Laravel 5.8 到 6.x 升级错误 - App\Exceptions\Handler::renderHttpException 声明

Question

我最近将项目中的 Laravel 从 5.8.* 升级到 6.x 版本。

现在，当我尝试运行命令 composer dump-autoload -o 时，出现此错误：

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，也出现了和上面一样的错误，但我希望进一步升级这将解决问题：

我已经参考了文档，它没有具体说明任何 Exception 或 Handler.php 文件更改，所以有人建议如何解决这个...

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：

"The renderHttpException method signature of the Illuminate\Foundation\Exceptions\Handler class has changed. If you are overriding this method in your exception handler, you should update the method signature to match its parent:"

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