Как установить модуль для XML-анализа BeautifulSoup?

Question

В this answer мне сказали не использовать BeautifulSoup(xmlData, 'html.parser') для XML разобрать, но использовать BeautifulSoup(xmlData, 'xml'). Однако этот парсер не поставляется с BeautifulSoup.

Согласно одному из комментариев, я попробовал:

питон -m пип установить LXML

Но получил:

Я использую Python 3.5.2 и хотел то, что будет работать прямо из pip, смысл не нужно компилировать отдельно.

Answer 1

Вам понадобится компилятор для Windows, чтобы установить lxml через pip.

Некоторые неофициальные сборки доступны здесь: http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml

Поиск URL для правого пакета колеса, то это должно работать:

pip install http://url_to_wheel
