错误：无法从“11.7”确定 PostgreSQL 版本

我找到了一个 Django 项目，但未能通过以下方式在 Docker 容器中运行：

1. git clone https://github.com/hotdogee/django-blast.git

我有以下 Dockerfile：

FROM python:2
ENV PYTHONUNBUFFERED=1
WORKDIR /code
COPY requirements.txt /code/
RUN pip install -r requirements.txt
COPY . /code/

因为docker-compose.yml我使用：

version: "3"

services:
  db:
    image: postgres
    volumes:
      - ./data/db:/var/lib/postgresql/data
    environment:
      - POSTGRES_DB=postgres
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=postgres
  web:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - db

接下来，我遇到了这个错误：

$ docker-compose build
...

我错过了什么？
