It seems like it could be related to #1883 ?

TL;DR: I think you need to update your Node to version 6.x.x.

Edit:
Yip - updating Node from v4.x.x to v6.4.0 did the trick for me.

[web-dave]

same here. working hard to fix my machine. I Need it to talk at a meetup about cli!!!!

Windows 10
Node V4.5.0
npm 3.8.7

Last command i tryed before it breaks was to install angular-cli 1.0.0-beta.11-webpack.3.

@solms Node Version greater 4 not working with node-sass!! I try to reinstall node.

[theunreal]

Upgrading to node 6 resolved this issue but remains another

[web-dave]

Reinstall node 4.5 doesn't solve the problm, intall node 6.5 doesn't solve th Problem!!

I get into Panic cause of the talk i give next week.

[web-dave]

I fixed my machine npm install -g [email protected]
ng v
angular-cli: 1.0.0-beta.11-webpack.2
node: 4.5.0
os: win32 ia32 but now no .d.ts file found

Updating node to v6 also did work for me too, but another issue has risen, as @theunreal had:

You should update your angular-cli.json file with the new version.

  "project": {
    "version": "1.0.0-beta.11-webpack.8",
    "name": "ng2-cli-webpack-8"

Change the package.json. set TypeScript Version from ^2.0.0 to 2.0.0.

This solved my Problem

AND node Version v4.5

[jminuscula]

I was having the same problem; fixed it by updating theangular-cli.json carefully as suggested by @nhenneaux. Some attributes such styles or scripts are mandatory.

@manuelxtrem check for apps[0].styles in your angular-cli.json. It's what's making the build fail.

[filipesilva]

The latest beta.14 should have fixed these issues. See https://github.com/angular/angular-cli/wiki/Upgrading-from-Beta.10-to-Beta.12 on how to update.
