attributeerror: htmlparser object has no attribute unescape

Cause of attributeerror: htmlparser object has no attribute unescape

This attributeerror: htmlparser object has no attribute unescape error occurs while installing some packages in python with the help of the pip command in the terminal. The main cause is that while writing the command we write

unescape = getattr(html, ‘unescape’, html_parser.HTMLParser().unescape)

Which returns an error stating “attributeerror: htmlparser object has no attribute unescape” because HTMLParser object has no parameter or attribute named unescape. 

The error looks like the statements as written below. 

File "/usr/lib/python3/dist-packages/setuptools/py33compat.py", line 54, in <module>
       unescape = getattr(html, 'unescape', html_parser.HTMLParser().unescape)
   AttributeError: 'HTMLParser' object has no attribute 'unescape'

Solution of error 

To solve this error it is best to upgrade not only pip but distlib and setuptools also. The main reason is that as the python version upgraded the attribute named unescape in HTMLparser is no longer in use. By upgrading these modules you are able to overcome this error positively. 

Setuptools is a group of improvements to the Python distutils that make it simpler for programmers to create and distribute Python packages, particularly those that depend on other packages. Users perceive setuptools-created and -distributed packages as being typical Python packages based on the distutils library.

pip3 install --upgrade setuptools

If the above code does not work try this also. 

The default package manager for Python is called pip. Additional packages that are not a part of the Python standard library are available for installation and management.

A library called Distlib supports low-level operations related to Python program packaging and distribution. It is meant to serve as the foundation for packaging tools made by other companies.

pip3 install --upgrade pip 
pip3 install --upgrade distlib
