[NODRIVER] I cannot for the life of me get nodriver to run!

[tomdav999]

I cannot for the life of me get nodriver to run (Windows 10 with fresh install of python and nodriver). Very simple script. It throws an error as soon as it hits browser = await uc.start()

What am I doing wrong?

import nodriver as uc

async def main():
	print('before')
	browser = await uc.start()
	print('after')

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

Output:

py test.py
before

If anyone else has the same problem and doesn't want to waste half a day trying to figure it out, apparently you need to downgrade websockets:

pip install websockets==13.1
