bs4.FeatureNotFound: Couldn't find a tree builder with the features you requested: lxml. Do you need to install a parser library?
reubano commented 7 years ago

solved with pip install --user lxml... but, that shouldn't be needed.

By default, BS4 will use the HTML parser included in Python's standard library, but it also supports third-party Python parsers, such as lxml parser and html5lib parser. In order to use the third-party Python parsers, you need to install them, since they are not the built-in part of your installation. You can find more details on the bs4 document listed below. https://www.crummy.com/software/BeautifulSoup/bs4/doc/#installing-a-parser
