Im installing pipenv in my docker:

RUN pip install pipenv
RUN cd /my/app/path/ && pipenv install
RUN cd /my/app/path/ && pipenv shell

Im getting the error:

Traceback (most recent call last):

    sys.exit(cli())

    return s.startswith('/')
AttributeError: 'NoneType' object has no attribute 'startswith'

If I run

RUN cd /my/app/path/ && pipenv install --system

instead, im getting another error:

build   30-Sep-2017 16:50:49    [0mSending build context to Docker daemon 40.96 kB

But when I instead do the following:

RUN pip install pipenv
RUN cd /my/app/path && pipenv install
RUN cd /my/app/path && pipenv install --system

It is working...

So two question: First: Why is pipenv shell giving me this error and Second: Why do I have to do pipenv install before pipenv install --system to get it working?

I would like to use pipenv to create virtual environments with different python versions and differne dependency versions.

Considering your problem, as I know it the easiest way is to update to the latest version of pipenv. It is still in development, so problems are fixed very soon.

We are using pipenv with docker in production. And we really like it. There are several things to keep in mind:

  1. You need to use --system flag, so it will install all packages into the system python, and not into the virtualenv. Since docker containers do not need to have virtualenvs
  2. You need to use --deploy flag, so your build will fail if your Pipfile.lock is out of date
  3. You need to use --ignore-pipfile, so it won't mess with our setup

Check the official docs to be sure that this information is up-to-date.

All in all:

pipenv install --system --deploy --ignore-pipfile

There's also one more thing. If you are using the same Dockerfile for both development and production it would be very nice to also use --dev flag for the development environment only.

Also, check out our django project template to see the full example: wemake-django-template
