docker不安装软件包Environs

Question

我试图使用命令docker compose exec web pipenv install'environs[django]==8.0.0'在docker中安装一个包“environs”，但是终端中没有发生任何事情，包也没有安装在容器中。原因是什么？ docker-compose.yml

version: '3.8'
services:
  web:
    build: .
    command: python /code/manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - 8000:8000
    depends_on:
      - db
    environment:
      - "DJANGO_SECRET_KEY=django-insecure-c@p4-@$$@#0deu2p5&-59#-1kv&@(ayfu*b+a+wt(i9j5p7&=p3"

  db:
    image: postgres:11
    volumes:
      - postgres_data:/var/lib/postgresql/data/
    environment:
      - "POSTGRES_HOST_AUTH_METHOD=trust"
volumes:
  postgres_data:
