PIP Chill - Make requirements with only the packages you need

Like pip freeze but lists only the packages that are not dependencies of installed packages.

• Free software: GNU General Public License v3
• Documentation: https://pip-chill.readthedocs.io.

Features

Generates a requirements file without any packages that depend on other packages in the file.

Usage

Suppose you have installed in your virtualenv a couple packages. When you run pip freeze, you’ll get a list of all packages installed, with all dependencies. If one of the packages you installed ceases to depend on an already installed package, you have to manually remove it from the list. The list also makes no distinction about the packages you actually care about and packages your packages care about, making the requirements file bloated and, ultimately, inaccurate.

On your terminal, run:

$ pip-chill
asciitree==0.3.1
autopep8==1.2.4
beautifulsoup4==4.4.0
bleach==1.4.1
cookiecutter==1.4.0
coverage==3.7.1
django-argonauts==1.0.1
...

Or, if you want it without version numbers:

$ pip-chill --no-version
asciitree
autopep8
beautifulsoup4
bleach
cookiecutter
coverage
django-argonauts
...

Or, if you want to list package dependencies too:

$ pip-chill -v
asciitree==0.3.1
autopep8==1.2.4
beautifulsoup4==4.4.0
bleach==1.4.1
cookiecutter==1.4.0
coverage==3.7.1
