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):

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 ;)
