pyppeteer 异常 RuntimeError: There is no current event loop in thread ‘Thread-3‘.

When creating a child thread and calling pyppeteer, an error RuntimeError: There is no current event loop in thread'Thread-3' is reported.

 

 pyppeteer startup code

loop = asyncio.get_event_loop()
loop.run_until_complete(main(name, password, keyword, isGetDefaultSKU))  # 将协程加入到事件循环loop
loop.close()

 Solution

 

Change the code above to

loop1 = asyncio.new_event_loop() 
asyncio.set_event_loop(loop1)
loop = asyncio.get_event_loop()
loop.run_until_complete(main(name, password, keyword, isGetDefaultSKU))  # 将协程加入到事件循环loop
loop.close()
