PyPICache is a relatively easy-to-make server that serves content from the Python Packaging Index and makes it available offline using a Raspberry Pi, allowing you to use pip without Internet access.
To set up PyPICache initially, you need an Internet connection (to download the required software and clone PyPI), and a Raspberry Pi(or similar computer) with a wireless chip. The PyPICache device creates a WIFI network that laptops or any WIFI-enabled devices can connect to and install Python packages from. It clones the PyPI repository to local storage, organises the packages, and serves them using pypiserver and nginx as a caching and reverse proxy.
