PCAN API display Failed to initialize PCAN device.please help me.

call me：A PCAN channel has not been initialized yet or failed

You're aware that you call a PCAN function which does not work which has nothing to do with Qt? You should ask at a PCAN specialized forum.
And if you post code - post it as text with the proper code tags (button </>) so it's readable instead text.

@Christian-Ehrlicher Which one?I didn't understand, sorry.

i have PCANBasic.h and .lib,and my PCAN-View can work normally.Why initialization has not been successful？

@Juney
A .h or a .lib file is used at compile/link time, when you are developing your program. That has worked fine, and is not the issue. You (or your user) has a runtime error returned from CAN_Initilaize() call. You need to read about or ask PCAN people what the problem might be.

@JonB ok thanks
