Python调用playsound时报错：指定的设备未打开,或不被 MCI 所识别

报错信息：

Error 263 for command:

close audio.mp3

指定的设备未打开,或不被 MCI 所识别。

原因：

windows不支持utf-16编码，需修改playsound源码

playsound在：C:\Users\Megan\AppData\Local\Programs\Python\Python37\Lib\site-packages\playsound.py

解决：替换这个函数即可

def winCommand(*command):
        bufLen = 600
        buf = c_buffer(bufLen)
        #command = ' '.join(command).encode('utf-16') # 1.修改前
        command = ' '.join(command) # 1.修改后
        errorCode = int(windll.winmm.mciSendStringW(command, buf, bufLen - 1, 0))  # use widestring version of the function
        if errorCode:
            errorBuffer = c_buffer(bufLen)
            windll.winmm.mciGetErrorStringW(errorCode, errorBuffer, bufLen - 1)  # use widestring version of the function
            exceptionMessage = ('\n    Error ' + str(errorCode) + ' for command:'
                                #'\n        ' + command.decode('utf-16') + # 2.修改前
                                '\n        ' + command + # 2.修改后
                                '\n    ' + errorBuffer.raw.decode('utf-16').rstrip('\0'))
            logger.error(exceptionMessage)
            raise PlaysoundException(exceptionMessage)
        return buf.value
