Django2.2 problem solving MySQL connection

A error:

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

Workaround: Edit the file, comment out the following line:

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

 

Error two:

File "D:\data\gitee.com\ExamOnline\venv\lib\site-packages\django\db\backends\mysql\operations.py", line 146, in last_executed_query query = query.decode(errors='replace') AttributeError: 'str' object has no attribute 'decode'

Solution:

Edit the file operations.py, comment out the following line

query = getattr(cursor, '_executed', None)
# if query is not None:
# query = query.decode(errors='replace')
return query
