pip uninstall on El Capitan

[hawesie]

The command
pip freeze | xargs sudo pip uninstall -y
no longer works on El Capitan as the new security layer prevents some files being deleted which pip owns (or thinks it owns). It fails on the first system dependency, which is altgraph on my machine:

(output, for future googlers)

Uninstalling altgraph-0.10.2:

The following removes those installs which can be done by the user

#!/bin/bash
for i in $( pip freeze ); do
    sudo pip uninstall -y $i
done
