【问题描述】：

我最近将项目中的 Laravel 从 5.8.* 升级到了 6.x 版本。

现在，当我尝试运行命令 composer dump-autoload -o 时，我收到此错误：

Declaration of App\Exceptions\Handler::renderHttpException(Symfony\Component\HttpKernel\Exception\HttpException $e)
   should be compatible with Illuminate\Foundation\Exceptions\Handler::renderHttpException(Symfony\Component\HttpKern
  el\Exception\HttpExceptionInterface $e)

下面是项目中设置的composer.json，当我将 Laravel 从 5.7.* 升级到 5.8.* 时，我也遇到了与上述相同的错误，但我进一步升级希望能解决问题：

我已经参考了文档，但没有具体说明任何 Exception 或 Handler.php 文件更改，所以任何人都建议如何解决这个问题...

【解决方案1】：

这是一个 5.7 到 5.8 的升级问题，正如您在问题开始时指出的那样。该方法的签名已更改：

“Illuminate\Foundation\Exceptions\Handler 类的 renderHttpException 方法签名已更改。如果您在异常处理程序中重写此方法，则应更新方法签名以匹配其父级：”

/**
 * Render the given HttpException.
 *
 * @param  \Symfony\Component\HttpKernel\Exception\HttpExceptionInterface  $e
 * @return \Symfony\Component\HttpFoundation\Response
 */
protected function renderHttpException(HttpExceptionInterface $e);
