What is pip's equivalent of `npm install package --save-dev`?

Question

In nodejs, I can do npm install package --save-dev to save the installed package into the package.

How do I achieve the same thing in Python package manager

Answer 1

I've created python package that wraps around the actual pip called pipm. All pip commands will work as it is, plus they will be reflected in the requirements file. Unlike pip-save(similar tool I found and wasn't able to use) it can handle many files and environments(test, dev, production, etc. ). It also has command to upgrade all/any of your dependencies.

installation

pipm install pkg-name

installation as development dependency

pipm install pkg-name --dev

installation as testing dependency

pipm install pkg-name --test

removal

pipm uninstall pkg-name

update all your dependencies

pipm update

install all your dependencies from the requirements file

pipm install

including development dependencies

pipm install --dev
