Bypass confirmation prompt for pip uninstall
starting with pip version 7.1.2 you can run pip uninstall -y <python package(s)>
pip uninstall -y package1 package2 package3
or from file
pip uninstall -y -r requirements.txt
Pip does NOT include a --yes option (as of pip version 1.3.1).
WORKAROUND: pipe yes to it!
$ sudo ls # enter pw so not prompted again
$ /usr/bin/yes | sudo pip uninstall pymongo
If you want to uninstall every package from requirements.txt,
pip uninstall -y -r requirements.txt
