Installing Python Packages from Local FileSystem to Virtualenv with pip

Utilizing pip to install packages from the local file system is indeed feasible. Once you have created the distribution tarball for your package by running python setup.py sdist, you can proceed with the installation within a virtual environment.

Method:

To install packages from a specific local location while preserving the ability to install from PyPI, you can leverage the -e or --editable option in pip. This option allows you to install a project in "editable" mode, enabling you to make changes to the package code without the need to reinstall.

Command:

Use the following command to install your package:

pip install -e /srv/pkg

Here, /srv/pkg represents the top-level directory containing the setup.py file for your package.

By employing this approach, pip will add /srv/pkg as an additional search path for packages. When you execute pip install mypackage without specifying a specific location, pip will first attempt to locate the package in /srv/pkg. If it's found there, it will be installed from that location. If not, pip will continue searching for the package on PyPI.
