Checks pip requirements against installed versions, and other related tools.

Project description

  • Checks requirements.txt against installed packages, or latest versions available on PyPi.
  • Shows latest package information from PyPi (for requirements.txt or any package).
  • Searches requirements.txt for text/regex patterns.
  • Sorts requirements.txt lines in place.
  • Finds duplicate entries in requirements.txt.


This tool is installable with pip:

pip install requirementz

The command is called requirementz.


Requirementz has several python dependencies, all installable with pip. A requirements.txt is provided, for easy installation.

If you’ve cloned the repo, you can run pip install -r requirements.txt to install all of them. Otherwise, pip install requirementz should install all dependencies for you.

                           Useful for use with -e, to get a list of
                           packages to install or upgrade.

Check (installed packages)

Check requirements.txt against installed package versions.


Here you can see that the colr >= 0.7.6 requirement was not satisfied, because 0.7.5 is installed:



Show package location while checking:

requirementz -L


Check (latest pypi version)

Check requirements.txt against installed package versions, and the latest pypi version.

requirementz -C


Show package location while checking:

requirementz -C -L


Show pypi info for packages.

-P will show pypi information for all packages in requirements.txt:

requirementz -P


You can do this for any package, whether it’s installed or not:

requirementz antigravity


You can use more than one package name.

Find duplicate requirements

Any duplicate entries will be listed by name, with a count of duplicates.

requirementz -d


This hasn’t been tested very well with CVS or local requirements. Any help in that area would be appreciated, as I haven’t had to use those requirement types.
