hottowel undefined is not a function

This is my first experience using Node.js

I am following this tutorial: http://www.johnpapa.net/get-up-and-running-with-node-and-visual-studio/

I am using Cmder as my command prompt.

I have all components installed and I can view the versions of: Node npm bower yeoman gulp grunt

When I try to build the app using: gulp serve-dev --sync This is the output:

F:\Projects\myapp
λ gulp serve-dev --sync

Any idea where I'm going wrong?

I experienced the same issue. Changing the versions of devDependencies in package.json file helped. Set the versions like this:

"gulp-less": "^3.0.0",

and

"gulp-ng-annotate": "^0.5.2",

And run npm update

There was a problem with the gulp-less build. https://github.com/plus3network/gulp-less/issues/140
