php - SQLiteConnector.php 第 34 行中的 InvalidArgumentException : Database (homestead) does not exist

Question

我在 Laracasts 中从头开始关注 Laravel 5 系列，具体来说，我正在学习“获取数据”类(class)。

我创建了 database.sqlite 文件，我从修补程序中添加了一些数据，并且能够在控制台中检索它们。然后，我尝试复制视频的功能。

我的卡片 Controller :

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;

use App\Http\Requests;

class CardsController extends Controller
{
    public function index()
    {
        $cards = \DB::table('cards')->get();
        return view('cards.index', compact('cards'));
    }
}

但是，当我尝试加载/cards 路由时，出现以下错误

InvalidArgumentException in SQLiteConnector.php line 34:
Database (homestead) does not exist.

这是我的 env文件

APP_ENV=local
APP_DEBUG=true
APP_KEY=base64:P3ZgRMRkb2e8+x7S9rDLLB+bKJdR5Unpj8zXBUIHIZE=
APP_URL=http://localhost

DB_CONNECTION=sqlite
DB_FILE=database.sqlite


CACHE_DRIVER=file
SESSION_DRIVER=file
QUEUE_DRIVER=sync

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

MAIL_DRIVER=smtp

Answer 1

在您的错误中引用的那一行下，是以下内容:

    // Here we'll verify that the SQLite database exists before going any further
    // as the developer probably wants to know if the database exists and this
    // SQLite driver will not throw any exception if it does not by default.
    if ($path === false) {
        throw new InvalidArgumentException("Database (${config['database']}) does not exist.");
    }

查看方法上面的注释，似乎您的路径设置不正确。我相信正确的环境变量应该是:
DB_DATABASE=database/database.sqlite
代替
DB_FILE=database/database.sqlite
如果没有，请检查您的 config/database.php文件，然后查找此部分:

    'sqlite' => [
        'driver' => 'sqlite',
        'database' => env('DB_DATABASE', database_path('database.sqlite')), // this line!
        'prefix' => '',
    ],
