Using a local cache for pip packages

gistfile1.sh

# edit your .bashrc

nano ${HOME}/.bashrc

if [ ! -d "${HOME}/.pip-packages" ]; then
  mkdir ${HOME}/.pip-packages
fi

alias pipcache='pip install --download ${HOME}/.pip-packages'
alias pipinstall='pip install --no-index --find-links=file://${HOME}/.pip-packages/'

# The first downloads the packages to my local cache, the second installs them from the cache.
# Usage is probably fairly obvious:

pipcache Django==1.7 # Put Django-1.7-py2.py3-none-any.whl in ~/.pip-packages
pipinstall Django==1.7 # Install ~/.pip-packages/Django-1.7-py2.py3-none-any.whl

pipcache -r requirements.txt # Cache all the requirements of a project
pipinstall -r requirements.txt # Install all requirements from the cache
