Pyserial: could not configure port: (5, 'Input/output error)
提问by Donagh
I've been trying to get the following two lines of Python code to run for the past two days, without much success:
在过去的两天里，我一直试图让以下两行 Python 代码运行，但没有取得多大成功：
import serial
ser = serial.Serial(0)
Each time I run it, I get the following error:
每次运行它时，都会出现以下错误：
Traceback (most recent call last):
File "./test.py", line 4, in <module>
ser = serial.Serial(0)
File "/usr/lib/python2.7/dist-packages/serial/serialutil.py", line 260, in __init__
self.open()
File "/usr/lib/python2.7/dist-packages/serial/serialposix.py", line 280, in open
self._reconfigurePort()
File "/usr/lib/python2.7/dist-packages/serial/serialposix.py", line 308, in _reconfigurePort
raise SerialException("Could not configure port: %s" % msg)
serial.serialutil.SerialException: Could not configure port: (5, 'Input/output error')
I'm running Ubuntu 11.10 64-bit, with Pyserial 2.5 (python-serial 2.5-2.1) and Python 2.7 (python 2.7.2-7ubuntu2) and my user is a member of the dialout group.
我正在运行 Ubuntu 11.10 64 位，使用 Pyserial 2.5（python-serial 2.5-2.1）和 Python 2.7（python 2.7.2-7ubuntu2），我的用户是 dialout 组的成员。
I run Ubuntu 11.10 64-bit at work too, with the same versions of Python and Pyserial, and the problem doesn't seem to occur there. Any suggestions are welcome - I'm pretty flummoxed...
我在工作时也运行 Ubuntu 11.10 64 位，使用相同版本的 Python 和 Pyserial，问题似乎没有发生在那里。欢迎任何建议 - 我很困惑......
Thanks, Donagh

This exception is thrown if the port is not available. On Linux, you can simply specify the exact name of the port to use, like
如果端口不可用，则抛出此异常。在 Linux 上，您可以简单地指定要使用的端口的确切名称，例如
ser = serial.Serial('/dev/ttyACM0')
