尝试运行docs中给出的asyncio hello world代码示例时:

import asyncio

async def hello_world():
    print("Hello World!")

loop = asyncio.get_event_loop()
# Blocking call which returns when the hello_world() coroutine is done
loop.run_until_complete(hello_world())
loop.close()

我收到错误:

RuntimeError: Event loop is closed

我使用的是python 3.5.3.
