Same here, any news ?

Just got this... stopped dead in my tracks ugh! anyone have info? I was trying to upgrade from ember 1.8.1 to 1.9.1 and it was first having issues with handlebars 1.1.3 and saying use 2.0.0

Add the broccoli-ember-hbs-template-compiler package to your devDependencies.

I tried @dmathieu's suggestion and it stopped throwing the error for me but was not rendering the application template. Then I read through this announcement - http://emberjs.com/blog/2014/12/08/ember-1-9-0-released.html.
npm uninstall --save-dev broccoli-ember-hbs-template-compiler
npm install --save-dev ember-cli-htmlbars@0.6.0

fixed the problem for me.
