PyFirmata2 Arduino PermissionError(13, 权限错误) (Python3)

Question

这是一个使用Arduino的汽车线圈制造商，我正在使用PyFirmata2制作它（我不使用C++因为C++对我来说有点难），然后出现一些错误，我无法修复它:

Traceback (most recent call last):
  File "c:\Users\user\Desktop\Knob\py.py", line 9, in <module>
    board = Arduino('COM4')
  File "C:\Users\user\AppData\Local\Programs\Python\Python310\lib\site-packages\pyfirmata2\__init__.py", line 13, in __init__
    super(Arduino, self).__init__(*args, **kwargs)
  File "C:\Users\user\AppData\Local\Programs\Python\Python310\lib\site-packages\pyfirmata2\pyfirmata2.py", line 119, in __init__
    self.sp = serial.Serial(port, baudrate, timeout=timeout)
  File "C:\Users\user\AppData\Local\Programs\Python\Python310\lib\site-packages\serial\serialwin32.py", line 33, in __init__

    self.open()

    raise SerialException("could not open port {!r}: {!r}".format(self.portstr, ctypes.WinError()))
serial.serialutil.SerialException: could not open port 'COM4': PermissionError(13, '存取被拒。', None, 5)

我尝试重新启动我的电脑，运行作为管理员和 NT AUTHORITY\SYSTEM，我也运行其他计算机上的代码，仍然相同 error.Heres 我的代码如下：

from pyfirmata2 import Arduino
import multiprocessing
import time
tmp = None
tmp2 = None
tmp3 = None
i = 0
port = 'COM4'
board = Arduino('COM4')
mycircle = float(input('How many circle you want?'))
carg = float(input('Coil arg?'))
rpm = float(input('Motor rpm?'))
print('start!')
def a0():
    board.digital[2].write(1)
    board.digital[3].write(0)
    board.digital[4].write(0)
    board.digital[5].write(0)
def a1():
    board.digital[2].write(0)
    board.digital[3].write(1)
    board.digital[4].write(0)
    board.digital[5].write(0)
def b0():
    board.digital[2].write(0)
    board.digital[3].write(0)
    board.digital[4].write(1)
    board.digital[5].write(0)
def b1():
    board.digital[2].write(0)
    board.digital[3].write(0)
    board.digital[4].write(0)
    board.digital[5].write(1)
def motor():
    global i
    print('start21')
    while True:
        for e in range(0,round(30/carg)):
            a0()
            time.sleep(tmp3)
            a1()
            time.sleep(tmp3)
            b0()
            time.sleep(tmp3)
            b1()
            time.sleep(tmp3)
            print(i)
            i = i+1
        e = 0
        for e in range(0,round(30/carg)):
            b1()
            time.sleep(tmp3)
            b0()
            time.sleep(tmp3)
            a1()
            time.sleep(tmp3)
            a0()
            time.sleep(tmp3)
            print(i)
            i = i+1
        e = 0
tmp = 60/rpm
tmp2 = 40*carg
tmp3 = tmp/tmp2
print(tmp3)
p=multiprocessing.Process(target=motor)
p.start()
board.digital[10].write(1)
while True:
    if i == mycircle:
        c = 1
        print('complate')
        p.terminate()
        board.digital[10].write(0)
        break
    else:
        pass

（我知道它 kinda/very 很乱，因为它是原型）
