创建 Symfony 4 项目时出现致命错误

Fatal error while creating Symfony 4 project

在运行

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

我收到一个错误:

Executing script cache:clear [KO]

我尝试了一些方法,例如更改 composer.json 中的 psr-4 值,但在 运行 cache:clear...[=15 之后仍然出现相同的错误=]

你会怎么做才能让它发挥作用?谢谢。

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。

删除"FileResource",然后重新开始输入。您的 IDE(假设是 PHPStorm)将建议您使用 FileResource 来自:Symfony\Component\Config\Resource\FileResource;

这应该会自动添加到 Kernel.php 的顶部。

接受并 运行 作曲家更新。该问题应得到解决。
