PHP致命错误：在第50行Laravel上调用index.php中的成员函数make（）

Question

I am getting below error :-

PHP Fatal error:  Call to a member function make() on string in /home/karaoke/web/example.com/public_html/index.php on line 50
PHP Stack trace:
PHP   1. {main}() /home/karaoke/web/example.com/public_html/index.php:0

My laravel public/index.php is as it was default.

Certain points :-

1. This site is working fine in localhost
2. But, same site is not working on server.

Things i have already done and tried :

1. Checked chmod of all file and folder. 2.. storage directory and directory/files is writable.
2. Cross checked index.php file already 10 time now and see no error.
3. files are perfectly readable in index.php file and no file is missing nor any file is missing to open.

I am running Centos 6.8 with php version 5.6. My Laravel version is 5.2

My index.php if some one needs them :-

<?php

/**

$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);

$response = $kernel->handle(
    $request = Illuminate\Http\Request::capture()
);

$response->send();

$kernel->terminate($request, $response);

Answer 1

The error indicates that the make() method on line 50

$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);

is not called on an object. Normally your $app variable would hold an instance of Illuminate\Foundation\Application. It does that via requireing __DIR__.'/../bootstrap/app.php';.

Please check if the file bootstrap/app.php is present and has the right content.
