Trying to run KIVY, for the first time

I'm trying to run kivy for the first time. Im using a default program.

from import App
from kivy.uix.widget import Widget

class PongGame(Widget):

class PongApp(App):
def build(self):
return PongGame()

if __name__ == '__main__':

I get this error:

done bootstraping kivy...have fun!\n
running "python.exe C:\Python27\" \n
Traceback (most recent call last):
File "C:\Python27\", line 1, in <module>
from import App
ImportError: No module named
Press any key to continue . . .

A lot of people have raised the issue online, but no one has mentioned the right solution.


UPDATE: based on the error you're getting—which you just pasted now, after my original response below—, you seem to be missing not only PyGame but Kivy itself. Go ahead and run pip install kivy.

But before you do that, I'd recommend you take a look at virtualenv and install all your Python packages specific to this project in a virtualenv created for that project. If you don't want that, you have to run sudo pip install kivy to install Kivy globally (assuming you're on OS X or Linux). On Windows, sudo should not be needed.

(Also, I'm sure the information below will be useful as well—since you don't even have Kivy, it must mean that you would have run into problems for not having PyGame either once would have installed Kivy.)


Short version:

You're missing PyGame, which is a dependency of Kivy.

Long version:

Since you didn't tell us what the error was, I went ahead and ran your code on my OS X 10.8 machine and got this:

$ python
[INFO   ] Kivy v1.7.2
[CRITICAL] [Window      ] Unable to find any valuable Window provider at all!
[CRITICAL] [App         ] Unable to get a Window, abort.

googling that error landed me on

So I went ahead and installed PyGame with the help of; except I installed it in a virtualenv:

$ pip install hg+

after that:

$ python
[INFO   ] Kivy v1.7.2
Purge log fired. Analysing...
Purge finished !
[INFO   ] [Logger      ] Record log in /Users/erik.allik/.kivy/logs/kivy_13-10-01_2.txt

[DEBUG  ] [Base        ] Create provider from mouse

And I get a nice Kivy window popping up!
