将Ruby rails连接到MySQL数据库

我希望这个问题不是多余的。我看到了一个几乎与之相似的问题，但由于问题有点不同，因此没有任何帮助

当使用

sudorakedb:migrate

时，我试图将我的ruby-rails应用程序连接到MySQL数据库，但是（和一些其他命令）我得到了以下输出

错误显示我设置了密码，但据我所知，我没有设置。我已经采取了我所能想到的一切措施，以确保没有任何一套

任何帮助都将不胜感激。

错误的（使用密码：是）部分表示您发送了密码进行身份验证，而不是设置了密码。如果数据库中没有设置密码，请从database.yml中删除

password:which

行。

错误的（使用密码：YES）部分表示您发送了密码进行身份验证，而不是设置了密码。如果数据库中没有设置密码，请删除数据库中的

password:which

行。yml。

错误表示您发送了一个密码进行身份验证，但没有设置密码。这是一大堆问题的骗局。密码是从database.yml文件以外的其他地方获取的吗？是的。去掉你的密码行，你没有密码。我已经把它修好了。感谢此错误表示您发送了一个密码进行身份验证，而不是设置了密码。这是一大堆问题的骗局。密码是从database.yml文件以外的其他地方获取的吗？是的。去掉你的密码行，你没有密码。我已经把它修好了。谢谢
