Ng new gives dryRunSink. (...). concat is not an error function

Question

I am trying to create a new angular project. I followed the steps mentioned on this site. https://github.com/angular/angular-cli

When I try to create a new project using the command ng new, I get an error.

E:\Code\> ng new some-name
Error: dryRunSink.commit(...).ignoreElements(...).concat is not a function
dryRunSink.commit(...).ignoreElements(...).concat is not a function

Here is the result ng serve

Angular CLI: 1.6.4
Node: 6.11.4

Edit: It looks like everyone is getting this error. https://github.com/angular/angular-cli/issues/9194

@ angular/cli: 1.6.5, , , :

npm uninstall @angular/cli

be sure to install dev so you can run things like npm start (ng serve) and run your project by setting:

npm install --save-dev @angular/cli@latest

Worked great for me.
