nodejs连接mysql报错：Client does not support authentication protocol requested by server; consider upgrad

由于本人是前端，mysql只是偶尔做一下小项目会用到，大概一年没有用了。
今天用mac通过brew下载了一个8.0.12版本的mysql;然后用egg进行连接,egg是阿里封装的一个nodejs框架。
下载到本地的mysql；初始密码我是留空的。
所以在nodejs项目中配置mysql连接数据的时候我的password=’’；

结果报错了：

Client does not support authentication protocol requested by server; consider upgrad

我怀疑是MySQL密码的问题；于是我到网上找了很多种修改密码方法：

//开启mysql服务
mysql.server start
//进入mysql
mysql -u root -p
//修改密码方案1（错）
USE mysql SET PASSWORD FOR 'root'@'localhost' = OLD_PASSWORD('密码');
//修改密码方案2（错）
UPDATE mysql.user SET Password = OLD_PASSWORD('密码')WHERE Host = 'localhost' AND User = 'root';
//修改密码方案3（对）
USE mysql;
ALTER USER 'root'@'localhost'IDENTIFIED WITH mysql_native_password BY '密码';
//重启
FLUSH PRIVILEGES;

修改密码后的nodejs项目的配置文件

client: {// hosthost: 'localhost',// 端口号port: '3306',// 用户名user: 'root',// 密码password: '123456',// 数据库名database: 'blog',},

最后用了方案3终于连接上了；记住你运行nodejs项目时一定要先将mysql的服务打开，不然也是连不上的。
