This note describes how to install python packages without Internet connectivity.

Download Packages in an Online Environment

First, use the pip download command in an environment with Internet access to download the required Python packages.

pip install boto3
pip freeze > requirements.txt
pip download --dest packages -r requirements.txt

This will save the packages and their dependencies to a directory named packages.

Transfer the Packages to the Offline Environment

Compress the downloaded packages into an archive file and transfer it to the target environment without Internet connectivity using a secure method like scp.

tar cvzf packages.gz ./packages
# Transfer the archive to the offline environment

Install Packages in the Offline Environment

Once transferred, extract the archive and use pip install with the --find-links and --no-index options to install the packages.

tar xvzf packages.gz
pip install -r requirements.txt --find-links packages --no-index

The --find-links option points to the local directory containing the packages, and --no-index ensures pip does not try to access the PyPI index.
