makemigrations django没有名为django.core.management的模块

Question

manage.py makemigrations 
Traceback(most recent call last):
\manage.py, line 8 in <module>
from djang.core.management import execute_from_command_line
ImportError: No module named django.core.management 

服务器仍然运行/网站将运行，但是当manage.py makemigrations运行时，会显示上述错误。
