我正在学习 docker，我想制作我的 python django docker 镜像在我的 mac 上运行 我创建了 3 个文件:
1: docker-compose
version: '3'
services:
db:
image: postgres
web:
build: .
command: python3 manage.py runserver 0.0.0.0:8000
volumes:
- .:/code
ports:
- "8000:8000"
depends_on:
- db
2:Dockerfile
FROM python:3
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
ADD requirements.txt /code/
RUN pip install -r requirements.txt
ADD . /code/
3:要求
Django>=1.8,<2.0
psycopg2
然后我运行 sudo docker-compose run web django-admin.py startproject composeexample 。 我已经在我的目录中创建了官方示例文件
但是当我运行 docker-compose
出现错误，运行失败

现在有人可以帮助我吗？我很困惑。 谢谢。
请您参考如下方法:
尽管将我的 requirements.txt 文件更改为:
Django >=2
心理战2
还有其他建议吗？我几乎没有想法了。我一直在使用 https://docs.docker.com/compose/django/#connect-the-database .据我所知，我已根据该网页按照书上的说明完成了所有操作。
