Python 当我执行syncdb时，UnicodeDecodeError与Django

我试图用MySQL设置Django，但出现了UnicodeDecodeError。 你能告诉我怎么解决这个问题吗？我查了一下错误，但不明白

我找到了那些密码并试过了

def __unicode__(self):
    return str(self.id) + ':' + self.name

及

但我无法解决这个问题，可能是因为我不知道如何使用defunicode（），而且这些不适合我的列

以下是命令

我在使用centOS6时没有出现这种错误，尽管这些软件的版本不同。 如果您能为我提供一些解决方案或建议，我们将不胜感激。 谢谢

另外，我是这个网站的新手，所以我不知道如何在这里正确提问。很抱歉。

问题似乎与回溯无关；在“数据库”之前只需要两个破折号。嗨，丹尼尔。谢谢你的回复。对不起，我写错了。我使用“-database mydj”执行，但仍然有UnicodeDecodeError。谢谢，我可以解决这个问题。我在Linux中使用了Django的旧版本，并且已经习惯了，更糟糕的是我们只有1.4版本的日语文档。所以，我不知道我们不应该再使用syncdb了。我改用了迁移，问题似乎与回溯无关；在“数据库”之前只需要两个破折号。嗨，丹尼尔。谢谢你的回复。对不起，我写错了。我使用“-database mydj”执行，但仍然有UnicodeDecodeError。谢谢，我可以解决这个问题。我在Linux中使用了Django的旧版本，并且已经习惯了，更糟糕的是我们只有1.4版本的日语文档。所以，我不知道我们不应该再使用syncdb了。我用迁移代替。
