Symfony3.4 / Doctrine迁移 - 驱动程序中发生异常：SQLSTATE [HY000] [2002]没有这样的文件或目录

Question

我正在尝试在Symfony3.4项目中运行Doctrine迁移，但是我现在已经停留了几天。有人遇到过同样的问题吗？如何使这项工作？提前致谢！

php bin/console doctrine:migrations:migrate Version20180909015642

19:03:19 ERROR     [console] Error thrown while running command

"doctrine:migrations:migrate","message" => "An exception occured in 
driver: SQLSTATE[HY000] [2002] No such file or directory"] []

In AbstractMySQLDriver.php line 103:

Bundle在AppKernel.php中注册

new Doctrine\Bundle\MigrationsBundle\DoctrineMigrationsBundle(),

在config.yml中

doctrine_migrations:
    dir_name: "%kernel.root_dir%/DoctrineMigrations"
    namespace: Application\Migrations
    table_name: doctrine_migration_versions
    name: Application_Migrations_Default

应用程序/ DoctrineMigrations / Version20180909015642.php

<?php
declare(strict_types=1);

namespace Application\Migrations;

use Doctrine\DBAL\Migrations\AbstractMigration;
use Doctrine\DBAL\Schema\Schema;

/**
 * Auto-generated Migration: Please modify to your needs!
 */
class Version20180909015642 extends AbstractMigration
{


    /**
     * @param Schema $schema
     */
    public function up(Schema $schema)
    {
        //...
    }

    /**
     * @param Schema $schema
     */
    public function down(Schema $schema)
    {
        //...
    }
}

控制台命令有帮助选项-h非常有用。

 php bin/console doctrine:migrations -h

已经说过，要迁移到特定的迁移文件，您应该使用最终迁移文件的时间戳，如下所述

 php bin/console doctrine:migrations:migrate 20180909015642

但是，为了执行特定的迁移文件，应该使用execute命令;喜欢以下

php bin/console doctrine:migrations:execute 20180909015642 --up

获取有关特定命令的帮助以查看完整说明和示例

php bin/console doctrine:migrations:execute -h

php bin/console doctrine:migrations:migrate -h
