Why is PIP raising an AssertionError on pip freeze?

Question

My console:

desarrollador@desarrollador-HP-14-Notebook-PC1:~$ pip freeze  
Exception:  
Traceback (most recent call last):  
  File \"/usr/lib/python2.7/dist         


        

Answer 1

The problem is due to an old version of pip being installed. Run the following command to install a new version of pip:

sudo easy_install -U pip.
