Nodriver：'NoneType'对象没有属性'close'

Question

我正在学习nodriver（版本0.37）库https://ultrafunkamsterdam.github.io/nodriver/nodriver/quickstart.html

我的行动

python3.11 -m venv venv
source venv/bin/activate
pip install nodriver

我正在尝试这个代码

import nodriver as uc

async def main():

    browser = await uc.start()
    page = await browser.get('https://www.nowsecure.nl')


if __name__ == '__main__':
    uc.loop().run_until_complete(main())

错误

python main.py

对我有用的是将 websockets 从 14.0 降低到

websockets==13.1

nodriver==0.37
