How to package a Python app?

1

I could really use some help getting my Python/QT5 based app packaged as a flatpak. I have managed to get it to work if I first package it with Pyinstaller then Flatpak that, now I’m trying to package it as the actual Github release for eventual upload onto Flathub.

This is what I have so far.

I’m trying to build this with the following command:

flatpak-builder --force-clean --user build-dir io.github.riftr.intelpy.yml

I’m getting an error saying that it can’t find pip, but pip is most definitely installed on my system and nothing I’ve tried resolves it. I’ve been at this for a few hours and tearing my hair out so any help is appreciated.

Why do you have com.riverbankcomputing.PyQt.BaseApp commented out? Also, PIP installed on your system doesn’t matter - build is inside the container

3

It’s commented out because with it I get the error “Failed to init: Unable to find app com.riverbankcomputing.PyQt.BaseApp version master”

How do I get pip inside the container?

Define base-version as well. AFAIK pip is provided by that baseapp

Okay I feel like we’re hopefully on the right track but no luck yet.

I’ve got in the yml file:

base: com.riverbankcomputing.PyQt.BaseApp
base-version: "5.15-23.08"

I’ve also installed it using:

flatpak install flathub com.riverbankcomputing.PyQt.BaseApp//5.15-23.08

But sadly still getting the error that pip is not found. Even changing “pip3” to “pip” in the file doesn’t matter.

Output:

$ flatpak-builder --force-clean --user build-dir io.github.riftr.intelpy.yml

This might be incorrect: --env=PYTHONPATH=/app/site-packages. Also, did you generate your dependency list using flatpak pip generator or manually?

I got a little further by changing the sdk: line to sdk: org.kde.Sdk and installing the matching SDK from flathub. It’s seeing pip now (yay!) but now it’s unhappy about the PyQt5 version (I’m using the latest on PyPI 5.15.10)

I have manually created the dependency list based on what my app normally uses.

PyQt5 is in the base runtime. No need to install it yourself
