I am currently setting up a vagrant box for starting the development of experimental node.js + angularjs app. Since I am just starting with angular, I want to give a first try to the angular-phonecat app, the one given as a tutorial by google.
I installed node in the guest machine, and the synced folder is where I cloned the angular-phonecat github repo (at the host machine but since it's synced, this shouldn't matter). In other words: all the files in the repo are present at my filesystem too.
I followed the steps mentioned at https://docs.angularjs.org/tutorial (step 0). Of course, I installed node at the guest machine.
The problem comes after the first time I run "npm install". The postinstall script is failing, so after this some dependencies are missing. I can start the server and access it from my host machine, where I see there are some 404 errors when trying to fetch jquery and other libraries from my host machine. Of course they are not there, and altough I could place them manually, this is not the way it should be.
This is the error I get
npm ERR! angular-phonecat#0.0.0 postinstall: `bower install`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the angular-phonecat#0.0.0 postinstall script.
npm ERR! This is most likely a problem with the angular-phonecat package,

If I do what the error suggests in order to track it down, I get
vagrant#precise64:/vagrant/angular-phonecat$ npm owner ls angular-phonecat
npm ERR! owner ls Couldn't get owner data angular-phonecat
npm ERR! 404 404 Not Found: angular-phonecat

So I am a bit stuck since I do not know how to interpret this second message. Any ideas? Anyone with a similar problem over there?

Already found it. I was tracking the wrong clue.
Git was not installed at the guest machine. I found this when I tried to run "bower install".
While git at the guest machine was not necessary for following the steps given at the angular-phonecat tutorial, it's used by bower to fetch the dependencies, and its absence was causing the postinstall script to fail.
