Hi everyone
I apologize in advance if my question is not relevant to this forum but it made me really crazy and i am struggling with it for almost a week searching for solutions in the internet but none of them works for me
so here is my problem:
whatever package i install with pipenv it installs without any problem and add to Pipfile and Pipfile.lock
and in my code i can import libraries of that package and the IDE detect the package but when i run server it says No module named ‘some module’
to add some more details i ran pip freeze in virtual env and reportlab was there
so any help would be really appreciated
Thanks
I’d say the first thing to check would be to ensure that your virtual environment is active when your server is being started.
Beyond that, we’d need a lot more details including the specifics of how you’re running your server and the full traceback of the error you’re receiving to even begin helping you to diagnose this.

Hello Mohammad
I think your virtual environment is not active
so first check if it’s active or maybe env file is not in the same project directory
1-pipenv install -r requirements.txt
then
2-pipenv shell
then try to run your server and if still run into the same issue can you provide us with error screenshot
Side note: We discourage screenshots for submitting information except when absolutely necessary.
It’s a lot more useful to copy/paste the text of the traceback into the body of the post (surrounded by the lines of ``` as appropriate).

Yes Mr. ken you’re right
actually i dockerised my project so whenever i want to install a package first i run docker in detach mode
then run pipenv install
now here is the track back of my system after running those commands

There is nothing in your compose file that indicates that you are going to use the virtual environment in that container.
What is the docker file for your “web” container?
Side note: If you’re looking to produce a “production-quality” docker container for your Django app, this is not the way to do it. The runserver command is not appropriate for production use.
Quoting directly from the docs for runserver
DO NOT USE THIS SERVER IN A PRODUCTION SETTING. It has not gone through security audits or performance tests.
If you’re just doing this as an educational exercise, it’s probably ok. But if this is going to be something you want to rely upon, this most definitely is not the way to do it.
dockerfile
# Pull base image
FROM python:3.10
# Set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1
# Set work directory
WORKDIR /code
# Install dependencies
COPY Pipfile Pipfile.lock /code/
RUN pip install pipenv && pipenv install --system
# Copy project
COPY . /code/
EXPOSE 8000
There’s no need to use a virtual environment in a container such as this.
Add your other installation commands into your dockerfile so that everything is installed and ready to go.
Then install either gunicorn or uwsgi to make it a proper container for use.
Also add your command to run gunicorn in the container using the CMD directive.
Thanks
I am going to give it a try
i will let you know what the result is
so could you tell me more specific what to do
-
Add the commands into your dockerfile to “pip install” all the packages your project needs, including gunicorn
-
Add a CMD directive to run gunicorn
-
Don’t run any commands to install packages in a virturalenv. Don’t create a virtualenv. Don’t try to use a virtualenv.
you mean the way i formed my project with dockerfile, docker-compose.yml, pipfile and pipfile.lock is redundant and i can pack it up in one docker file?
You still need the dockerfile to create the container. You still need the docker-compose to run it. It’s the other stuff you don’t need.
alright thanks again
i am going to use your advice in action
