Html5lib: Typeerror: __init__() Got An Unexpected Keyword Argument 'encoding'

I'm trying to install html5lib. at first I tried to install the latest version (8 or 9 nines), but it came into conflict with my BeautifulSoup, so I decided to try older verison (0

Solution 1:

I see something was broken in the latest versions of html5lib in regard to bs4, html5lib.treebuilders._base is no longer there, usng bs4 4.4.1 the latest compatible version seems to be the one with 7 nines, once you install it as below it works fine:

 pip3 install -U html5lib=="0.9999999"

Tested using bs4 4.4.1:

In [1]: import bs4

In [2]: bs4.__version__Out[2]: '4.4.1'In [3]: import html5lib

In [4]: html5lib.__version__Out[4]: '0.9999999'In [5]: from urllib.requestimport  urlopen

In [6]: withurlopen("http://example.com/") asf:
   ...:         document = html5lib.parse(f, encoding=f.info().get_content_charset())
   ...:     

In [7]: 

You can see the change in this commit Rename treebuilders._base to .base to reflect public status the name was changed:

The error you see is because you are still using the newest version, in html5lib/_inputstream.py, HTMLBinaryInputStream has no encoding arg:

classHTMLBinaryInputStream(HTMLUnicodeInputStream):
    """Provides a unicode stream of characters to the HTMLTokenizer.

    This class takes care of character encoding and removing or replacing
    incorrect byte-sequences and also provides column and line tracking.

    """def__init__(self, source, override_encoding=None, transport_encoding=None,
                 same_origin_parent_encoding=None, likely_encoding=None,
                 default_encoding="windows-1252", useChardet=True):

Setting override_encoding=f.info().get_content_charset() should do the trick.

Also upgrading to the latest version of bs4 works fine with the latest version of html5lib:

In [16]: bs4.__version__
Out[16]: '4.5.1'

In [17]: html5lib.__version__
Out[17]: '0.999999999'

In [18]: with urlopen("http://example.com/") as f:
             document = html5lib.parse(f, override_encoding=f.info().get_content_charset())
   ....:
