I would generate a new project and then do a diff compare of the files between the 2. ng serve works for me.

@nmongiya make sure that your global and local angular-cli versions are the same or use the npm commands with a locally installed version (you can setup a script to do builds in the local scope).

Make sure you're project is upto date with angular@2.4.1, rxjs@5.0.1 zone zone.js@0.7.4 a simple way to ensure your required packages are up to date without reinstalling everything is to remove the following directories: node_modules/zone.js, node_modules/rxjs, node_modules/@angular-cli, node_modules/angular-cli, node_modules/@ngtools. then re-issue npm install and it should install everything that's needed. If you need to make sure your cli is globally updated, npm remove -g angular-cli then npm install angular-cli@1.0.0-beta.24 will do the trick.

I think I know what this was. Seems related to #3566, and the solution is likely the same: copy over angular-cli.json from a newly generated project.

I think something broke with the defaults. Will track resolution in that other issue though.
