I’m currently trying to make an executable using py2exe. I use Python 3.6. The script I’m using imports openpyxl and pptx and runs fine when I use Pycharm or run the script using the command window.

The output produces the error:

IndexError: tuple index out of range

Below you can find the cmd output:

C:\Python36>python setup.py py2exe

C:\Python36>

What causes the IndexError?

Edit: here is the setup.py file:

from distutils.core import setup
import py2exe

setup(console=['Storybookmaker.py'])

Python 3.6 completely redesigned the bytecode for CPython (it’s not a “byte” code at all anymore, it’s a wordcode, where all opcodes are two bytes wide instead of 1-3).

The failure you’re seeing occurs in py2exe opcode parsing code, which, given the most recent posted version of py2exe only claims support for 3.3 and 3.4, could not possibly have knowledge of, or support for, the new wordcode opcodes; they hadn’t even been conceived of at the time py2exe was last updated. The bytecode often changes in small ways from version to version that could break even Python 3.5 (given only 3.3 and 3.4 support is claimed explicitly), but 3.6 is 100% guaranteed to fail.

Update: At this point (November 2019), it’s been over five years since the last py2exe release, and by the beginning of 2020 (when Python 2 support lapses completely), it will not run on any supported version of Python (3.4 is already out of support). I think it’s safe to say the project is abandoned; find other options, e.g. cx_Freeze or PyInstaller.

The solution I used was to use PyInstaller as an alternative because Py2Exe stopped development at python 3.4 and will not work with newer versions.

C:/>pip install pyinstaller
C:/>pyinstaller yourprogram.py

This will create a subdirectory called dist with the yourprogram.exe contained in a folder called yourprogram.

Use -F to place all generated files in one executable file.

C:/>pyinstaller -F yourprogram

Use can use -w to if you want to remove console display for GUI’s.

C:/>pyinstaller -w yourprogram.py

Putting it all togerther.

C:/>pyinstaller -w -F yourprogram.py

Python version 3.7.3.

I had same problem, as workaround I used cx_freeze. My app is based on wxPython, windows 10, python 3.6, cx_freeze 5.5.1

This is the setup file that I used and I got msi file on dist folder.

#setup.py
import sys, os
from cx_Freeze import setup, Executable

__version__ = "1.1.0"

include_files = ['logging.ini', 'config.ini', 'running.png']
excludes = ["tkinter"]
packages = ["os", "idna", "requests","json","base64","pyodbc"]

setup(
    name = "appname",
    description='App Description',
    version=__version__,
    options = {"build_exe": {
    'packages': packages,
    'include_files': include_files,
    'excludes': excludes,
    'include_msvcr': True,
}},
executables = [Executable("b2b_conn.py",base="Win32GUI")]
)`

then python setup.py bdist_msi

I’ve had success with a Python 3.6 program using the fork of py2exe at https://github.com/albertosottile/py2exe.

I tried a workaround, by installing Python 3.4.3:

C:\socket> c:\Python34\python.exe setup.py py2exe

1) enter in your script folder

2) deactivate any antivirus that you have (weird thing, know by another SO question xD)

3) call the python 3.4.3 interpreter by his absolute path, in my case, i’ve installed in:

C:\Python34

4) execute the command

C:\Python34\python.exe setup.py py2exe
