‘ProactorEventLoop‘ object has no attribute ‘_compute_internal_coro‘

问题

windows开发环境Pycharm通过loop.run_until_complete执行asyncio异步多线程时突然出现报错:

"AttributeError: 'ProactorEventLoop' object has no attribute '_compute_internal_coro'"

最开始怀疑时Python版本问题或者环境配置问题，排查了很久都没有解决问题。

解决步骤

在Google发现了是Pycharm升级到2023.3后导致的，只能回退版本或修改配置

• 在Pycharm使用快捷键 CTRL+Shift+A
• 输入 "Registry..."
• 修改 python.debug.asyncio.repl 取消勾选
• 重启
