Vendorising Python pips via Pipfile

vendored-pipenv.makefile

# Makefile-friendly version of:
#
#   pipenv run -- pip install -r <(pipenv lock -r) --target $PWD/vendored --no-deps

# You will need to add something like the following to your Main .py file:
#
#   import os
#   import sys
#   parent_dir = os.path.abspath(os.path.dirname(__file__))
#   # (Might need to adjust the path, e.g. adding '..' if appropriate)
#   vendor_dir = os.path.join(parent_dir, 'vendored')
#   # (Add vendor directory to module search path)
#   sys.path.append(vendor_dir)
