新的Asyncio -我正在尝试用ccxt实现异步，并得到了这个错误

我试着在这里简单地开始，这样我就能掌握这些东西的窍门了。我理解异步的前提，但是试图与ccxt一起使用它是如此的令人费解。除了可以转发我的异步文档之外，还有推荐的资源吗？
import time
import ccxt.async_support as ccxt
import configpro
exchange = ccxt.coinbasepro({
'apiKey': configpro.apiKey,
'secret':configpro.secret,
'password': configpro.password,
'enableRateLimit': True})
async def test():
async with exchange as session:
print(await session.fetch_ticker('BTC/USD'))
async def main():
print(f"started at {time.strftime('%X')}")
await test()
print(f"finished at {time.strftime('%X')}")
asyncio.run(main())我的错误是：
Exception ignored in: <function _ProactorBasePipeTransport.__del__ at 0x000001ED6BE8EDC0>

这应该是可行的：
import time
import asyncio
import ccxt.async_support as ccxt
import configpro
print('CCXT Version:', ccxt.__version__)
async def test(exchange):
ticker = await exchange.fetch_ticker('BTC/USD')
pprint(ticker)
async def main():
exchange = ccxt.coinbasepro({
'apiKey': configpro.apiKey,
'secret':configpro.secret,
'password': configpro.password,
})
print(f"started at {time.strftime('%X')}")
await test(exchange)
print(f"finished at {time.strftime('%X')}")
await exchange.close()
asyncio.run(main())请查看这里的示例：
