Pyserial：“模块‘serial’没有‘tools’属性”

Question

I have some Devices connected to my Notebook via a RS485 to USB Converter and want to detect them in a python programm.

I'm running this Code with PyCharm Community Edition on a Windows 7 Notebook , I've installed pyserial with pip.

import serial

x = list(serial.tools.list_ports.comports())
print(x)

And got this error:

Traceback (most recent call last): File "C:/Users/rzzrgx/.PyCharmCE2018.3/config/scratches/scratch_1.py", line 3, in x = list(serial.tools.list_ports.comports()) AttributeError: module 'serial' has no attribute 'tools'

Answer 1

Wrong way to import , correct it like below:

from serial.tools import list_ports

x = list(list_ports.comports())
print(x)

or

import serial.tools.list_ports

plist = list(serial.tools.list_ports.comports())
print(plist)

Answer 2

安装 pyserial（而不是串行）为我解决了这个问题
