ModuleNotFoundError：运行 Django + Docker 项目时没有名为“djoser”的模块

Question

To add registration to django-project, I decided to use 'djoser' library. But while making migrations with docker-compose run server python manage.py makemigrations , the same error raises:

Creating school-co_server_run ... done
Traceback (most recent call last):

ModuleNotFoundError: No module named 'djoser'
ERROR: 1

The thing is that I already pip installed djoser (using the newest update of pip), I froze djoser too with the help of requirements.txt:

asgiref==3.2.10
attrs==21.2.0
Django==3.1
django-environ==0.8.1
django-extensions==3.1.5
django-filter==21.1
djangorestframework==3.12.4
djangorestframework-camel-case==1.2.0
drf-spectacular==0.21.0
inflection==0.5.1
jsonschema==4.2.1
Markdown==3.3.6
mysqlclient==2.1.0
Pillow==8.4.0
pyrsistent==0.18.0
pytz==2021.3
PyYAML==6.0
sqlparse==0.4.2
uritemplate==4.1.1
djoser==2.0.1
pandas=1.1.3

But it still doesn't work. Section of 'settings.py' INSTALLED_APPS also is correct:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'base',
    'school_co',
    'django_extensions',
    'rest_framework',
    'rest_framework.authtoken',
    'drf_spectacular',
    'djoser',
    'rest_framework_simplejwt',
]

I use docker-compose, and here is the web/Dockerfile in which the operation happens:

FROM python:3.9-slim-bullseye

ENV PYTHONUNBUFFERED=1

RUN set -ex \
    && apt-get update \
    && apt-get install curl default-libmysqlclient-dev gcc -y \
    && rm -rf /var/lib/apt/lists/*

RUN useradd --create-home --shell /bin/bash --home /home/web web
USER web
WORKDIR /home/web

COPY etc/requirements.txt ./etc/requirements.txt

RUN set -ex \
    && python -m venv /home/web/venv \
    && ./venv/bin/pip install --upgrade pip \
    && ./venv/bin/pip install --no-cache-dir -r ./etc/requirements.txt

COPY etc/env ./etc/env

ENV VIRTUAL_ENV /home/web/venv
ENV PATH /home/web/venv/bin:$PATH
WORKDIR /home/web/server

Answer 1

Seems that 'djoser' doesn't work without 'pandas'.
