unable to import BeautifulSoup (python 3.6 and bs4-4.1.0)

Question

I have installed bs4 on my system successfully (using python setup.py install). Now the problem is while importing BeautifulSoup in python I'm getting below errors:

C:\Users\dipankar>python
Python 3.6.3 (v3.6.3:2c5fed8, Oct  3 2017, 18:11:49) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from bs4 import BeautifulSoup
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

from html.parser import (
ImportError: cannot import name 'HTMLParseError'
>>>

Answer 1

After doing a lot of google searches

pip install --upgrade beautifulsoup4

worked for me.

Answer 2

As you can read here

because HTMLParseError is deprecated from Python 3.3 onwards and removed in Python 3.5.

I will recommend you to use other parser. Check BeautifulSoup Documentation
