Angular2 - sass unable to build on angular-cli

Question!

I'm trying to use SASS with angular-cli. I've read the docs and found other SO q/a's that talk about setting it up...but it keeps failing the build.

Here's my setup:

angular-cli-build.js

sassCompiler: {
  includePaths: ['src/app/styles']
}

src/app/styles/master.scss

@import 'folder/variables';
@import 'folder/headers';

src/app/styles/folder/_variables.scss

$headers-bg: #ababab;

src/app/styles/folder/_headers.scss

h1 {
  background-color: $headers-bg;
}

package.json (per request)

{
  "name": "my-app",
  "version": "0.0.0",
  "license": "MIT",
  "angular-cli": {},
  "scripts": {
    "start": "ng server",
    "postinstall": "typings install",
    "lint": "tslint \"src/**/*.ts\"",
    "test": "ng test",
    "pree2e": "webdriver-manager update",
    "e2e": "protractor"
  },
  "private": true,
  "dependencies": {
    "@angular/common": "2.0.0-rc.1",
    "@angular/compiler": "2.0.0-rc.1",
    "@angular/core": "2.0.0-rc.1",
    "@angular/http": "2.0.0-rc.1",
    "@angular/platform-browser": "2.0.0-rc.1",
    "@angular/platform-browser-dynamic": "2.0.0-rc.1",
    "@angular/router": "2.0.0-rc.1",
    "es6-shim": "^0.35.0",
    "reflect-metadata": "0.1.3",
    "rxjs": "5.0.0-beta.6",
    "systemjs": "0.19.26",
    "zone.js": "^0.6.12"
  },
  "devDependencies": {
    "angular-cli": "^1.0.0-beta.5",
    "codelyzer": "0.0.19",
    "ember-cli-inject-live-reload": "^1.4.0",
    "jasmine-core": "^2.4.1",
    "jasmine-spec-reporter": "^2.4.0",
    "karma": "^0.13.15",
    "karma-chrome-launcher": "^0.2.3",
    "karma-jasmine": "^0.3.8",
    "node-sass": "^3.7.0",
    "protractor": "^3.3.0",
    "ts-node": "^0.5.5",
    "tslint": "^3.6.0",
    "typescript": "^1.8.10",
    "typings": "^0.8.1"
  }
}

Unfortunately, the build fails because it doesn't know what $bg is.

Build failed.
File: /my-app/tmp/sassplugin-input_base_path-jFTXlfed.tmp/0/
src/app/styles/folder/_more.scss (2)
The Broccoli Plugin: [SASSPlugin] failed with:
Error: Undefined variable: "$headers-bg".

What am I missing? Its as if the compiler isn't respecting the normal behavior of ignoring the "_"'d file names.

Answers

You have things a little backwards as you're importing in a style and not importing your variable... see this example as a guide...

define your variables:

_variables.scss

$bg: #ababab;

use them: site.scss

@import '_variables';
body {
  background: $bg;
}

After reading through the source code, I found this 17 day old commit.

I was right in my initial hunch that it wasn't ignoring partials. Basically, you have to tell the sassCompiler that you want it to ignore them.

Here's how:

sassCompiler: {
  cacheExclude: [/\/_[^\/]+$/]
}
