Basic code error in Kivy(Python)

Question

I made a very simple code using Kivy, but give this error that shows in the image below: The code is as follows::

import kivy
kivy.require('1.0.6')

from kivy.app import App
from kivy.uix.button import Button

class MyApp(App):
    def build(self):
        return Button(text='Hello World')

if __name__ in ('__android__', '__main__'):
    MyApp().run()

Could you explain to me what’s wrong?

Answer 1

On the official website of the Kivy library (https://kivy.org/) you can see an example of usage. The library is already in version 1.10.0.

The following example comes straight from the official website and will display a "Hello World":

from kivy.app import App
from kivy.uix.button import Button

class MyApp(App):
   def build(self):
      return Button(text = 'Hello World')

MyApp().run()

As you can see it’s very similar to your code!

Answer 2

I know the question is a few months old, but if anyone is looking for the answer, it’s here.

Some Kivy features require the installation of dependencies, so that these functionalities can work properly. These dependencies are not installed automatically so as not to impair the performance of the application by installing unnecessary things for your project, so they are taken apart.

In the Installation Guide you have the explanation for what you need: https://kivy.org/doc/stable/installation/installation-windows.html

But only by running these two command lines can you get the main dependencies:

pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew 
pip install kivy.deps.gstreamer
