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
Traceback (most recent call last): File "/usr/bin/pip", line 9, in <module> load_entry_point('pip==1.5.4', 'console_scripts', 'pip')() File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 351, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2363, in load_entry_point return ep.load() File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2088, in load entry = __import__(self.module_name, globals(),globals(), ['__name__']) File "/usr/lib/python2.7/dist-packages/pip/__init__.py", line 11, in <module> from pip.vcs import git, mercurial, subversion, bazaar # noqa File "/usr/lib/python2.7/dist-packages/pip/vcs/mercurial.py", line 9, in <module> from pip.download import path_to_url File "/usr/lib/python2.7/dist-packages/pip/download.py", line 25, in <module> from requests.compat import IncompleteRead

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
python get-pip.py

Edit
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.)

This problem is caused by a mismatch between your pip installation and your requests installation. First remove the python-pip package and then install the latest version of pip. Open the terminal and type:

sudo apt remove python-pip
sudo apt install python-setuptools
sudo easy_install -U pip

To update pip for Python 3.x replace python-pip with python3-pip, replace python-setuptools with python3-setuptools, and replace easy_install with easy_install3.

Well, the get-pip.py script from github is outdated, and the latest version is on pypa as follows:

sudo apt-get purge python-pip
wget
python get-pip.py

I had the same error and same Ubuntu versions. easy_install was not working either. Doing apt-get --reinstall had not worked.

You might try recompiling:

sudo python
>>>import compileall
>>>compileall.compile_dir('/usr/lib/python2.7', force=True)

now "pip list" works (I had previously removed all the pyc files but I don't think it is necessary or safe)

Create a Symbolic link to /user/bin

sudo ln -s /usr/local/bin/pip /usr/bin/

Reinstalling python-pip from this website worked for me:

sudo apt-get purge python-pip
wget
python get-pip.py --user
