I’m receiving this error as well after starting a new project based off of the tutorial (i.e. ionic start MyIonicTutorial tutorial --v2.

I was able to comment out the same code to get this passing like the post above, but then I get another one:

node_modules/ionic-angular/components/tabs/tabs.wp.scss
Error: Undefined variable: "$color-contrast".
        on line 88 of node_modules/ionic-angular/components/tabs/tabs.wp.scss
>>       color: $color-contrast;

At this point the project does get served up, but the styles are not correct because all of the scss files are not compiling successfully.

Ionic Info:

Cordova CLI: 6.1.1
Ionic Framework Version: 2.0.0-beta.4
Ionic CLI Version: 2.0.0-beta.25
Ionic App Lib Version: 2.0.0-beta.15
ios-deploy version: 1.8.6
ios-sim version: 5.0.8
OS: Mac OS X El Capitan
Node Version: v5.10.1
Xcode version: Xcode 7.3 Build version 7D175

Any help would be appreciated. The github repo for the tutorial does not have issues enabled, so I cannot file one there. Let me know if I need to file this as an issue in the core ionic repo.

If u still have problem:

Install new ionic 2 version with: ionic start … --v2
Copy your “app” folder into this new one.

Profit :slight_smile:

After that output the same problem?

There’s already an open issue about this (there’s also a workaround in the comments):
