Issue with latest openrov-cockpit git



I try to upgrade to the latest openrov-cockpit software. I try to make some adaptation of openrov software to use it with a Raspberry + GrovePi cap.
I was working with the openrov-cocktpit released on 08/15/2015 and all was fine with installation and all was working well.
When I try to use the latest release for the git repository, I can’t have anything in my browser (only a black window):

git clone
cd openrov-cockpit/src
npm install
cd static
npm install
(after that, I change the phamtomjs to replace it by a arm release).
cd …
node app.js

I just have a black screen in my chrome browser without any error. The same kind of install with the openrov-cockpit released on 08/15/2015 was completly functional… Any idea of the problem ?

Last clue: If I relaunch npm install in src, I’ve got the following problem (everything is ok if I have a second call to npm install in src/static):

pi@raspberrypi:~/openrov-cockpit/src$ npm install
