Permission denied when uninstalling numpy with pip

Question

I am trying to uninstall Numpy via Pip but this error comes up:

$ pip uninstall numpy

Uninstalling numpy:
  /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy-1.6.2-py2.7.egg-info
Proceed (y/n)? y
Exception:

 OSError: [Errno 13] Permission denied: '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy-1.6.2-py2.7.egg-info'

No clue what the best way to proceed from here would be. I would like to uninstall numpy completely then reinstall.

Answer 1

try:

sudo pip uninstall numpy

or, if it doesn't work:

sudo apt-get remove python-numpy

Answer 2

You need to add sudo, sudo pip uninstall numpy
