beautifulsoup lxml解析器问题

import bs4
import urllib.request
import urllib.parse
import re

name=str(input('请输入搜索内容:'))
name=urllib.parse.quote(name)

head={'User-Agent':'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.98 Safari/537.36 LBBROWSER'}
req=urllib.request.Request('https://baike.baidu.com/item/{}'.format(name),headers=head)
response=urllib.request.urlopen(req)
html=response.read().decode('utf-8')

soup=bs4.BeautifulSoup(html,'lxml')
print(soup.head)

用bs4的时候一直报这个错，百度了也解决不了，有大佬能解决一下吗{:10_266:}

你安装lxml库了吗？

安装下解析器，你使用 lxml 解析器之前肯定要先安装 lxml 模块：

python -m pip install lxml -i https://pypi.tuna.tsinghua.edu.cn/simple

代码没问题，运行不报错：

用python -m pip install lxml -i https://pypi.tuna.tsinghua.edu.cn/simple安装完lxml后就行了{:10_298:}，感谢，不过我之前用 pip install lxml安装过lxml, 不知道为什么一直报错
