MySQL Workbench：从 SQL 任何地方迁移到 MySQL 时出现类型错误

Question

我正在尝试将一些数据从 SQL Anywhere 16 数据库迁移到 MySQL 以将数据转换为可用格式。我正在关注 this tutorial

在迁移过程中遇到以下错误。 Reverse engineer selected schemas 失败并显示以下日志消息：

Starting...    
Connect to source DBMS...    
- Connecting...    
Connect to source DBMS done    
Reverse engineer selected schemas....

    SystemError: TypeError("serverVersion() takes exactly 2 arguments (1 given)"): error calling Python module function DbSQLAnywhereRE.reverseEngineer    
ERROR: Reverse engineer selected schemas: TypeError("serverVersion() takes exactly 2 arguments (1 given)"): error calling Python module function DbSQLAnywhereRE.reverseEngineer

这似乎是 Python 模块本身的错误，所以我完全不知道如何修复它。

您确实发现了迁移向导中的错误。请在 http://bugs.mysql.com 处填写错误报告。同时，您可以通过在文本编辑器中打开文件 C:\Program Files\MySQL\MySQL Workbench 6.3 CE\modules\db_sqlanywhere_re_grt.py 来解决此问题，转到第 192 行并更改行：
如果 cls.serverVersion().majorNumber < 12:
至
如果 cls.serverVersion(连接).majorNumber < 12:
然后再次保存文件和运行迁移向导。编辑时要小心，这是 python 文件，所以每个 space 的标识都有问题。
