报错原因

  File "/root/.virtualenvs/v1/lib/python3.6/site-packages/django/db/backends/mysql/base.py", line 36, in <module>
    raise ImproperlyConfigured('mysqlclient 1.3.13 or newer is required; you have %s.' % Database.__version__)
django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3.

解决方法

找到报错行

vim  /root/.virtualenvs/v1/lib/python3.6/site-packages/django/db/backends/mysql/base.py

将报错行注释掉

version = Database.version_info
#if version < (1, 3, 13):
 #   raise ImproperlyConfigured('mysqlclient 1.3.13 or newer is required; you have %s.' % Database.__version__)
