Ubuntu wacky error on kivy import

[Alan Etkin]

Hi everyone

I'm starting to test kivy, I'm a complete beginner. When I try to import kivy on a Python Interpreter it logs this

(kivy_venv) alan@alan-MS-7721:~/kivy_venv/lib/python3.12$ python
Python 3.12.3 (main, Feb  4 2025, 14:48:35) [GCC 13.3.0] on linux

>>> import kivy

OS: Ubuntu 24.04.2 LTS

I think I installed precompiled wheels with this instructions https://kivy.org/doc/stable/gettingstarted/installation.html#pre-compiled-wheels

There is no reference on the web about this issue. Any help apreciated

You can't run kivy from the REPL.   Open a file write your code, then execute the code.

[Alan Etkin]

Thank you! Executed the pong example and it worked. What is the reason you can't pass code to the interpreter?

There is a difference between the REPL and the interpreter.  

The REPL is for executing code line by line.  Kivy, at its core has an event loop.  The event loop is what runs when you call App.run().  The loop is waiting for events and then calling into your code.   The REPL does not allow the loop to run.

The event loop is described here: https://kivy.org/doc/stable/guide/events.html
