                  问题描述

                  我正在尝试在运行 Debian 的 Raspberry Pi 上使用 Python 2.6 访问串行端口.我的脚本名为 serial.py 尝试导入 pySerial:

                  I'm trying to access a serial port with Python 2.6 on my Raspberry Pi running Debian. My script named serial.py tries to import pySerial:

                  import serial
                  ser = serial.Serial('/dev/ttyAMA0', 9600)
                  ser.write("hello world!")
                  

                  由于某种原因,它拒绝建立串行连接并出现此错误:

                  For some reason it refuses to establish the serial connection with this error:

                  AttributeError: 'module' object has no attribute 'Serial'
                  

                  当我尝试在交互式 Python 解释器中键入相同的代码时,它仍然不起作用.

                  When I try to type the same code in the interactive Python interpreter it still doesn't work.

                  奇怪的是,它曾经在大约几个小时前起作用.

                  Strangely, it used to work about a couple hours ago.

                  可能是什么问题?我已经尝试修复了一段时间,再次安装 pySerial,重写我的代码,仔细检查串口等.

                  What could be the problem? I've tried to fix this for a while, installing pySerial again, rewriting my code, double-checking the serial port, etc.

                  推荐答案

                  你导入的是模块,而不是类.所以,你必须写:

                  You're importing the module, not the class. So, you must write:

                  from serial import Serial
                  

                  需要正确安装serial模块:pip install pyserial.
