EXE bundled with pyinstaller fails with ImportError: No module named 'kivy.weakmethod'

[Andreas Ecker]

Kivy: 1.9.2-dev0.13012017.67b9bebd - installed from nightly wheels

Python: Python 3.4.4 (v3.4.4:737efcadf5a6, Dec 20 2015, 19:28:18) [MSC v.1600 32 bit (Intel)] on win32

OS: Windows 7 Pro Service Pack 1 64 bit

Pyinstaller: 3.2.1

The error message after running the EXE file:

Content of my pyinstaller spec file (Following the instructions on the kivy pyinstaller page: https://kivy.org/docs/guide/packaging-windows.html):

# -*- mode: python -*-
from kivy.deps import sdl2, glew


block_cipher = None


print(sdl2.dep_bins + glew.dep_bins)


a = Analysis(['SihotResImport.py'],
             pathex=['C:\\src\\python\\AcuSihotInterfaces\\SihotResImport'],
             binaries=None,
             datas=[('SihotResImport.kv', '.')],
             hiddenimports=[],
             hookspath=[],  #'C:\\Python34\\Lib\\site-packages\\kivy\\tools\\packaging\\pyinstaller_hooks'],
             #hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          *[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)],
          name='SihotResImport',
          #exclude_binaries=True,
          debug=True,
          strip=False,
          upx=True,
          console=True )

I also tried without specifying the hookspath and with/without exclude_binaries without any difference. Also a direct build without a modified spec file shows the same error.

And as you can see in the error: pyinstaller seems to find and include most of the kivy core modules but kivy.weakmethod seems to be missing.

The kivy app I want to convert into an onefile-EXE can be found on github: https://github.com/AndiEcker/AcuSihotInterfaces.

For to reproduce simply use the two attached files (or download SihotResImport.py and SihotResImport.kv from this repo) and then follow the steps given in  https://kivy.org/docs/guide/packaging-windows.html

Fighting the whole day with this problem - any pointer would be highly appreciated :)

[Andreas Ecker]

After some tweaking I think I found the problem within the pyinstaller kivy hook module (C:\Python34\Lib\site-packages\PyInstaller\hooks\hook-kivy.py). At least by hot-patching the code line

    `if is_module_satisfies('kivy >= 1.9.1'):`

into `if True:` the EXE runs without any crash/error (and the warning "Hook disabled because of Kivy version < 1.9.1" disappears from the console output on app startup).

I am using the nightly kivy wheels from last week and the newest pyinstaller (3.2.1). Unfortunately I am currently very busy with urgent tasks, so would highly appreciate if somebody could fix this upstream within pyinstaller.
