出于开发原因，您可能（像我一样）试图将所有已导出的配置从某个现有站点（从此处称为example.com）导入到本地（localhost/PROJECT_NAME）中，但这目前不直接支持（2019年中），您必须首先导入数据库，有关更多信息，请参见下文。
example.com/admin/config/development/backup_migrate）导出并下载数据库。DATABASE_NAME），然后使用PhpMyAdmin（或类似的名称，例如http://localhost/phpmyadmin/）导入以前导出的数据库。settings.local.php文件存在（在./sites/default/settings目录中），当不存在时创建并配置它，例如：<?php
