在以下位置完成教程：https://docs.docker.com/compose/wordpress/
运行docker compose我得到：

Initializing database
[Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
[ERROR] --initialize specified but the data directory has files in it. Aborting.
[ERROR] Aborting

尝试添加此处建议的参数：https://github.com/docker-library/mysql/issues/186https网址：github.com/docker-library/mysql/issues/69
但这似乎行不通：

services:
  db:
    image: mysql:5.7
    command: ["mysqld", "--ignore-db-dir=lost+found", "--explicit_defaults_for_timestamp"]
    volumes:
      - db_data:/var/lib/mysql
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: somewordpress
      MYSQL_DATABASE: wordpress
      MYSQL_USER: wordpress
      MYSQL_PASSWORD: wordpress

还有别的解决办法吗？
