无法在 Windows 上重新安装 MySql "Could not connect to MySql with the given password"。忘记根密码

Question

我正在学习Spring批处理。我按照说明安装 MySQL Shell 8.0.26 以及 Workbench 8.0 on Windows 11.

不过我得到

MySQL  JS > alter user 'root'@'localhost' IDENTIFIED WITH mysql_native_password by 'password';
SyntaxError: Unexpected identifier
 MySQL  JS > show schemas;
SyntaxError: Unexpected identifier
 MySQL  JS > show databases;

所以我尝试卸载并重新安装 MySql。当我运行安装程序时，

我忘记了root密码。我该怎么办？

在此 similar SO 问题中，此人记住了密码。

我进行了互联网搜索并尝试按照此处的步骤进行操作

我找到这篇文章，它说必须手动删除以下文件夹。仅从 Windows 控制面板卸载是不够的。

C:\Program Files\MySQL

C:\Program Files (x86)\MySQL

C:\ProgramData\MySQL

我按照步骤操作，当我再次运行安装程序时，它要求输入新的 root 密码！
