Question

Hi I just moved my Django project on the docker. And created an image successfully. But when,I tried running it using

docker run -p 8000:8000 my-django-app

I am getting the error

ModuleNotFoundError: No module named 'bootstrap5'

I have even added the bootstrap5 in the django settings

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'firstapp',
    'bootstrap5',
]

And I have added it in the requriments.txt

django-bootstrap5==23.3

This if my dockerfile

# Use an official Python runtime as the base image
FROM python:3.11.1

# Set the working directory in the container
WORKDIR /app

# Copy the requirements.txt file and install the Python dependencies
COPY requirements.txt /app/
RUN pip install --no-cache-dir -r requirements.txt

# Copy the rest of the application code
COPY . /app/

# Expose the port the Django application will run on
EXPOSE 8000

# Set the command to start the Django development server
CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]

I have installed it using

pip install django-bootstrap-v5

I checked the version of the bootstrap5 as well as the settings.py but everything seems fine. I am trying to move this existing django project on the docker.

Answer 1

django-bootstrap5 and django-bootstrap-v5 these are different packages. And which is using different app names as well.

In your case you have installed django-bootstrap-v5 but in the requirements.txt you mentioned django-bootstrap5==23.3.

You need to updated it as django-bootstrap-v5==1.0.11.

Use this command to generate requirements.txt with lists of all the dependencies.

pip freeze > requirements.txt

Note : Adding/updating the requirements.txt manually is generally not recommended. It may leads to inconsistencies in the package versions. Instead it is best to generate it automatically.
