但是它抛出了这个错误：

i have required it in start.php

我在 start.php 中需要它

<?php
require 'database.php';
//############ NAMESPACING ################//
use Slim\Slim; //import slim
use Noodlehaus\Config;
use Boilerplate\User\User;
//#########################################//

session_cache_limiter(false);
session_start();

ini_set('display_errors','on'); //TURN OFF ON LIVE SITE

define('INC_ROOT', dirname(__DIR__)); //create local root

require INC_ROOT . '/vendor/autoload.php'; // autoload in all the      dependencies in the vendor files.

$app = new Slim([
'mode' => file_get_contents(INC_ROOT . '/mode.php')
]); //assign the entire app file to a variable

$app->configureMode($app->config('mode'), function() use ($app){
$app->config = Config::load(INC_ROOT . "/app/config/{$app->mode}.php"); //pull in the config file
});

$app->container->set('user', function(){
    return new User;
});

Make sure you've added Illuminate\Databaseto you're composer file and run composer update

确保你已经添加Illuminate\Database到你的作曲家文件并运行composer update

Then put require 'database.php';after you're adding the autoloader

然后require 'database.php';在添加自动加载器之后放置

require INC_ROOT . '/vendor/autoload.php';

I had the same error. In my case the solution was to install composer again with the next command:

我有同样的错误。在我的情况下，解决方案是使用下一个命令再次安装 composer：

composer install

If you are using docker, make sure that you are inside the container before run the install command.

如果您使用的是 docker，请确保您在运行安装命令之前位于容器内。

docker-compose run <app_name> bash
