1.使用Python3.7 + Django2.2 + MySQL 5.5 在执行(python manage.py migrate)命令时出现错误django.db.migrations.exceptions.MigrationSchemaMissing

原因是

 所以,需要重新安装高版本的sql,安装好之后,问题就解决了

 

 

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
