问题
I'm trying to scrape headlines from medium.com by using this library called requests_html
The code I'm using works well on other's PC but not mine.
Here's what the original code looks like this:
from requests_html import HTMLSession
session = HTMLSession()
r = session.get('https://medium.com/@daranept27')
r.html.render()
x = r.html.find('a.eg.bv')
[print(elem.text) for elem in x]
It gives me pyppeteer.errors.TimeoutError: Navigation Timeout Exceeded: 8000 ms exceeded.
Here's the full error:
Traceback (most recent call last):
File "C:\Users\intel\Desktop\hackerrank.py", line 5, in <module>
r.html.render()

content, result, page = self.session.loop.run_until_complete(self._async_render(url=self.url, script=script, sleep=sleep, wait=wait, content=self.html, reload=reload, scrolldown=scrolldown, timeout=timeout, keep_page=keep_page))

File "C:\Users\intel\AppData\Local\Programs\Python\Python38\lib\site-packages\pyppeteer\page.py", line 885, in goto
raise error

I saw a comment on one of my posts and saw others' answers too to re-run it, then it will work. I don't understand why...

The error you are getting suggests that you are not getting a response from the server in a timely manner.
I ran your code on my machine (Ubuntu 18.04) successfully and got the following results:

You must check your internet connection.
Alternatively, I'd suggest you run your idle in administrator mode and re-run your code through idle.
