我创建了一个新的symfony4项目，并想创建一个新的数据库。我正在学习这个教程，但没法用。运行时

php bin/console doctrine:database:create

我总是犯同样的错误：

In AbstractMySQLDriver.php line 112:
    An exception occurred in driver: SQLSTATE[HY000] [1045] Access denied for user 'user_1'@'localhost' (using password: YES)

In PDOConnection.php line 50:
    SQLSTATE[HY000] [1045] Access denied for user 'user_1'@'localhost' (using password: YES)

In PDOConnection.php line 46:
    SQLSTATE[HY000] [1045] Access denied for user 'user_1'@'localhost' (using password: YES)

在教程之后，我在.env文件中配置了数据库url，但它似乎没有改变任何东西。

DATABASE_URL=mysql://user_1:secretPassword@127.0.0.1:3306/db_name

my config/packages/document.yaml配置：

parameters:
    env(DATABASE_URL): ''

doctrine:
    dbal:
        # configure these for your database server
        driver: 'pdo_mysql'
        server_version: '5.7'
        charset: utf8mb4
        default_table_options:
            charset: utf8mb4
            collate: utf8mb4_unicode_ci

        url: '%env(resolve:DATABASE_URL)%'
    orm:
        auto_generate_proxy_classes: '%kernel.debug%'
        naming_strategy: doctrine.orm.naming_strategy.underscore
        auto_mapping: true
        mappings:
            App:
                is_bundle: false
                type: annotation
                dir: '%kernel.project_dir%/src/Entity'
                prefix: 'App\Entity'
                alias: App

什么都试过了，似乎都没用。任何帮助都将不胜感激。
