pipenv run does not support a --dev flag

Is your feature request related to a problem? Please describe.

pipenv shell and pipenv run creates a virtual environment automatically if one does not already exists. However, they do not install development dependencies by default. As such I have to run pipenv install --dev before using these commands. An example where I need to use pipenv run is in CI scripts as I do not have a tty.

Describe the solution you’d like

It would be ideal to be able to just run pipenv shell --dev or pipenv run --dev <command> in order to also install development dependencies.

Describe alternatives you’ve considered

My main wish would be that pipenv install (or pipenv shell or pipenv run <command>) actually installs development dependences by default. And that pipenv install --production would install all other dependencies. The reason for this is that most often to install into production you do that in CI scripts so it’s easy to always have a --production flag there. However, in development many developers often forget to add the --dev flag and then gets confused as to why some module import does not work when running scripts. I see this problem all the time for colleagues new to Pipenv. This is due that in development the pipenv installation is a manual step.

npm does it the other way around and it feels more natural to just have to issue npm install where it also installs development packages.

Additional context

Add any other context or screenshots about the feature request here. It may be a good idea to mention that platform and Python version you are on.

@techalchemy Understandable it is a breaking change, that might be something to consider for a major release.

Is there an idea to add --dev to pipenv run and pipenv shell? As those two are most likely supposed to be used in development? Those commands seemed aimed at development and not production, right?

This is a delibrate design decision because npm’s default to install all dependencies results in (IMO) people installing dev dependencies everywhere. Pipenv does this the other way around to encourage users to have a workable production environment, with develop requirements more “truly optional”. ~It is also the general direction most project managers work, with npm (and yarn, for this matter) being the exception rather than the rule.~ (Not correct, see discussion below.) The decision is of course open for discuss, but you’ll need a better reason than “because that’s how node does it”.
