Checks packages in your active environment against pip requirements files
Piplint validates your current environment with the requirements files you’ve specified. It will ensure that any requirement listed exists within the environment, and within the bounds of the versions specified.
source env/bin/activate piplint requirements/*.txt
You can also pass --strict if you want to enfoce things like case sensitivity on package names.
