Attribute error on #:import in kv file

[WvdB63]

I have a Python 3.9 / Kivy 2.0.0 app running perfectly well on Windows10 within PyCharm. 

When building the exe using PyInstaller (4.5.1) the app builds, the exe starts but crashes at a certain point.

The exception is: 

  File "appguides.py", line 72, in <module>

  File "kivy\lang\builder.py", line 373, in load_string

  File "kivy\lang\parser.py", line 402, in __init__

  File "kivy\lang\parser.py", line 508, in parse

  File "kivy\lang\parser.py", line 477, in execute_directives

AttributeError: module 'pmuix' has no attribute 'data_table'

At line 72 in appguides.py I have:

from appguideskv import style, APPGVersionItem
Builder.load_string(style)

and in appguideskv I have the following import statements:

#:import Factory kivy.factory.Factory
#:import dp kivy.metrics.dp
#:import PMDataTable pmuix.data_table
#:import PMTextField pmuix.textfields
#:import PMIconButton pmuix.iconbutton

The project structure is as follows:

myapp

    > folder: pmuix

           file: __init__.py

           file: data_table.py

           file: textfields.py

           file: iconbutoon.py

Obviously the #:import statement is not handled correctly by PyInstaller (?) or .....?

Who can help me out here? I am stuck ....

Pyinstaller does not understand kv, and so does not see the kv import statements.

You can add the import statements to the hidden imports section of your spec file or in your main python file import those modules.

I prefer to do the imports in the main python module, and have a spec file I can generally reuse with minimal customization.

 

Pycharm will let you know that the imported modules are not being used, just ignore that.

Here is the spec file I use for creating apps.  I create a directory at the same level as the source code under a project, call ProjectDist.  I mention this because I use relative paths to identify files.

This will build a ‘one folder bundle’  I package the exe and the directory using https://jrsoftware.org/isinfo.php  This creates a professional looking installer that also generates an uninstaller in Windows.

 

# -*- mode: python -*-


import os
from kivy_deps import sdl2, glew

spec_root = os.path.abspath(SPECPATH)
block_cipher = None
app_name = 'Your App Name'
win_icon = '../Images/your_icon.ico'

a = Analysis(['../main.py'],
             pathex=[spec_root],
             binaries=[],
             datas=[('../*.kv', '.'),                   # Change these to match your project
                    ('../Images/*.png', './Images')],
