Unable to uninstall with pip

Question

As doing exercise 46 on learnpythonthehardway, I run into an issue with uninstallation.

Background

My package showed is created as:

├── bin
├── docs
├── HELLOWORLD
│   ├── helloworld.py
│   ├── __init__.py
├── setup.py
└── tests
    ├── HELLOWORLD_tests.py
    ├── __init__.py

THe way I installed the packages:

run python setup.py sdist to create a tar.gz and en egg-info file
use pip install, pointing at the tar.gz above to install.

Thus, it was installed successfully, as:

The package shows in /urs/local/lib/python2.7/dist-packages
The package is usable (able to import and run successfully)

The Problem

However, the problem is that I was unable to uninstall it using pip uninstall HELLOWORLD, as it shows this message Can't uninstall 'helloworld'. No files were found to uninstall.

What step do I miss?

It seems that either `pip` converts the name to lowercase either you typed it like that. It's not so good to name your Python module with all caps. — ForceBru, Sep 15 '15 at 14:17
It does. Also, I tried reinstalling with "helloworld", not "HELLOWORLD", same error. — cuongtn, Sep 16 '15 at 15:14

Found the error, it was because pip was installed via apt-get, thus outdated version.

Came to know about it since I got the same error as this: Why is PIP raising an AssertionError on pip freeze?

I had to update pip as pip install -U pip,and the problem is solved.
