我的docker-compose配置文件有问题。我的目标是运行一个带有docker-compose文件的Next.js应用程序，并启用热重载。
从其Dockerfile运行Next.js应用程序可以工作，但热重载不起作用。从docker-compose文件运行Next.js应用程序会触发一个错误：/bin/sh: next: not found我不知道是什么错了。

Dockerfile：（摘自Next.js文档网站）

[请注意，这是一个多阶段构建，但我只引用docker-compose文件中的builder阶段。]

docker-compose.yml：

  db:
    image: postgres
    volumes:
      - ./tmp/db:/var/lib/postgresql/data
    environment:
      POSTGRES_PASSWORD: ${POSTGRESQL_PASSWORD}
  backend:
    build: .
    command: bash -c "rm -f tmp/pids/server.pid && bundle exec rails s -p 3000 -b '0.0.0.0'"
    volumes:
      - .:/myapp
    ports:
      - "3000:3000"
    depends_on:
      - db
    environment:
      DATABASE_USERNAME: ${MYAPP_DATABASE_USERNAME}
      DATABASE_PASSWORD: ${POSTGRESQL_PASSWORD}
  frontend:
    build:
      context: ./frontend
      dockerfile: Dockerfile
      target: builder
    command: yarn dev
    volumes:
      - ./frontend:/app
    expose:
      - "3001"
    ports:
      - "3001:3001"
    depends_on:
      - backend
    environment:
      FRONTEND_BUILD: ${FRONTEND_BUILD}
      PORT: 3001

package.json：

{
  "private": true,
  "scripts": {
    "dev": "next dev",
    "build": "next build",
    "start": "next start"
  },
  "dependencies": {
    "next": "latest",
    "react": "^18.1.0",
    "react-dom": "^18.1.0"
  }
}

当从docker-compose.yml调用yarn dev时，它实际上调用了next dev，这就是它触发错误/bin/sh: next: not found的时候。但是，直接从Dockerfile运行容器可以正常工作，不会导致此错误。

【更新】：

如果我从docker-compse.yml文件中删除volume属性，我不会得到/bin/sh: next: not found错误，容器会运行，但是，我现在不会得到我正在寻找的热重载特性。你知道为什么卷会在/bin/sh next命令下出错吗？
