Is it possible to convert "Shiny for python" to executable file using pyinstaller?????

[HotWesley]

Because of the project, I need to convert Shiny for Python into an exe executable file.

I tried several tests, but I failed. Is this possible? I'm asking you directly because I don't have much data on the Internet.

I'd appreciate it if you could answer me.
Have a nice day :)

Shiny here being the R Shiny Python equivalent? Given that it's a webserver where the entry point is not your own code, it'll be miserable at best.

If it's a web server entry point problem, why flask possible? In the video below, he can convert the flask app into an exe file using pyinstaller.

Is it possible that the version of Shiny for python issue is still impossible?

[bwoodsend]

I never said that makes it impossible – just that it won't be easy – in the same way that freezing flask/django is technically possible but still a terrible choice.

Shiny mentioned in the question is this below.

And the test I did is on the link below.

It won't be easy, but what can I do if possible? Please give me your opinion.

Plus, what do you think is the best choice for developing desktop apps with Python? Is it PyQt?

Well sys.stderr.write(f"Error: {module_path} not found\n") is a bug in Shiny. It's assuming that a console is available which isn't true for windowed applications. There should be an if sys.stderr is not None wrapper around that offending line.

I use PyQt. I don't particularly like it. It makes more sense than tkinter. It's more Windows-friendly than GTK. I've not really tried any others.

I can't fix it because it's a bug inside shiny package... Thank you for your answer :)
