但是当我在public/index.php die('Working!') ，它将返回正在Working! 。 但是，当我删除该die时，Laravel会返回该错误！

我正在使用

PHP 7.2.14 Laravel Framework 5.7.27

我该如何解决？

Answer 1

如评论中所述，查找问题的关键在于以下通知：

date_default_timezone_set(): Timezone ID 'Asia/Tehran' is invalid

这与日志下方的致命错误有关：

DateTime::createFromFormat(): Timezone database is corrupt - this should *never* happen!.

强调时区数据库已损坏 。 Laravel完全失败的原因是因为它试图创建与响应一起的时间戳（可能是针对初始date_default_timezone_set通知的堆栈跟踪）。 进而导致致命错误。 您可以在致命错误上方的堆栈跟踪中看到此内容：

PHP message: PHP  55. Illuminate\\Http\\Response->__construct() /vendor/laravel/framework/src/Illuminate/Routing/Router.php:750
PHP message: PHP  56. Symfony\\Component\\HttpFoundation\\ResponseHeaderBag->__construct() /vendor/symfony/http-foundation/Response.php:201
PHP message: PHP  57. Symfony\\Component\\HttpFoundation\\ResponseHeaderBag->initDate() /vendor/symfony/http-foundation/ResponseHeaderBag.php:41
PHP message: PHP  58. DateTime::createFromFormat() /vendor/symfony/http-foundation/ResponseHeaderBag.php:295

要解决您的问题，您应该弄清楚为什么 PHP无法与时区数据库一起工作。 可能有两个原因，但有关更多信息，您可以检查此问题 ，其中包含一些答案。
