I had the same problem, make sure you activated virtualenv, since once you close cmd it is no longer activated:
我遇到了同样的问题，请确保您激活了 virtualenv，因为一旦您关闭 cmd 它就不再被激活：
env\Scripts\activatein cmd
env\Scripts\activate在 cmd 中
Now cmd should have (env) just like this: (env) c:\users\user\PROJECT\..
现在 cmd 应该有 (env) 就像这样： (env) c:\users\user\PROJECT\..
Now you can type: python manage.py runserver
现在你可以输入： python manage.py runserver

sys.path.append('/Users/et/PycharmProjects/Jieba_Analyzer/venv/lib/python3.6/site-packages')

管理.py
