Error about parser library and tree builder

[Led_Zeppelin]

I am trying to run the code shown below. It fails at the line indicated as shown in this error;

FeatureNotFound                           Traceback (most recent call last)
<ipython-input-9-42bc73e2ba3f> in <module>
----> 1 soup = BeautifulSoup(html, 'lxml')

~\miniconda3\lib\site-packages\bs4\__init__.py in __init__(self, markup, features, builder, parse_only, from_encoding, exclude_encodings, element_classes, **kwargs)
    241             builder_class = builder_registry.lookup(*features)
    242             if builder_class is None:
--> 243                 raise FeatureNotFound(
    244                     "Couldn't find a tree builder with the features you "
    245                     "requested: %s. Do you need to install a parser library?"

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

I am using beautiful soup 4.9.3 and bs4 0.0.1

I am using python 3.8.10 on Windows 10 64 bit.

The code for the program is as follows:

from bs4 import BeautifulSoup
import requests
import re
import time
import random
import sys
import numpy as np
import pandas as pd
from selenium import webdriver
import chromedriver_binary

link = 'https://finance.yahoo.com/quote/AAPL/financials?p=AAPL'

url = link

user_agent = {'User-agent': 'Mozilla/5.0'}
response  = requests.get(url, headers = user_agent)

# !pip install chromedriver-binary==79.0.3945.36

# !pip install selenium

driver = webdriver.Chrome()

driver.get(link)

html = driver.execute_script("return document.body.innerHTML;")

soup = BeautifulSoup(html, 'lxml')

There are alternative inputs for

soup = BeautifulSoup(html,'lxml')

I have tried a few and nothing works.

Please inform a to how to remove error.

Respectfuly,
