pip is used to effortlessly control installation and life-cycle of publically available Python packages from their online repositories.
However, every Python developer sooner or later runs into simple issue. How to upgrade all installed Python packages at the same time?
Apparently, pip has no build in mechanism for that. This is why I have decided to provide this simple one-liner,
pip freeze — local | grep -v ‘^\-e’ | cut -d = -f 1 | xargs -n1 pip install -U
Note: Use at your own risk. Some of your packages may require root privileges. Use the version below
Version with root privileges:
sudo pip2 freeze — local | grep -v ‘^\-e’ | cut -d = -f 1 | xargs -n1 sudo pip2 install -U
