Django在安装django后卸载-调试-工具栏中的停靠容器，如何安装它而不安装django？

Question

我试图在我的容器中安装django调试工具栏

[shub@debian teamwave](task-details-api)$ docker exec -it teamwave_backend_1 pip install django-debug-toolbar Collecting django-debug-toolbar   Downloading https://files.pythonhosted.org/packages/01/9a/3db232bd15882d90d3c53de1f34ce0a522327849593c9198899713267cfe/django_debug_toolbar-1.11-py2.py3-none-any.whl (201kB)

我试过运行容器并安装django

启动teamwave_backend_1 ..。完成对teamwave_backend_1的附加

backend_1  | Traceback (most recent call last):
backend_1  |   File "manage.py", line 8, in <module>
backend_1  |     from django.core.management import execute_from_command_line
backend_1  | ImportError: No module named django.core.management
teamwave_backend_1 exited with code 1

我后来用docker-compose build修复了django，但是我也想要django-调试-工具栏。

这是我的docker-compose.yml

version: '3'

services:
  db:
    image: postgres:10-alpine
    environment:
      - POSTGRES_PASSWORD=dsdbadmin
      - POSTGRES_DB=tm_v1.1
    volumes:
      - pgdata:/var/lib/postgresql/data
      - ./docker-entrypoint-initdb.d:/docker-entrypoint-initdb.d
  backend:
    build: .
    volumes:
      - .:/backend
    ports:
      - "8000:8000"
    depends_on:
      - db
      - redis
  redis:
    image: redis:4-alpine

volumes:
  pgdata:

这是我的Dockerfile

FROM python:2
ENV PYTHONUNBUFFERED 1
WORKDIR /backend
ADD req.txt /backend/
RUN pip install --upgrade pip
RUN pip install -r req.txt
ADD . /backend/

ENTRYPOINT ["python", "manage.py", "runserver", "0.0.0.0:8000"]

EXPOSE 8000

我使用docker-compose up运行我的容器

从django-debug-toolbar安装最新版本将安装Django-1.11.23并卸载旧的Django版本。

您可以尝试为django-debug-toolbar找到正确的Django-1.8。
