Kivy: Unable to run kivy on raspberry pi with

[shifters67]

HI all,

i get the following when trying trying to run kivy on the raspberry pi with a texy 2.8" colour lcd with touch screen. I have followed the instructions http://kivy.org/docs/installation/installation-rpi.html exactly and all seem to build ok with no errors.

I have tried the dev build and the global build options.

I have tried running from the shell command line and from an xterm in X - same error.

Any ideas? This is raspbian latest everything with texy ammendments found here http://www.raspberrypi.org/forums/viewtopic.php?f=45&t=64993 for the touch screen.

The Showcase application requires 2 packages more than just Kivy. You are
missing pyglet (Lexer) and probably also docutils. You can install them
with:
sudo pip install pyglet docutils

Many thanks brousch for the quick response.

I have tried the above but still get the same error message. Any ideas?

Tried loading the pictures demo - no error there but also no display either on the mini screen instead it goes to the big screen but at least it works!

I have raised an issue with texy the creator to see if this is a driver issue

It needs pygments, not pyglet :) It was a typo of brousch. Kivy itself doesn't require it, except if you use the CodeInput widget. Same for docutils, it is required by the RstDocument widget.

Thanks.

To get it to work:

buildozer.spec:

requirements = kivy,pil,sqlite3,pygments,docutils

[aleksandaratanasov]

Shouldn't this dependency be actually listed as such? I find it rather annoying that following the official guide on installing Kivy on the RPi you have to dig into the issues on GitHub to find a solution for this problem. After all the demos should be the ones that run without any issues WITH the things that are listed as requirements to get Kivy installed on the system. Please consider adding at least a warning if the required packages for the showcase are not met.
