萌新来问一个树莓派和Arduino之间连接的问题

Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/serial/serialposix.py", line 265, in open
self.fd = os.open(self.portstr, os.O_RDWR | os.O_NOCTTY | os.O_NONBLOCK)
FileNotFoundError: [Errno 2] No such file or directory: '/dev/ttyACM1'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/home/pi/Desktop/TEST.py", line 3, in <module>
ser = serial.Serial('/dev/ttyACM1', 9600,timeout=1); #打开端口，每一秒返回一个消息
File "/usr/lib/python3/dist-packages/serial/serialutil.py", line 236, in __init__
self.open()
File "/usr/lib/python3/dist-packages/serial/serialposix.py", line 268, in open
raise SerialException(msg.errno, "could not open port {}: {}".format(self._port, msg))
serial.serialutil.SerialException: [Errno 2] could not open port /dev/ttyACM1: [Errno 2] No such file or directory: '/dev/ttyACM1'

端口已经进行设置了，还有可能是serial端口的问题吗？

楼主解决了吗
，我也是这样的问题
