heya! I'm running a new install of ubuntu 16.04 and I have trouble setting up my dev environment. First up, if i just run sudo apt-get install npm i end up with:

➜  ~ npm -v   
3.5.2
➜  ~ node -v
v4.2.6

I'm not sure which versions of node and npm you were expecting.

i believe, since you're using the global flag (-g), you need a sudo before both npm install -g gulp and npm install -g bower.

when running npm install i got an error:

npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.0.12

However, this looks OK, because it's optional and just a WARN not a FATAL.

next up is that node can't actually be run in bower install, because it's called nodejs, so thanks to stack overflow, i had to run this:

 sudo ln -s /usr/bin/nodejs /usr/bin/node

after that bower install gives me this error

bower install
bower                     invalid-meta The "main" field cannot contain minified files

which I can not currently get past, but haven't given up! it looks like maybe one of the src files we're referencing is minified which is not desired? i only see the vendor files as being minified, but i'm kinda stabbing in the dark here being a node newb. Hopefully using non-minified version is compatible with your dev set up so it won't break it or force upgrade or some such silliness.
