Build Status

Python package management workflow using pip, requirements file & setup.cfg as its metadata. (For the time being and old world of python)


  • Adviced to install only inside virtualenv as this will replace pip executable

Install from PyPI

pip install pipm


  • This tool manipulates all your requirements file. So be sure to use version control software or take backup of your files to keep track of changes.


Both pip and pipm command will work as the same. Create an alias as alias pip=pipm and you are good to go.

install all your dependencies from the requirements file

  • to install only from requirements.txt

pipm install

  • to install from all *requirements*.txt

pipm install --all


pipm install pkg-name or pip install pkg-name

installation as development dependency

pipm install pkg-name --dev

installation as testing dependency

pipm install pkg-name --test


pipm uninstall pkg-name

update all your dependencies

pipm update

including development dependencies

pipm install --dev


  1. install

    • a wrapper around standard pip install command and accepts all the standard options

    Below are the things that pipm brings to the table

    1. Extra functionality
      • when package names are given it will be saved to the requirements.txt file in the current directory. If you have requirements directory structure with base.txt inside then that file will be used. Otherwise it will create one in the current directory.
      • when no package name is given then it is equivalent to -r requirements.txt and it will install all requirements from the current directory
    2. Additional options: the below saves to file when package name given otherwise equivalent to passing requirements file name.
      1. --dev - saves to development requirements
      2. --prod - saves to production requirements
      3. --test - saves to testing requirements
      4. --env <name> - if you have any special set of requirements that belong to a separate file you could pass the name here. It will search for the matching one in the following pattern <name>-requirements.txt or requirements/<name>.txt or requirements-<name>.txt
  2. uninstall

    • a wrapper around standard pip uninstall command
    • alias rm is available
    • when uninstalling a package, this command also checks packages that are no longer required by any of user installed packages and removes them
    • ofcourse it removes the packages from requirements files
  3. update

    • new command
    • equivalent to calling pip install with --upgrade flag
    • update a single package or the whole environment when no argument given.
    • by default the packages are updated interactively
      • set --auto-update to disable this
  4. save/freeze

    • extends the standard freeze command to save the currently installed packages


  1. Just a wrapper around the standard pip's install/uninstall command. So all the cli options will work
  2. Handles multiple requirements files
  3. No new set of files. requirements files contain pinned dependecies and setup.cfg contain abstract dependencies.


  • clone the repository and create new virtualenv
git clone
cd pipm
pew new pipm -a .
pip install -r dev-requirements.txt
  • to test from local sources
pip install -e .
  • Commit message should follow this style-guide.


  • run invoke test from the root directory.

Version compatibility

the package is versioned in accordance with pip major version number. pipm-9.* will be compatible with pip-9 and such.

Alternatives and their problems (IMHO)

  1. pipenv
    • good for local development with only one virtual environment per project
    • Not good when we need to deploy over production server or keep multiple virtuals-envs
    • it is better to use pew alone instead of the shell command that comes with this
  2. pip-tools
    • another set of files to keep track of, additional commands to remember
  3. poetry
    • better than pipenv and do not interfere much in environment management with pew
    • the problems I faced are related to installing dependencies in remote servers/docker environments. As the project matures this problem might get resolved.


  • rm will check whether a package is present in setup.cfg
