Javascript RuntimeError:线程'；中没有当前事件循环；螺纹-1'；-请求\u html，html.render（）

我正在尝试使用请求HTML模块在Python中每隔10秒呈现一个HTML页面。在第一次运行时，它工作得很好，但在崩溃后，出现以下错误消息。我的部分代码是：

def get_data_from_page():
        session = HTMLSession()
        r = session.get('https://something.com/')
        threading.Timer(10.0, get_data_from_page).start()
        r.html.render()
    #code continues

def main():
    get_data_from_page()

if __name__ == '__main__':
    main()

错误消息是：

Exception in thread Thread-1:

File "/home/david/.local/lib/python3.6/site-packages/requests_html.py", line 572, in render
        self.session.browser  # Automatycally create a event loop and browser
File "/home/david/.local/lib/python3.6/site-packages/requests_html.py", line 679, in browser
self.loop = asyncio.get_event_loop()
    File "/usr/lib/python3.6/asyncio/events.py", line 694, in get_event_loop
        return get_event_loop_policy().get_event_loop()
File "/usr/lib/python3.6/asyncio/events.py", line 602, in get_event_loop
    % threading.current_thread().name)
RuntimeError: There is no current event loop in thread 'Thread-1'.

与其每次都要启动一个计时器（从而启动一个新线程），不如每10秒启动一个执行请求的线程

例如：

class RequestThread(Thread):
    def __init__(self):
        super().__init__()
        self.stop = Event()

    def run(self):
        while not self.stop.wait(10):
            session = HTMLSession()
            r = session.get('https://something.com/')
            r.html.render()   

    def stop(self):
         self.stop.set()

然而，看起来html对线程非常不友好（它使用信号等）。因此，您必须在主线程中运行它，并为您想要执行的任何其他操作创建一个线程。类似的方法似乎奏效了：

import requests_html
import time

def get_data_from_page():
    print(time.time())
    session = requests_html.HTMLSession()
    r = session.get('https://google.com')
    r.html.render()

while True:
    next_time = time.time() + 10
    get_data_from_page()

    wait_for = next_time - time.time()
    if wait_for > 0:
        time.sleep(wait_for)
