Python：“无法关闭正在运行的事件循环”Asyncio

Question

import asyncio
import Twper

async def main():
    q = Query('Some Query Goes Here', limit=20)
    async for tw in q.get_tweets():
        # Process data
        print(tw)


loop = asyncio.get_event_loop()
try:
    loop.run_until_complete(main())
    loop.run_until_complete(loop.shutdown_asyncgens())
finally:
    loop.close()

When I run it, I get the message:

File "C:\\Users\\Anaconda3\\lib\\asyncio\\selector_events.py", line 94, in close raise RuntimeError("Cannot close a running event loop")

What can I do, to use Twper properly and scrape tweets?

Answer 1

You cannot close a running loop without stopping it first. Try doing:

loop.stop()
time.sleep(1)
loop.close()
