ImportError: No module named kivy

Question

I am new to Ubuntu and Python. Basically I installed kivy just as the website told me to do.First I built the repo

     $ sudo add-apt-repository ppa:kivy-team/kivy

Then I do the apt

     sudo apt-get install python3-kivy

Ok now I fire up Geany and follow the websites instructions to do the infamous "Hello World" then when I run in the program directory ~/Documents/Kivy for me

    python helloWorld

Here is the code for the app

import kivy
kivy.require('1.9.0')

from kivy.app import App
from kivy.uix.label import Label

class myApp(App):
    def build(self):
        return Label(text="Hello World")

if __name__ == '__main__':
    myApp().run()

I immediately get the error

    File "~/Documents/Kivy/helloWorld", line 1, in <module>
import kivy

Any clue why this is happening?

Answer 1

You said that the apt install is:

sudo apt-get install python3-kivy

That will install kivy for python3... not python 2

Instead of running:

python helloWorld

Try typing:

python3 helloWorld

Answer 2

For any noobs like myself looking to get this going on MAC OSX and totally confused, this is from the Kivy site:

"You can run any Kivy application by simply dragging the application's main file onto the Kivy.app icon."

Answer 3

After adding the ppa, you should do "sudo apt-get update" to make sure that the package is installed.

Also it is important you run it with "python3" instead of "python" which is generally the older version. kivy you downloaded is a python3 version and doesn't get imported by legacy 2.7 python.

I got it running with

python3 helloworld.py
