2.Django数据同步过程中遇到的问题:
1)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.
解决办法:C:\\Python37\\Lib\\site-packages\\django\\db\\backends\\mysql(python安装目录)打开base.py,注释掉以下内容:
if version < (1, 3, 13):
raise ImproperlyConfigured(\'mysqlclient 1.3.13 or newer is required; you have %s.\' % Database.__version__)
2) File "C:\\Python37\\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\'
解决办法:打开此文件把146行的decode修改为encode
