kgritesh/pip-save

(Deprecated) A wrapper around pip that when called with an argument --save, stores the requested package with correct version to a requirement.txt file if it exist.

pip-save

DEPREACATED

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.

Installation

$ pip install pip-save

Usage

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>

Configuration

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

Configuration Options

• 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

pip-save's Issues

support local install

I'd like to install my packages locally similar to pip install --user <package-name>.

Not Working in Python 3.6

Not sure if this is intended, but keep getting this error when running pip-save:

Traceback (most recent call last):

specify python version

I'd like to specify which python version pip-save should use. My default python version is 2.7, but I'd like to use python3. I have a similar alias python2, pip2 and pip3. Hence, I can easily run both python versions. I'm missing something like pip2-save and pip3-save.
