Laravel 5：数据库迁移（帮助！）

Question

一些有用的信息：

• 我在OS X（El Capitan Beta）上运行
• 我正在使用XAMPP
• 我已经成功安装了Laravel 5，并且可以确认它能正常工作。

这是我的迁移文件：

<?php

use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateUsersTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('users', function(Blueprint $table) {
            $table->increments('id');
            $table->string('email');
            $table->string('username');
            $table->string('password');
            $table->string('first_name')->nullable();
            $table->string('last_name')->nullable();
            $table->string('remember_token')->nullable();
            $table->timestamps();
        });
    }

/**
 * Reverse the migrations.
 *
 * @return void
 */
public function down()
{
    Schema::drop('users');
}
}

我的.env文件

APP_ENV=local
APP_DEBUG=true
APP_KEY=TvzwP6TLLRWK4zXDGDeudPOZnvXxYENz

DB_HOST=localhost
DB_DATABASE=users
DB_USERNAME=root

SESSION_DRIVER=file
QUEUE_DRIVER=sync

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null

我的database.php文件

<?php

当我在终端上运行“ php artisan migration”时，

  [PDOException]                                    
  SQLSTATE[HY000] [2002] No such file or directory

我的数据库连接凭据是：主机是：'localhost'db用户名是：'root'db密码是：''

我的数据库中没有表，我想运行迁移来创建表。

提前致谢

Answer 1

当您连接到localhost时 ，PDO尝试使用不存在的UNIX套接字文件连接到数据库。 将localhost替换为127.0.0.1 ，它将使用TCP连接连接到您的数据库，这应该可以解决此问题。
