我正在做一个Laravel项目。我使用docer-compose/docker作为我的开发环境。
这是我的docker-compose. yml文件。

networks:
  myaneat-network:
    driver: "bridge"
volumes:
  myaneat-data:
    driver: "local"
  es-data:
    driver: "local"

我正在运行以下命令安装一个新的软件包。

docker-compose exec php-fpm composer require calebporzio/sushi

但是只有composer.json更新了，composer.lock没有更新。而且，包也没有下载到vendor文件夹中。我之前在工作。只是突然发生了这种情况。
我尝试了以下方法：

docker-compose exec php-fpm composer clearcache
docker-compose exec php-fpm composer clear-cache
docker-compose exec php-fpm composer dump-autoload
docker-compose exec php-fpm composer update --lock

可能的根本原因是什么？我如何修复它？
