PHPunitが上手くいかない MAMP phalcon

Question

前提・実現したいこと

MAMPで動かしているアプリのPHPunitを実施したいがエラーが起きてしまいます。

導入は以下の公式のドキュメントを参考にしています。
composer.jsonの中身は、phpとphalcon(2系)のバージョンに対応する、バージョンを調べてupdatesしています。

おそらくMAMPで作成しているアプリはMAMPのPHP Version 5.6.37で動かしているのですが
macにはいっているPHP 7.4.6がターミナルで./vendor/bin/phpunit を実施した際に動いている気がします。

MAMPのPHPに向ける方法はありますでしょうか。

incubatorとphpunitインストール以外はドキュメント通りに進めています。
./vendor/bin/phpunitコマンドを入力した時のエラーです。
