Hello,
I bought a new chromebook and I am trying to install kivy. I got bot pythons:
```
~$ python --version
Python 2.7.13
~$ python3 --version
Python 3.5.3
```
```
python3 -m pip install kivy
Collecting kivy

```
Is there a proper protocol to install kivy 1.11 on chromebook?
Also, since python 2 is deprecated, it should run on python 3.
I have installed pip for python 3
```
~$ python3 -m pip -V
pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.5)
```
Thank you
