I no longer use/support this library. A much better approach to solve this problem is now available at pipenv. Strongly recommend to try that out

pip-save is a simple wrapper around pip so as to add npm --save style functionality to pip.

Currently its a big pain while installing new dependencies using pip. After installing the dependency, you need to figure out the version number and then manually add it to your requirements file. pip-save allows you to install/uninstall any dependecy and automatically add/remove it to/from your requirements file using one command only.

Since its only a wrapper around pip install and uninstall commands, it accepts all options/config as these commands.

$ pip install pip-save

To Install a package and add it to your requirements.tx

$ pip-save install [<list of packages>]

To upgrade a package

$ pip-save install --upgrade [<list of packages>]

To uninstall a package and remove it from your requirements.txt

$ pip-save uninstall [<list of packages>]

To install a package from VCS and add it to your requirements file

$ pip-save install -e <url of the repo>

For most users the default configuration of pip-save should be fine. If you do want to change pip-save's defaults you do so by adding configuration options to a configuration file. If a .pipconfig file exists in the current working directory, its automatically loaded.

Here is an example of available options along with their default values.

[pip-save]
requirements = requirements.txt
use_compatible = False

• requirements:- path to the requirements file to be used. Default value is requirements.txt Can be overwritten by using command line option -r or --requirement

• use_compatible:- whether to use compatible version specifier instead of exact versions. Default value is False. Can be overwritten by using command line flag --use-compatible
