WebbThis is implemented by waiting on an event or condition variable until a completion handler is available in the completion event queue. Implementation Using Windows Overlapped I/O On Windows NT, 2000 and XP, Vista, 7 and later, Boost.Asio takes advantage of overlapped I/O to provide an efficient implementation of the Proactor design pattern. Webb我有完全相同的错误。我开了issue. 如果您想继续使用当前的 Python 版本,我已经找到了临时解决方案,即将以下几行添加到 asgiref\__init__.py (正如 issue 中所建议的那样): if sys.platform == "win32" and sys.version_info >= (3, 8, 0): asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
