Error : Unable to find valuable text provider.

[markR]

Background:

-python 3.8.10 on linux mint

-requirements file:

     certifi==2021.10.8
     charset-normalizer==2.0.12
     docutils==0.18.1
     idna==3.3
     Kivy==2.1.0
     Kivy-Garden==0.1.5
     Pygments==2.12.0
     requests==2.27.1
     urllib3==1.26.9

-created a successful install using pynsist. Had one issue where I had to change Kivy-Garden from 0.1.4 to 0.1.5 to get by a compatible wheel.

-copied to a Windows machine and extracted/installed.

-got following text provider Error-shown at bottom

-Tried to execute the fix given by StackOverflow:

Sorry,submitted inadvertently before completed.

So after the StackOverflow fix I redid all and still have the same error.

Note during execution of the fix I did get below which may be able to point me to trying something else.

HOW DO YOU LOOK FOR CORRECT VERSIONS?

Am I correct in assuming the intent is to create a self contained package of kivy app on Linux, and install on Windows?

If that is the case, its not going to work because KIvy, SDL2 and whatever are not pure Python.

[markR]

Yes you are correct. Wow, i did not think that through.

So, I know you can not cross compile but I have read that you can create an .exe by using pyinstaller on a windows machine.
Would this work for my situation?

If so, do you know references that could help me understand how to perform that? I have not found allot of detail for a beginner.

If not,  is there any way to create on linux in python utilizing packages that are not all python and having them run on Windows?

Appreciate your help.

[Robert]

I too wish I understood everything before I acted !!!!  But then there would be no debugging, and where is the fun in that?

Yes.

Elliot is the person to help you with this, here is a link to (what I understand is) his Windows pyinstaller template.

I fully expect he will answer any questions here (i know nothing)

For building Windows Apps, I use the Template Robert pointed out.  You will need to make the customizations as described.  I create a what pyinstaller calls a one-directory build, and package the app for distribution with Inno-Setup to create a professional Windows installer and uninstaller.  It has a wizard that makes it very easy to use.  https://jrsoftware.org/isinfo.php

First, Thanks Robert for adding a little much needed humor here.

Elliot,

So to back up and get my head around this, before I can start a windows build; I have a "how to get started " questions from where I am at now:

-Can I just copy my environment folder I have on linux machine to the windows machine and start from there? Or, do I have to do something like- install the same version of Python on windows machine,create an environment, move MyApp.py and other files into it, install Kivy,  create a new requirements file,etc ?

-Also I will probably need to install the deBug app (Visual Studio) I am using to make sure it runs first.

[Elliot Garbus]

You will need to begin by creating the “environment” on your Windows Machine.

Install Python, VSCode, create a Venv, pip install kivy and your other dependencies (and pyinstaller).  Copy over your program and get it running.

 

Once you have things running – and I expect that will go very quickly – you can start with pyinstaller.

I often build for Windows and Mac. I will use git/GitHub.  Under may main program directory I create a directory I typically call ProgramNameDist.  I put my spec files in that directory and pyinstaller creates its directories there.  I’ll have Innosoft Setup also create an output directory and put the exe there.

 

Pyinstaller can be challenging to debug if things do not go as expected.  Read the kivy log files for clues (usually an import has failed). 

Here is a video on what Pyinstaller does I found this helpful.  The Pyinstaller docs can get a too detailed making it difficult to understand the overall process.  The docs have plenty of good info it just hard to see the forest through the trees… https://youtu.be/tOTLqUQC-k0

 

Happy to help if you hit a snag.  Good Luck!

Good stuff! I think this is just what I need right now.

Thank you for being graciously helpful.
