runtimeerror: no running event loop 文心快码BaiduComate 当你遇到 "RuntimeError: no running event loop" 这个错误时,这通常意味着你的异步代码中尝试执行了需要事件循环的操作,但是当前没有运行中的事件循环。这种情况在使用如 asyncio 这样的异步库时很常见。以下是一些可能的解决步骤
You get the runtimeerror: no running event loop error while you are accessing asynchronous programming features, such as coroutines or the asyncio module. This exists without a running event loop. Contents About the error We use an event loop to manage and execute our asynchronous tasks. ...
self.loop = asyncio.get_running_loop() RuntimeError: no running event loop 更换了Python版本,没有报错了,但是一直在异步哪儿,后续的加载一直加载不进去

python loop = asyncio.new_event_loop() asyncio.set_event_loop(loop) 完整示例 为了确保代码在不同环境中都能正常运行,建议使用 try-except 块来处理不同的 Python 版本和环境: python import asyncio try: # 对于 Python 3.10 及以上版本 loop = asyncio.get_running_loop() except RuntimeError: # 如果...
我有一个调用 asyncio 循环的线程,但这会导致上述异常: {代码...} 这个问题: RuntimeError: There is no current event loop in thread in async + apscheduler 遇到了同样的问题,但是他们引用了我没有的调度...
asyncio.get_event_loop() 获取当前事件循环。如果当前OS线程set_event_loop()中没有设置当前事件循环并且尚未调用,那么asyncio将创建一个新的事件循环并将其设置为当前事件循环。 因为此函数具有相当复杂的行为(尤其是在使用自定义事件循环策略时),所以在协程和回调中get_running_loop()首选使用此函数get_event_loop...
DeprecationWarning: There is no current event loop 这里就是你的错误了我的是:lo = asyncio.get_event_loop() || future = asyncio.ensure_future(a) 里面的参数不用多看,格式几乎都是一样的 解决方法: 我也是查阅了许多古籍,比如《春秋》,《战国》,很失望没找到,不过我并不气馁,终于在看完最强大脑后,我...

- Drop support for Python 3.6: * This includes code cleanup for Python 3.6 compatibility. * Use `get_running_loop()` instead of `get_event_loop()`. * Use `asyncio.run()` instead of `asyncio.run_until_complete()`. Happy to open an ipdb/ipython issue if you think there's something...
