os

import sys

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.insert(0, os.path.join(BASE_DIR, 'apps'))

但是我进入虚拟环境以后，又可以运行：

C:\Users\Administrator\PycharmProjects\MxOnline>workon

Pass a name to activate one of the following virtualenvs:

mxonline

testvir2

C:\Users\Administrator\PycharmProjects\MxOnline>workon mxonline

(mxonline) C:\Users\Administrator\PycharmProjects\MxOnline>python manage.py runserver 0.0.0.0:8000
