Question

在一个全新的项目（Symfony 4.1）中，我尝试使用 SQLite 数据库。因此，我将 .env 更改为：

###> doctrine/doctrine-bundle ###
# Format described at http://docs.doctrine-project.org/projects/doctrine-dbal/en/latest/reference/configuration.html#connecting-using-a-url
# For an SQLite database, use: "sqlite:///%kernel.project_dir%/var/data.db"
# Configure your db driver and server_version in config/packages/doctrine.yaml
#DATABASE_URL=mysql://db_user:db_password@127.0.0.1:3306/db_name
DATABASE_URL=sqlite:///%kernel.project_dir%/var/data.db
###< doctrine/doctrine-bundle ###

文件 doctrine.yaml 外观

parameters:
    # Adds a fallback DATABASE_URL if the env var is not set.
    # This allows you to run cache:warmup even if your
    # environment variables are not available yet.
    # You should not need to change this value.
    env(DATABASE_URL): ''

doctrine:
    dbal:
        # configure these for your database server
        driver: 'pdo_sqlite'
        server_version: '5.7'
        charset: utf8mb4
        default_table_options:
            charset: utf8mb4
            collate: utf8mb4_unicode_ci
        url: '%env(resolve:DATABASE_URL)%'

但是当我尝试创建数据库时：

php bin/console doctrine:database:create

发生此错误：

In CreateDatabaseDoctrineCommand.php line 78:
Connection does not contain a 'path' or 'dbname' parameter and cannot be dropped.

事实是url: '%env(resolve:DATABASE_URL)%'无法递归解析我的 .env 配置的%kernel.project_dir%部分。这似乎是一个已知问题，已在2017年为Symfony 3.4修复（因此，我敢打赌，自2017年以来，该问题已在4.1等最新分支中得到解决）

有趣的来源：

https://github.com/symfony/flex/issues/129

https://github.com/symfony/symfony/pull/23901

请注意，我在文件 doctrine.yaml 中找到了两种解决方法：

parameters:
    # Adds a fallback DATABASE_URL if the env var is not set.
    # This allows you to run cache:warmup even if your
    # environment variables are not available yet.
    # You should not need to change this value.
    env(DATABASE_URL): 'sqlite:///%kernel.project_dir%/var/data.db'

但是明确（如前所述），我不应该修改该参数... 或者

doctrine:
    dbal:
        # configure these for your database server
        driver: 'pdo_sqlite'
        server_version: '5.7'
        charset: utf8mb4
        default_table_options:
            charset: utf8mb4
            collate: utf8mb4_unicode_ci
        url: 'sqlite:///%kernel.project_dir%/var/data.db'

当然，在 .env 文件中填充sqlite connexion字符串比 doctrine.yaml 文件更干净，因为这取决于环境设置... < / p>

您是否知道如何使其在 .env 文件中起作用？
