Answer 1

错误已经非常明显了，你下载的代码需要连接mysql数据库，所以在她的代码某一段关于数据库的那几行应该有配置mysql的用户名和密码的，你改成自己本地的即可。

Answer 2

Access denied for user 'root'@'localhost' (using password: YES)

很明显是密码错误，查查代码里的配置文件，把用户名密码改成你的环境的真实值

Answer 3

你看配置文件里mysql的用户名密码对吗

Answer 4

权限问题，应该是数据库配置有问题。查看一下密码

追问

数据库配置没有问题，用户名密码都已经检查过了，没问题

Answer 5

这不是已经提示你拒绝登陆了吗，检查你的用户名和密码
