解决方案

这是相关的错误消息：

唯一受支持的密码是具有正确密钥长度的 AES-128-CBC 和 AES-256-CBC。在 /app/vendor/laravel/framework/src/Illuminate/Encryption/Encrypter.php:43

看起来你的APP_KEY设置不正确。

在开发中，这可能会通过您的.env文件设置，该文件不应包含在您的存储库中。该文件只是开发中设置环境变量的一种便捷方式；Heroku通过 config vars 原生支持环境变量。

要么生成一个新文件，要么APP_KEY从你的文件中复制一个.env文件，然后通过运行在 Heroku 上设置它

heroku config:set APP_KEY=<your_key>

或通过门户网站。
