RuntimeError: There is no current event loop in thread [v1.3.0]

[DmitriiCM]

Hi all,

After updating to 1.3.0 I got this error:

Traceback (most recent call last): File "/usr/local/lib/python3.8/site-packages/evdev/device.py", line 159, in __del__ self.close() File "/usr/local/lib/python3.8/site-packages/evdev/device.py", line 304, in close super().close() File "/usr/local/lib/python3.8/site-packages/evdev/eventio_async.py", line 54, in close loop = asyncio.get_event_loop() File "/usr/local/lib/python3.8/asyncio/events.py", line 639, in get_event_loop raise RuntimeError('There is no current event loop in thread %r.' RuntimeError: There is no current event loop in thread 'XXXXX'.

I am not using asyncio in the project, so, please check the dependencies.

Rolling back to 1.2.0 helps.

Thanks.

I am having a similar error:

Also a similar error here on 1.3.0, fixed by rolling back to 1.2.0. Using Python3.6.9, Ubuntu 18.04.4.

Exception ignored in: <bound method InputDevice.__del__ of InputDevice('/dev/input/event0')>

Hello, I got the same error. After a bit of research I found that the following line causes the error (it was added in 1.3.0): https://github.com/gvalkov/python-evdev/blob/0cdf86adf9576ba343c97a31bd0368c889e8d494/evdev/device.py#L304

the call to super().close() will be redirected to the eventio_async.EventIO.close method even if async has not been used.

A quick fix would be to add: except RuntimeError: pass

to the close method.
