AttributeError: module 'dis' has no attribute '_unpack_opargs' While Building Python 3.6 executable using CX_FREEZE

Question

I have been trying to Convert my Python 3.6 Programs into.EXE. When I build using cx_Freeze. It generates the following error. (See Log Below)

I was earlier working with Kivy Module but after the build failed repeatedly I tried it with simple Hello World Program still, It failed.

My setup file contains from cx_Freeze import setup, Executable import statement,

When I build through python setup.py build It generates this log.

F:\Python\test>python setup.py build
running build
running build_exe
Traceback (most recent call last):

F:\Python\test>

Thanks for your Help.

Answer 1

1. Open File C:\\Users\\UserName\\AppData\\Local\\Programs\\Python\\Python35-32\\lib\\site-packages\\cx_Freeze\\finder.py :

2. Change (at line 544 ) this:

   method = dis._unpack_opargs if sys.version_info[:2] >= (3, 5) \
   else self._UnpackOpArgs

to:

   method = self._UnpackOpArgs

3. Save the file and try to build again ;)
