Python请求\u html:给我超时错误

Question

我试图通过使用这个名为requests_html的库从medium.com中获取标题

我使用的代码在别人的电脑上运行良好，但在我的电脑上运行不好

原始代码如下所示：

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]

它给了我pyppeteer.errors.TimeoutError: Navigation Timeout Exceeded: 8000 ms exceeded.

以下是全部错误：

Traceback (most recent call last):

  File "C:\Users\intel\Desktop\hackerrank.py", line 5, in <module>
    r.html.render()
  File "C:\Users\intel\AppData\Local\Programs\Python\Python38\lib\site-packages\requests_html.py", line 598, in 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

我在我的一篇帖子上看到了一条评论，也看到了其他人的答案，所以重新运行它，然后它就会起作用。我不明白为什么

你必须检查你的互联网连接

或者，我建议您在管理员模式下运行idle，并通过idle重新运行代码
