创建 Symfony 4 项目时出现致命错误

Question

运行后

     composer create-project symfony/website-skeleton my-project

我收到一个错误：

Executing script cache:clear [KO]
 [KO]
Script cache:clear returned with error code 255
!!  
!!  Fatal error: Uncaught SymfonyComponentDebugExceptionClassNotFoundException: Attempted to load class "FileResource" from namespace "App".
!!  Did you forget a "use" statement for "SymfonyComponentConfigResourceFileResource"? in /Users/bastiennicolau/Documents/dev_web/my-project/src/Kernel.php:39
!!  Stack trace:

!!  

我已经尝试了一些事情，例如更改 composer.json 中的 psr-4 值，并且在运行 cache:clear 后仍然有相同的错误......

你会怎么做才能让它工作？谢谢。

您可以尝试通过打开 src/kernel 来解决此问题.php然后转到第 39 行。

删除"文件资源"，然后再次开始键入。您的IDE(假设PHPStorm(将建议您使用来自以下位置的FileResource：Symfony\Component\Config\Resource\FileResource;

这应该自动添加到内核.php的顶部。

接受并运行作曲家更新。该问题应得到解决。
