Fzaninotto Faker 安装包

Question

你能帮我解决 laravel 中的这个错误吗？我跑了php artisan db:seed --class=UserTableSeeder 并得到：

PHP 致命错误：

在 /Users/I/Laravel/authapp/app/database/seeds 中找不到类 'Faker\Factory' /UserTableSeeder.php 第 7 行

{
"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
}
}

我的 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', 
            ]);  
        }
    }
}  

我的 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"
  },

}

添加逗号后，我仍然收到相同的错误，如果我尝试使用来自 github 的自动加载来包含它，它也不起作用。我在哪里可以找到错误？

我仍然遇到同样的错误。我害怕它没有加载 Fzniotto Faker 包。我能做些什么？如果我尝试通过下载包来包含它，我会得到 ​​p>

Answer 1

是的，你忘了一个逗号

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

然后运行composer update

Answer 2

我仍然遇到同样的错误。我害怕它没有加载 Fzniotto Faker 包。我能做什么？

在你的 shell 中，尝试运行php artisan dump-autoload。

---

运行 composer update，但是您的 composer.json 中缺少一个逗号；

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

应该是；

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

如果你已经有依赖并且复制错误的代码尝试运行composer dump-autoload。

Answer 3

但是，我现在不再收到错误消息，但我的表中也没有任何用户。它似乎根本不起作用，例如。该表未创建并填充 lorem ipsum 用户。我能做什么？

您是否创建了用户表？

如果没有，你需要；

运行php artisan migrate:make create_users_table。

在您的 app/database/migrations 文件夹中，您将找到新的迁移文件。

构建您的迁移 (http://laravel.com/docs/4.2/schema)。

运行php artisan migrate。

运行php artisan db:seed。
