Kivy-python: error while running Hello world

Question

After installing Kivy, I tried to run a Hello World app, but I get an error. I\'ve google it but cannot find satisfied answer. Here is the error:

[INFO   ] Kivy          


        

Answer 1

That error is usually due to your computer having a very poor graphics chip, or poor video card drivers. Your card and drivers must support OpenGL ES 2 for Kivy apps to work. If you are running this in a virtual machine, make sure you have turned on 3D acceleration for that VM.

Answer 2

I was getting this same error message ("Unable to get a Window, abort.") in a virtualenv installation of kivy (installed directly from GitHub) like so:

pip install hg+http://bitbucket.org/pygame/pygame
pip install Cython
pip install git+git://github.com/kivy/kivy.git 

In my case there was an previous error related to png, so I tried installing pillow in my virtualenv:

pip install pillow

And it's now working.
