I used all the modules, it all prompted NotImplementedError: Invalid CAN Bus Type - None

I tried to install the old version of the python-can module, but still can't solve my problem. Please help me answer, thank you very much. I am very anxious. Thank you!

Hello @icecolor-wiattack and sorry for the late response.

Did you find out what caused the problem in your setup?

@kasperkarlsson I had exactly the same problem. It seems that you are not configuring "interface" for python-can. To workaround it I have created .canrc file as below:

$ cat ~/.canrc [default] interface = socketcan

If anyone else is having the same problem: the need for a .canrc file is documented in the installation guide.
