django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3.
解決辦法：
修改/usr/local/lib/python3.5/dist-packages/django/db/backends/mysql/base.py文件，注釋掉：
if version < (1, 3, 13):
raise ImproperlyConfigured('mysqlclient 1.3.13 or newer is required; you have %s.' % Database.__version__)
