当我在app_dev.php上启用调试时，它会抛出500错误 这是我的app_dev.php
use Symfony\Component\HttpFoundation\Request;
$loader = require_once __DIR__.'/../app/bootstrap.php.cache';
require_once __DIR__.'/../app/AppKernel.php';
$kernel = new AppKernel('dev', true);
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);
我真的不知道在哪里看，我清除了prod和dev缓存。
这是我尝试从开发环境访问我的域后的dev.log报告：

答案 0 :(得分：0)
只有在使用Linux时才会出现此问题。 这与文件的权限有关。我没有跟踪确切的文件以更改权限，因为我急于完成项目。所以，我只是将Web根目录的内容更改为777，问题就解决了。
运行＆＃34; sudo chmod -R 777 *＆＃34;在你的/ var / www / html /＆＃34; home_directory＆＃34;中。这将解决您的问题。 但是现在你知道它是因为权限，所以请跟踪确切的文件以获得适当的权限;因为这个命令会将所有代码暴露给互联网。
