mac + python3.8 + django3.0.8 + mysql 遇到数据库连接包问题

到达数据库迁移的时候， 出现了错误

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?

安装pymysql包

pip install pymysql

然后在与想settings.py 同一文件夹的_init_.py中增加

import pymysql

pymysql.install_as_MySQLdb()

增加完成了之后又出现了错误

File "/Users/mac/.virtualenvs/django-sPhxDNwQ/lib/python3.7/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.
　　　　

方案是去Django的包中改代码

路径是：

/Users/mac/.virtualenvs/django-sPhxDNwQ/lib/python3.7/site-packages/django/db/backends/mysql/base.py

我的是虚拟环境，个人找自己mysql的安装包文件base.py

把这行

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

改成这样, 全部注释：

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

然后在改另一个文件

路径是： /Users/mac/.virtualenvs/django-sPhxDNwQ/lib/python3.7/site-packages/django/db/backends/mysql/operations.py

把这行

query = query.decode(errors='replace')

改成

query = query.encode(errors='replace')
