笔记 -- [爬虫] -- bs4 FeatureNotFound: Couldn‘t find a tree builder with the features you requested

bs4 FeatureNotFound: Couldn’t find a tree builder with the features you requested: lxml. Do you need to install a parser library?

使用了 pip install lxml 安装好了，却依旧报错

解决方法：
将：
bs4.BeautifulSoup(html, ‘lxml’)
改为
bs4.BeautifulSoup(html, ‘html.parser’)
