我是laravel的新手，希望有人可以帮助我。
该项目现在有迁移和种子，我需要将它放在mySQL中。我按照官方网站的说明安装了laravel并进行了迁移过程。 .env文件也正确设置。但是，我不知道为什么我不能使用工匠。每当我尝试它时，它会说
[InvalidArgumentException]
Missing client credentials key [identifier] from options.
我曾尝试使用作曲家进行更新（这里提到https://laracasts.com/discuss/channels/forge/problems-installing-my-site-on-forge），但它没有用。
这是我运行更新或安装时的输出
yang$ php composer.phar install
Loading composer repositories with package information
