我正在尝试运行一个django-cookiecutter项目，但是在某些容器中却出现了ModuleNotFoundError: No module named 'iprestrict'错误。我检查了我们的存储库，使我的同事可以使用Windows的Docker和Linux的Docker成功构建和运行。我已经调试了一段时间，但是现在我茫然了，要求您的帮助。
这是我的设置：

为获得一个全新的开始，我在项目目录中运行了以下命令：
$ docker-compose down --volumes
$ docker-compose build --no-cache
该项目已成功构建，没有错误消息，这是最后几行，已删除了一堆软件包以提高可读性。可以看到，django-iprestrict已成功安装：
Successfully installed [...] django-environ-0.4.5 django-extensions-2.1.5 django-iprestrict-1.7.0 django-model-utils-3.1.2 [...]
这是Dockerfile中的相关部分：
FROM python:3.6.8-alpine
ENV PYTHONUNBUFFERED 1
[...]
COPY ./requirements /requirements
RUN pip install -r /requirements/local.txt
在local.txt中的软件包中有：
[...]
django==2.1.5 # https://www.djangoproject.com/
django-environ==0.4.5 # https://github.com/joke2k/django-environ
django-model-utils==3.1.2 # https://github.com/jazzband/django-model-utils
django-iprestrict==1.7.0 # https://github.com/muccg/django-iprestrict
[...]
来自docker-compose.yml：
services:
django:
build:
context: .
dockerfile: ./compose/local/django/Dockerfile
image: companyname_local_django
depends_on:
- postgres
# these configs need to be overriden by the local and prod service configurations
volumes:
- .:/app
env_file:
- ./.envs/.local/.django
- ./.envs/.local/.postgres
并且来自docker-compose.override.yml：
services:
django: &django
ports:
- "8000:8000"
command: /start
environment:
- TERM=xterm-256color
restart: on-failure
# these configs are overriding the values in docker-compose.yml django service configuration
volumes:
- webpack_build:/app/build
- .:/app
env_file:
- ./.envs/.local/.django
- ./.envs/.local/.postgres
postgres:
volumes:
- local_postgres_data:/var/lib/postgresql/data
- local_postgres_data_backups:/backups
ports:

celeryworker:
<<: *django
image: companyname_local_celeryworker
depends_on:
- postgres
ports: []
command: /start-celeryworker
celerybeat:

ports: []
command: /start-celerybeat
flower:
<<: *django

ports:

command: /start-flower
然后我尝试使用$ docker-compose up运行它，并得到以下错误消息：

celeryworker_1和flower_1容器的错误。
然后，我检查了安装在不同容器中的软件包，发现iprestrict，celerybeat和celeryworker中缺少flower，但django中却没有（它们会展开）：

如您所见，所有具有local.txt中定义的正确版本的软件包都在那里除外 django-iprestrict==1.7.0。
有人知道这可能是什么原因吗？谢谢！
