bs4解析网页时报错:bs4.FeatureNotFound: Couldn't find a tree builder with the features you requested: html_parser. Do you need to install a parser library?
原因:不可以使用 BeautifulSoup(html,'html_parser')
解决办法:
1.安装 pip install lxml
2.将BeautifulSoup(html,'html_parser') 改为BeautifulSoup(html,'lxml')
另:好像有人遇到的情况和我的正好相反,由于刚开始接触python,还不是很了解具体原因,希望后期能够了解具体的原因。
