mysql - reading initial communication packet - password hash should be a 41-digit hexadecimal number

现象：在苹果电脑上的xampp，访问phpmyadmin时提示错误，错误信息如：reading initial communication packet password hash should be a 41-digit hexadecimal number。

尝试：在my.cnf文件里添加 skip-grant-tables 后重启mysql，再登录到mysql，通过 UPDATE user SET Password = PASSWORD('newpwd') WHERE Host = 'localhost' AND User = 'root'; 来重置root用户的密码。
