使用 docker 时无法使用 pipenv 安装软件包

Question

我正在使用 cookiecutter-django 和 pipenv 来设置项目。我正在尝试使用 docker，但是我收到的错误为ERROR: Service 'django' failed to build: The command '/bin/sh -c pipenv install' returned a non-zero code: 1。

要运行 docker，我使用了以下命令

docker-compose -f local.yml up -d

这是我的 docker 文件

local.yml

version: '3'

volumes:
  local_postgres_data: {}
  local_postgres_data_backups: {}

services:
  django: &django
    build:
      context: .
      dockerfile: ./compose/local/django/Dockerfile
    image: tryavel_local_django
    depends_on:
      - postgres
      - mailhog
    volumes:
      - .:/app
    env_file:
      - ./.envs/.local/.django
      - ./.envs/.local/.postgres
    ports:
      - "8000:8000"
    command: /start

      - local_postgres_data_backups:/backups
    env_file:

  mailhog:
    image: mailhog/mailhog:v1.0.0
    ports:
      - "8025:8025"

  redis:
    image: redis:5.0

  celeryworker:
    <<: *django
    image: tryavel_local_celeryworker
    depends_on:
      - redis
      - postgres
      - mailhog
    ports: []
    command: /start-celeryworker

  celerybeat:
    <<: *django
    image: tryavel_local_celerybeat
    depends_on:
      - redis
      - postgres
      - mailhog
    ports: []
    command: /start-celerybeat

  flower:
    <<: *django
    image: tryavel_local_flower
    ports:
      - "5555:5555"
    command: /start-flower

为什么我会遇到 pipenv 问题？

当我改为使用命令 pipenv install --system 时，我得到以下错误

Answer 1

当你使用 --system. Pipfile.lock 是必需的。确保将 pipfile.lock 复制到正确的目录

Answer 2

你只需要 cd 到 Dockerfile 中的 /app

# Requirements are installed here to ensure they will be cached.
RUN pip3 install --upgrade pip
RUN pip3 install pipenv
COPY Pipfile* /app/
RUN cd /app && pipenv install
