创建Symfony 4项目时出现致命错误 [英] Fatal error while creating Symfony 4 project

问题描述

运行后

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

我得到一个错误：

Executing script cache:clear [KO]
 [KO]
Script cache:clear returned with error code 255
!!  
!!  Fatal error: Uncaught Symfony\Component\Debug\Exception\ClassNotFoundException: Attempted to load class "FileResource" from namespace "App".

我尝试了一些更改 psr-4 composer.json 中的c $ c>值，并且在运行 cache：clear 后仍然出现相同的错误...

I've tried some things like changing the psr-4 value in composer.json, and still having the same error after running cache:clear...

您将如何使其工作？谢谢。

What would you do to make it work ? Thanks.

推荐答案

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

You can try to fix this by opening src/Kernel.php and then go to line 39.

删除 FileResource，然后再次开始输入。您的IDE（假设PHPStorm）将建议您从以下位置使用FileResource：Symfony\组件\Config\Resource\FileResource；

Delete "FileResource" and then start typing it again. Your IDE (assuming PHPStorm) will suggest that you use FileResource from: Symfony\Component\Config\Resource\FileResource;

这应该自动添加到Kernel.php的顶部。

This should be automatically added in the top of Kernel.php.

接受并运行作曲家更新。该问题应得到解决。

Accept that and run composer update. The issue should be resolved.

最好，
