After upgraded to Python 3.6 from 3.5, I encountered BeautifulSoup (bs4) error, such as 'ImportError: cannot import name 'HTMLParseError'. Seems there's compatible problem for BeautifulSoup 4 version. Solution: Upgrade beautifulsoup 4 version to 4.6.0 Commands: $ pip3 install --upgrade beautifulsoup4 Deep in: Install pip3 command: $ sudo apt install python3-pip
