我在 macos 安裝 mariadb 透過 brew

mysql.server start
Starting MariaDB
 SUCCESS! 

但我發現我的程式出現了錯誤
以下是完整錯誤

<b>Fatal error</b>: Uncaught Pimple\Exception\UnknownIdentifierException: Identifier "mysql" is not defined.
in /Users/xxx/Projects/abc/vendor/pimple/pimple/src/Pimple/Container.php:101
Stack trace:
#0 /Users/xxx/Projects/abc/public/meekro.php(3): Pimple\Container->offsetGet('mysql')
#1 /Users/xxx/Projects/abc/public/index.php(26): include_once('/Users/xxx/Proj...')
#2 {main}
thrown in <b>/Users/xxx/Projects/abc/vendor/pimple/pimple/src/Pimple/Container.php</b> on line <b>101</b><br />

實在是搞不清楚發生什麼事
有大大有遇過嗎？

補充
我執行了 mysql_secure_installation
發現會出現錯誤：

Enter current password for root (enter for none): 
/usr/local/bin/mysql_secure_installation: line 249: .my.cnf.55486: Permission denied
/usr/local/bin/mysql_secure_installation: line 250: .my.cnf.55486: Permission denied

/usr/local/bin/mysql_secure_installation: line 220: .mysql.55486: No such file or directory

但我是可以登入資料庫的

xxx @ etc $ mysql -u aaa -p
