Hi sonnyyu, you seem to be the Dropbox/Arduino integration expert (among other skills) and therefore I think you can help me.

I haven't been able to install the Dropbox SDK on an Arduino Yun (it is up to date)

When I run

pip install dropbox

this is what I got in return

Collecting dropbox

I have posted the question on Dropbox forum but got no useful answer. You are kind of last resource!!!

Many thanks in advance
