Solution 1 :

change your render with arender and session with asession

response = await asession.get(url)
# executando Java-script
await response.html.arender(sleep=1)

Problem :

I’m trying to do a webscraping on youtube to get the information from a video, however it is giving an error and it seems that it is in the renders () of requests_html, code below:

from requests_html import AsyncHTMLSession
import pyppdf.patch_pyppeteer
import pyppeteer

import asyncio
if asyncio.get_event_loop().is_running(): # Only patch if needed (i.e. running in Notebook, Spyder, etc)
    import nest_asyncio
url = ""

session = AsyncHTMLSession()
# inserindo a query e o numero da pagina na url
# enviado requisição para o youtube
response = await session.get(url)
# executando Java-script
await response.html.render(sleep=1)
# renomear o arquivo
link_name ='v=(.*)', link).group(1)
# Salvando arquivo HTML na pasta dados_brutos
with open("./dados_brutos/videos/video_{}.html".format(link_name), 'w+', encoding='utf8') as output:
