To create an archive (from the official documentation: https://pip.pypa.io/en/latest/user_guide/#installation-bundles), perform the following:

1. Create a temporary directory:

      $ tempdir = $(mktemp -d /tmp/archive_dir)

2. Create a wheel file:

      $ pip wheel -r requirements.txt --wheel-dir = $tempdir

3. Let the OS know where to place the archive file:

      $ cwd = `pwd`

4. Change to the temporary directory and create the archive file:

      $ (cd "$tempdir"; tar -cjvf "$cwd/<archive>.tar.bz2" *)

To install from an archive, do the following:

1. Create a temporary directory:

      $ tempdir=$(mktemp -d /tmp/wheelhouse-XXXXX)

2. Change to the temporary directory and unarchive the file:

      $ (cd $tempdir; tar -xvf /path/to/<archive>.tar.bz2)

3. Use pip to install the unarchived files:

      $ pip install --force-reinstall --ignore-installed --upgrade --no-index --no-deps $tempdir/*
