    使用Django框架创建完models类的之后,用python manage.py migrate命令来生成数据库表的时候出错

    错误代码

    复制代码
    Operations to perform:
      Apply all migrations: SMS, admin, auth, contenttypes, sessions

        self._out.write(force_str(style_func(msg)))
    OSError: raw write() returned invalid length 42 (should have been between 0 and 21)
    复制代码

    错误原因

    与win10系统、版本有关系

    可能是unicode字符的返回值问题

    解决办法

    可以使用pip install win_unicode_console安装win_unicode_console,在代码文件中添加以下两行代码解决:

    1
    2
    import win_unicode_console
    win_unicode_console.enable()
