• Eu também tentei com o cython 0.25.2

Answer 1

Ok, agora eu percebi esse problema. Isto é por causa da instalação de pacotes de cache pip eu tive pacotes quebrados cython e kivy no cache devido a isso toda vez que em vez de baixar um novo pip usa cache que já quebrou. E agora como esses pacotes quebraram por causa da troca da versão padrão do python sudo update-alternatives --config python3 aqui eu tinha setado o python3.6 default e baixei todos os pacotes mas algum trabalho interno do ubuntu (não sei) não suportam o python3.6 ele suporta python3 .5 devido a este download pacotes currept e vai para o cache e quando eu mudar para python3.5 ubuntu funciona muito bem, mas os pacotes tinham quebrado.

    

Answer 2

Em vez de pip tente apt:

 sudo add-apt-repository ppa:kivy-team/kivy
 sudo apt-get update
 sudo apt-get install python-kivy # or python3-kivy if you're using python3

    

Answer 3

Tente instalar pip install cython==0.25.0 e, em seguida, instale todos os requisitos de Kivy official install intructions .

It's possible that you can use newer version of cython, but last time when I tried with cython 0.26 and kivy 1.10 I had to downgrade cython.
