如何安裝BeautifulSoup XML解析模塊？

Question

在this answer，我被告知不使用BeautifulSoup(xmlData, 'html.parser')解析XML，但使用BeautifulSoup(xmlData, 'xml')。但是，該解析器不會附帶BeautifulSoup。

按照一個評論，我想：

蟒蛇-m PIP安裝LXML

不過的了：

我使用Python 3.5.2並想有些東西可以正確使用pip，這意味着不需要單獨編譯。

Answer 1

您需要Windows上的編譯器才能通過pip安裝lxml。

一些非官方版本是可在這裏：http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml

的右輪包查找網址，然後這應該工作：

pip install http://url_to_wheel
