Django2.2报错 django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3.

Django2.2报错 django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3.

准备将 Django 连接到 MySQL，在命令行输入命令 python manage.py makemigrations 后报错： django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3.
由于 mysqlclient 目前不支持高版本python，出现这个错误之后可以根据错误提示找到文件位置，打开 base.py 文件，找到以下代码：

/Users/vickytu/Documents/INSTALL/anaconda3/lib/python3.6/site-packages/django/db/backends/mysql/base.py    #本机目录

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

将 if 语句注释掉之后在执行命令就不会再报错

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

此时仍会会报错，报错信息如下：

AttributeError: ‘str’ object has no attribute ‘decode’

#找到operations.py文件（146行），将decode改为encode
#linux vim 查找快捷键：？decode
if query is not None:
    query = query.decode(errors=‘replace‘)
return query
#改为
if query is not None:
    query = query.encode(errors=‘replace‘)
return query

OK~ 不再报错
