I just download the VS Apache Cordova Tools Update 5 and I\'m running into problems with Node and NPM. I am using the default blank cordova project for testing.
Okay I had to do a combination of things to get this working.
First of all vs-tac uses edge v4 which is not compatible with node v5 so you will need to edit the vs-tac package.json file so it refers to v5 rather than v4 (it seems to work for me but your mileage may vary)
Next as Michael Braude mentioned, you will also need this;
npm -g install npm
Finally you should be able to reinstall vs-tac with this;
npm install -g "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\ApacheCordovaTools\Packages\vs-tac"
If the result of this is not an error then double check that the file vstac_installing.tmp
has been removed from your global node_modules folder (c:\users\myuser\AppData\Roaming\npm\node_modules) - I had to manually remove it on my machine.
After all that my hello world project finally runs in the emulator!
Good luck...
