使用 docker-compose 在 docker 中运行任何 manage.py 命令时，没有名为 django 的模块错误

Question

I'm getting ImportError: No module named django when trying to up my containers running docker-compose up .

Here's my scenario:

Dockerfile

FROM python:2.7
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
ADD requirements.txt /code/
RUN pip install -r requirements.txt
ADD . /code/

docker-compose.yml

version: '2'
services:
  db:
    image: postgres
  web:
    build: .
    command: bash -c "python manage.py runserver"
    volumes:
      - .:/code
    expose:
      - "8000"
    links:
      - db:db

manage.py

import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myapp.settings")

    from django.core.management import execute_from_command_line
    execute_from_command_line(sys.argv)

• The containers were built successfully
• My packages are present in the container (I get them when I run pip freeze )

I've changed the manage.py content for

import django
print django.get_version()

and it worked.

This is basically the same example as in this tutorial , except for starting a new project.

Answer 1

My solution was to simply call

python3.6 manage.py ...

instead of

python manage.py ...

Answer 2

I had to ensure that the module was imported along with app name:

from uploadapi.importers import Status

instead of

from importers upload Status
