Fzaninotto Faker安裝包

Question

你能幫我解決laravel中的這個錯誤嗎？我跑php artisan db:seed --class=UserTableSeeder，並得到：

PHP致命錯誤：

Class 'Faker\Factory' not found in /Users/I/Laravel/authapp/app/database/seeds /UserTableSeeder.php on line 7

{ 
"error":{ 
    "type":"Symfony\\Component\\Debug\\Exception \\FatalErrorException", 
    "message":"Class 'Faker\\Factory' not found", 
    "file":"\/Users /I\/Laravel\/authapp\/app\/database\/seeds\/UserTableSeeder.php", 
    "line":7 
} 
} 

我UserTableSeeder.php

<?php 
class UserTableSeeder extends Seeder 
{ 

    public function run() 
    { 

     $faker = Faker\Factory::create(); 

     User::truncate(); 

     foreach(range(1,30) as $index) 
     { 
      User::create([ 
       'username' => str_replace('.', '_', $faker->unique()->userName), 
       'email' => $faker->email, 
       'password' => 'password', 
      ]); 
     } 
    } 
} 

我composer.json

{ 
    "name": "laravel/laravel", 
    "description": "The Laravel Framework.", 
    "keywords": ["framework", "laravel"], 
    "license": "MIT", 
    "require": { 
     "laravel/framework": "4.2.*", 
     "fzaninotto/faker": "1.3.*@dev" 
    }, 
    "autoload": { 
     "classmap": [ 
      "app/commands", 
      "app/controllers", 
      "app/models", 
      "app/database/migrations", 
      "app/database/seeds", 
      "app/tests/TestCase.php" 
     ] 
    }, 
    "scripts": { 
     "post-install-cmd": [ 
      "php artisan clear-compiled", 
      "php artisan optimize" 
     ], 
     "post-update-cmd": [ 
      "php artisan clear-compiled", 
      "php artisan optimize" 
     ], 
     "post-create-project-cmd": [ 
      "php artisan key:generate" 
     ] 
    }, 
    "config": { 
     "preferred-install": "dist" 
    }, 
    "minimum-stability": "stable", 
    "require-dev": { 
    "fzaninotto/faker": "1.3.*@dev" 
    }, 

} 

添加逗號後，我仍然得到相同的錯誤，如果我嘗試使用自動加載從github包括它也不起作用。我在哪裏可以查找錯誤？

我仍然得到相同的錯誤。我很害怕它沒有加載Fzniotto Faker軟件包。我能做什麼？如果我嘗試downlaoding它包括包，我得到

Answer 1

我仍然得到同樣的錯誤。我很害怕它沒有加載Fzniotto Faker軟件包。我能做什麼？

在您的shell中，嘗試運行php artisan dump-autoload。

---

運行composer update，然而你卻在你的composer.json中缺少一個逗號;

"require": { 
    "laravel/framework": "4.2.*" 
    "fzaninotto/faker": "1.3.*@dev" 
} 

應該是;

"require": { 
    "laravel/framework": "4.2.*", 
    "fzaninotto/faker": "1.3.*@dev" 
} 

如果您已經有了依賴關係並且錯誤地複製了代碼，請嘗試運行composer dump-autoload。

Answer 2

是啊，你忘了一個逗號

"require": { 
    "laravel/framework": "4.2.*", 
    "fzaninotto/faker": "1.3.*@dev" 
}, 

然後運行composer update

Answer 3

不過，我現在不再得到一個錯誤，但我也不會在我的表中獲取任何用戶。這似乎根本不起作用，例如。該表不是創建並填充lorem ipsum用戶。我能做什麼？

您是否創建了用戶表？

如果不是，你需要;

運行php artisan migrate:make create_users_table。

在您的app/database/migrations文件夾中，您將找到新的遷移文件。

構建您的遷移（http://laravel.com/docs/4.2/schema）。

運行php artisan migrate。

運行php artisan db:seed。
