Symfony 抛出 "Make sure there is a loader supporting the "/config/config_dev.yml“类型”错误?

Symfony is throwing a "Make sure there is a loader supporting the "/config/config_dev.yml" type" error?

我有一个一年前在 Symfony 3.4 中构建的应用程序,我需要再次短暂地使用它但是,当我检查它并尝试 运行 它时,我得到了错误:

Cannot load resouce "<folder_path_here>". Make sure there is a loader supporting the "/config/config_dev.yml" type

我以前没有遇到过这种情况,并且已经查找了有关可能导致这种情况的任何信息,但我仍然 none 比较聪明。

我的config_dev.yml文件供参考:

imports:
  - { resource: config.yml }

monolog:
  handlers:
    main:
      type: stream
      path: "%kernel.logs_dir%/%kernel.environment%.log"
      level: info
    console:
      type: console
      bubble: false

还有我的AppKernel.php

<?php

use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = [
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\MonologBundle\MonologBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Symfony\Bundle\SecurityBundle\SecurityBundle(),
            new Checkout\Checkout()
        ];

        if (in_array($this->getEnvironment(), ['dev', 'test'], true)) {
            $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
        }

        return $bundles;
    }

    public function getRootDir()
    {
        return __DIR__;
    }

    public function getCacheDir()
    {
        return dirname(__DIR__) . '/var/cache/' . $this->getEnvironment();
    }

    public function getLogDir()
    {
        return dirname(__DIR__) . '/var/logs';
    }

    public function registerContainerConfiguration(LoaderInterface $loader)
    {
        $loader->load(__DIR__, '/config/config_' . $this->getEnvironment() . '.yml');
    }
}

别理我。我是个白痴。 registerContainerConfiguration 中有错字。一个“,”而不是一个“。” ._.
