TreeBuilderForHtml5lib 'module' object has no attribute '_base'

[wengzilla]

Subject of the issue

I am unable to download the course 'build-a-computer' and am receiving this stack trace. Any ideas on how to fix? I've already upgraded all of my scripts/libraries and am not quite sure what to do next.

Traceback (most recent call last):
  File "/usr/local/bin/coursera-dl", line 7, in <module>
    from coursera.coursera_dl import main
  File "/usr/local/lib/python2.7/site-packages/coursera/coursera_dl.py", line 63, in <module>

This is an issue with upstream package html5lib: https://bugs.launchpad.net/beautifulsoup/+bug/1603299
To fix, force downgrade to an older version:

pip install --upgrade html5lib==1.0b8

Same error,

i make a downgrade

Lol xD, Now I have the error of cookies (ref: #547)

[balta2ar]

This should be fixed in 0.7.0. Besides, we don't use html5lib anymore.

Isso resolveu meu problema.
sudo pip3 install html5lib==0.9999999

@EvaldoAraujo, você está usando a última versão do coursera-dl? O que ocorre se você remover a html5lib (não lembro se outros pacotes serão removidos)...

Se você conseguir escrever em inglês, isso facilita para o resto do pessoal que mantém o programa, já que nós temos um que é colombiano, um russo e um brasileiro (eu). Mas, se você não souber, tudo bem também.

rbrito, não escrevo em inglês, outros pacotes dependem dessa lib, eu atualizei essa lib para poder usar o Spyder3 python que usa ela. flw
