php - 全新安装的 laravel 5.6 在索引页面中获取 HTTP ERROR 500

Question

大家好，我很难调试从 php 7.0 升级到 php 7.1 后新安装的 laravel 5.6 中的问题。我已经为我的测试项目生成了一个应用程序 key 。将所有者更改为 www-data 并将权限更改为 777，因为它只是一个测试项目。

重启 php 7.1 fpm 和 NGINX 也完成了。

请注意，我可以在运行 php aritsan serve 命令后运行项目，我也可以 ping 项目但无法使用 laraveltestauth.ng 访问它 在 URL 中。

laravel.log

php artisan server 运行正确的 CLI 版本和最新的 7.1。

您的网络服务器仍在运行旧的 PHP 版本。确保使用最新版本正确设置。即使您删除了旧版本，您的服务器仍然可以在内存中继续运行，直到问题得到解决。

尝试service php7.0-fpm stop和service php7.1-fpm restart和service nginx restart。
