Very new on using ember (and a js framework in general) i'm following the official guide on the ember site, installed the ember-cli and create a test app but when i 'server' it a get this message:

Missing template processor

I could not find easy enough info for a beginner and i'm just stuck.

Some info about my environment on windows 7:

$ ember --version
version: 0.2.3
node: 0.12.0
npm: 2.7.6

I case anyone else is getting the same error when trying "ember server" command and the solution above doesn't work (didn't work for me). I realized I had to run:

npm install
bower install

before running the server; after doing this I was able to run "ember server" and worked good.

ember-cli projects can be finicky about its module versions. Try to update your package caches and reinstall ember-cli:

bower cache clean && npm cache clean && npm install -g ember-cli
