使用asyncio的Python中出现回溯错误

这应该只是一个简单的井字游戏，我想做的就是让打印功能正常工作。我们应该从用户那里运行它，但是所有的游戏功能都应该在服务器上运行

User.py
import sys
import asyncio


async def main():
    server = await asyncio.subprocess.create_subprocess_exec(
        "python", "Server.py", stdin=asyncio.subprocess.PIPE, stdout=asyncio.subprocess.PIPE
    )

    server.stdin.iwrite(int(0))
    board = await server.stdout.readline()
    print(board.rstrip())

    await server.wait()
    server.close()

asyncio.run(main())

AI.py现在是空的

这是我得到的错误：

我一点也不懂，我在网上找不到任何关于它的信息，所以我在这里。请帮助。

您的错误是

AttributeError:'StreamWriter'对象没有属性“iwrite”

。您试图调用

server.stdin.iwrite（int（0））

，但

server.stdin

上没有

iwrite

方法。
