What doesn’t seem to be documented in the pip installation guide is that pip can bootstrap itself. You can install pip using pip without pip being already installed. No internet access is required, just an installation of Python and the pip wheel:
python pip-18.0-py2.py3-none-any.whl/pip install pip-18.0-py2.py3-none-any.whl
