php - 为尝试转换传递的无效字符，这些已被忽略 - 将 Laravel 项目推送到 heroku

问题描述

我正在尝试从服务器获取一个 laravel 项目并按照所有提供的步骤将其移动到 heroku，当将 repo 推送到 heroku 时，我遇到以下错误：

 Compiling common classes
remote:        
remote:
remote:          [ErrorException]
remote:          Invalid characters passed for attempted conversion, these have been ignored

我一直在查看一个说明此错误的 Guthub 问题 - [PHP 7.4 RC3] 为尝试转换传递的无效字符，这些已被忽略 #2003 - 这是我能找到的少数答案之一。但是，我的项目（vendor/dompdf/dompdf/lib/Cpdf.php）中不存在此问题引用的文件。

error_reporting(E_ALL ^ E_DEPRECATED);其中一个答案建议通过添加到引发错误的文件来关闭错误报告。知道把那条线放在哪里吗？

我看不到错误被抛出的文件。见消息：

      Script php artisan optimize handling the post-install-cmd event returned with error code 1
remote:  !     WARNING: A post-install-cmd script terminated with an error
remote:
remote:  !     ERROR: Dependency installation failed!

我可能正在做一些明显错误的事情。按照以下步骤进行迁移：在 Heroku 上部署 Laravel 项目

编辑：也按照这个问题printing-preview-doesnt-working-laravel-dompdfcomposer update的回答中的建议进行了尝试

编辑2：下面是构建日志：

我试过更新mtdowling/cron-expression包 - 但它一直在恢复它。这或 Carbon 错误是否会导致“无效字符错误”？

解决方案

升级dompdf/dompdf到版本0.8.5将解决这个问题：https ://github.com/dompdf/dompdf/releases

可以通过以下方式安装最新版本：

composer require dompdf/dompdf

或composer.json手动修改0.8.5并运行：

composer install

请记住，此升级可能包含重大更改
