服务器使用MultiHP Manager，因此为了使用php版本7.1，我必须使用所选的php版本（/opt/cpanel/ea-php71/root/usr/bin/php）

我的web服务器使用我的旧php版本5。要解决此问题，请尝试

sudo a2dismod php5 sudo a2enmod php7.0

---

sudo service apache2 restart

解决方案是与我的主机提供商联系，将PHP版本更改为>=5.6.4。

您的index.PHP文件有问题

require __DIR__.'/../bootstrap/autoload.php';

在这一行中，您必须用vendor替换此引导，因为laravel 5.6将自动加载文件存储在vendor文件夹中，而不是bootstrap文件夹中

---

请删除引导程序并添加供应商，然后运行

composer dump autoload命令

，然后尝试访问：）

您可以向我们展示index.php文件的内容并告诉我们您是如何进行新安装的吗？@JoffreyCarle updated检查您的php版本，因为在$kernel=$app->make（light\Contracts\Http\kernel:：class）行中；：：类方法无法解析，我认为您的php版本>5。1@VaheGalstyan通过命令

opt/cpanel/ea-php71/root/user/bin/php-v

返回PHP7.1.5，您可以在index.php文件的第一行添加var_dump（phpversion（））；die；，并显示结果

require __DIR__.'/../bootstrap/autoload.php';
