Ubuntu – pip won’t run. throws errors instead


I am running into problems when ever I run pip with any arguments or flags. I've tried doing apt-get install --reinstall python-pip but it does not help and am at a loss how to fix this

Version of Ubuntu

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.1 LTS
Release:    14.04
Codename:   trusty

Version of Python

$ python --version
Python 2.7.6

Pip version

$ dpkg -l | grep pip
ii  python-pip     1.5.4-1     all     alternative Python package installer

Error, I get the exact same error no matter what arguments or flags I try.

$ pip

Seems to be a bug that it is reported here

It should work if you install a later version of pip.

You can remove the current pip installation with:

sudo apt-get purge python-pip

Then install it from github(it is a later version):

wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py
python get-pip.py

If it still won't work try this as it says so in the installation documentation(after you installed the new version):

To enable the use of pip from the command line, ensure the Scripts subdirectory of your Python installation is available on the system PATH. (This is not done automatically.)
