'module' Object Has No Attribute 'to_bytes' Python

Please advise how I can cx-freeze my python program which uses serial : import serial import serial.tools.list_ports; print serial.tools.list_ports() Here's my se

Solution 1:

import sys
from cx_Freeze import setup, Executable
path = ["pystest"]+sys.path

build_exe_options = {"packages": ["os","serial"], "excludes": ["tkinter"],"path":path}
#add more package what are using for your app?

base = Noneif sys.platform == "win32":
    base = "Win32GUI"

setup(  name = "My test program",
        version = "3.1",
        description = "My test",
        options = {"build_exe": build_exe_options},
        executables = [Executable("pystest.py", base=base)])

Solution 2:

I actually ended up doing this :

1. Modfying the file list_ports_windows.py inside C:\Python27\Lib\site-packages\serial\tools and changed serial to serialutil like this :

Ports = serialutil.to_bytes([80, 111, 114, 116, 115]) # "Ports"PortName = serialutil.to_bytes([80, 111, 114, 116, 78, 97, 109, 101]) # "PortName"

2. Then Added from serial import serialutil to the imports

Not sure if this is the right or wrong way but then it worked.

Thanks.

Solution 3:

Ports = serial.to_bytes([80, 111, 114, 116, 115]) # "Ports" no attribute 'to_bytes' two step:

1、pip install pyserial==3.4

2、pip install pyserial==2.7

i don't know the reason, but it worked
