Here’s my SO description.

Current behavior I upgraded Node and NPM and reinstalled Angular CLI (angular-cli: 1.0.0-beta.11-webpack.8, node: 6.5.0, os: linux x64), generated a trivial foo project which worked fine. Then I bumped Angular 2 to RC.6 and got this error:

jan@linux-zd16:~/src/fm-repos/foo> ng serve
ERROR in [default] /home/jan/src/fm-repos/foo/node_modules/@angular/forms/src/directives.d.ts:26:45 
Generic type 'Type<T>' requires 1 type argument(s).
ERROR in [default] /home/jan/src/fm-repos/foo/node_modules/@angular/forms/src/directives.d.ts:27:49 
Generic type 'Type<T>' requires 1 type argument(s).
ERROR in [default] /home/jan/src/fm-repos/foo/node_modules/@angular/forms/src/directives.d.ts:28:49 
Generic type 'Type<T>' requires 1 type argument(s).

Expected/desired behavior I’m expecting a clean build with no compilation errors.

Reproduction of the problem

nvm install 6.5
npm uninstall angular-cli
npm cache clean
npm install angular-cli@webpack
ng new foo

Validate that this trivial application works with RC.5. Then update package.json to RC.6 and router to RC.2:
