Docker error while running: no module named 'pytz'-CodePudding

When running docker-compose run server python manage.py makemigrations (making migrations) and getting this error:

django.template.library.InvalidTemplateLibrary: Invalid template library specified. 
ImportError raised when trying to load 'rest_framework.templatetags.rest_framework': No mo
dule named 'pytz'

My docker-compose.yml:

version: '3'

services:
  db:
    build: ./etc/docker/db
    restart: always
    volumes:
      - ./var/volumes/dbdata:/var/lib/mysql
    env_file:

  server: &web
    build:

      dockerfile: ./etc/docker/web/Dockerfile
    volumes:
      - ./server:/home/web/server
#    depends_on:

    ports:
      - "8080:8080"
    command: ["python", "manage.py", "runserver", "0.0.0.0:8080"]

I tried installing pytz through pip install pytz, but I still get the same error. Now I'm confused, please explain what the problem could be.

CodePudding user response：

You need to install all dependencies inside Dockerfile. Your dockerfile should contains something like

COPY requirements.txt /app/requirements.txt  
RUN pip install -r /app/requirements.txt

Where your requirements.txt contains all libraries you need to run the server.

or you can just install libs you need inside dockerfile

RUN pip install pytz django etc...
