Php 找不到驱动程序Yii2迁移

我是Yii2新手，因此在迁移到XAMPP服务器时遇到问题。我的PHP版本是7.1.11。我正在使用Yii2高级模板，这就是我的

common/config/main local.php

文件的样子

<?php
return [
    'components' => [
        'db' => [
            'class' => 'yii\db\Connection',
            'dsn' => 'mysql:host=127.0.0.1;dbname=hopordrop',
            'username' => 'root',
            'password' => '',
            'charset' => 'utf8',
        ],
        'mailer' => [
            'class' => 'yii\swiftmailer\Mailer',
            'viewPath' => '@common/mail',
            // send all mails to a file by default. You have to set
            // 'useFileTransport' to false and configure a transport
            // for the mailer to send real emails.
            'useFileTransport' => true,
        ],
    ],
];

运行

php-m

命令时：

正如您在上看到的，您需要安装pdo，在您的情况下，pdo_mysql。您缺少最后一个。

尝试在web或控制台中运行

requirements.php

文件，检查您的DB相关PDO是否为绿色。如果没有，那么XAMPP配置可能有问题。请尝试在web或控制台中运行
