Can confirm this, here are the steps to replicate this issue:

1. Create angular-cli project beta 10
2. Update angular-cli to latest webpack following:
   https://github.com/angular/angular-cli/blob/master/WEBPACK_UPDATE.md
3. use the following command in terminal:
   ng set defaults.styleExt scss

Well I have been using angular cli for about two months working on a large
app with lots of different libraries installed. So my problem could be to
do with upgrading as well. I did follow the guide :)

I received the same exact error with 'ng set defaults.styleExt less' after upgrading my app this morning.

angular-cli@1.0.0-beta.11-webpack.8 is what was installed with the update.

[neojack647]

$ ng --version
angular-cli: 1.0.0-beta.11-webpack.8
node: 5.7.1
os: win32 ia32
$ node --version
v5.7.1

Same issue as #1905

[borntodesign]

I did get it to work manually by setting the default style extension to scss in angular-cli.json. I also had to restart the server.

[dessalines]

What's that line look like in angular-cli.json, to use scss?
