Blank dashboard

Hi... I've just installed Loomio locally on an Ubuntu machine and everything seems to work fine. I can create a new user and log-in through the browser on localhost:3000
However, as soon as I log in, I'm redirected to localhost:3000/dashboard, but the screen is just completely blank. Is this a known issue? And does anyone possibly know what could be the problem?
It's running on Ubuntu 15.04 and I'm using Firefox 44.0 to access the local install of Loomio (I tried to run Firefox in Safe mode, but it didn't make any difference). I followed everything in the Tech Manual of how to set up a development environment except I installed rbenv ver 2.3.0 in stead of 2.2.1 which the manual described since this was required by some files in the Loomio repository.
I would have attached a screen shot, but there is literally nothing to see. The whole browser window is just blank.
Thanks for any help. - Nikolai

Thanks Markus. I tried to do that now. I even tried to start all over, not following the tech manual, but just cloning the git repository and run the two rake commands, but I still get exactly the same problem (the same error as the guy in the thread you linked to).
So I tried to follow your advice in the other thread on how to build the Angular app, but when I run npm install
in the angular directory I get the following error:

I tried to read the nodejs readme file that is mentioned after the first error, but I'm not very familiar with node so I can't really figure out what the problem is.

Markus Koller Fri 26 Feb 2016 8:14PM
You might be missing the nodejs-dev
package, otherwise try upgrading to a more recent NodeJS version, or switching to the official NodeSource packages.
James Kiesel Fri 26 Feb 2016 8:49PM
We're currently on Node 4.2.6; I'd recommend grabbing a copy of Node version manager and running nvm install 4.2.6
, nvm use 4.2.6
Check to make sure that running node -v
pops up v4.2.6 as well.
(Loomio's explicitly broken on 3.0 and 5.0 versions of node, although we'll likely make the leap to 5.0 at some point.)
I'll also put an entry in our package.json file in the engines field which will make this more obvious. :)
Thanks for giving this a go!

Nikolai Gad Sat 27 Feb 2016 5:12PM
Thanks a lot, that worked. Updated to node 4.2.6 and then build the Angular app as described in the other thread. Rake didn't do that automatically though.
@jameskiesel Well, thanks for developing and making this interesting software available!
Markus Koller · Fri 26 Feb 2016 3:18PM
You have to build the Angular app, try running
rake bootstrap
and thenrake bootstrap:run
which should do that for you. Also see this thread for more details, and check your browser console for errors.
