我最近从在 Mac 上使用内置的 Apache2 和 PHP 安装切换到最新版本的 MAMP (3.5)，并将我的所有项目移动到 htdocs 文件夹中。更新到新的 MySQL 信息后，除了我的 Laravel 项目外，一切正常。当尝试访问任何使用 MySQL 的内容时，出现此错误

Connector.php 第 55 行中的 PDOException:SQLSTATE[HY000] [1045] 用户 'cumc'@'localhost' 的访问被拒绝(使用密码:YES)

新的 .env 文件在数据库信息中看起来是这样的。

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=cumc
DB_USERNAME=root
DB_PASSWORD=root

所以根据错误，看起来有些东西被缓存了，但我已经运行了我能找到的每一个 cache:clear 命令，重新启动 MAMP，我的 Mac，并尝试了我能想到的一切。即使用新的细节更改 app/database.php，并更改 .env 的名称，这样它就不会加载，它仍然显示错误。

这是 config/database.php 文件

最佳答案

运行php artisan config:clear，它将清除缓存的配置。
