在 Google 云上部署 Symfony 4.2

Question

我正在尝试在 Google 云上部署 Symfony 4.2。使用本教程： https://cloud.google.com/community/tutorials/run-symfony-on-appengine-flexible

它部署没有错误，但是当我尝试访问时它给了我 500。来自 Google 的日志：

我尝试了其他安装演示 symfony 应用程序的现有教程，这不是我想要的，但它几乎可以工作，除了它不加载 CSS 和 JS。 https://cloud.google.com/community/tutorials/run-symfony-on-appengine-standard

任何关于如何调试它的想法都会有所帮助。

编辑：

在开发模式下部署后出现此错误：

(1/1) ClassNotFoundException
Attempted to load class "WebProfilerBundle" from namespace "Symfony\Bundle\WebProfilerBundle".
Did you forget a "use" statement for another namespace?

in Kernel.php line 23
at Kernel->registerBundles()
in Kernel.php line 424
at Kernel->initializeBundles()
in Kernel.php line 130
at Kernel->boot()
in Kernel.php line 193
at Kernel->handle(object(Request))
in index.php line 25

Answer 1

ClassNotfoundException 表示 config/bundle 中未找到 WebProfilerBundle class。[=19= 中不存在 php ]。由于 Symfony 4.1 => 4.2 的更新，我运行同样的问题。在部署之前，您必须使用 composer update 和 composer upgrade 命令正确更新您的 symfony 项目。如有必要，请检查 composer.json

中的限制列表

Answer 2

帮助找出项目问题的最大帮手是添加：

APP_DEBUG: 1

允许开始显示错误消息。
