如何使一個webpack，Angular2和SASS項目的業力工作？

Question

我使用angular2-webpack-starter，我的樣式表爲SASS。一切都可以正常使用，但是當我嘗試運行業力測試中，它無法給我這個錯誤

ERROR in ./src/app/widgets/message/messages.scss 
Module parse failed: d:\ui_widgets-A2\src\app\widgets\message\messages.scss Unexpected token (6:22) 
You may need an appropriate loader to handle this file type.

我試圖安裝karma-sass-preprocessor和karma-scss-preprocessor，但似乎沒有任何工作。我該怎麼辦？

Answer 1

因此，答案是很瑣碎，我在webpack.common.js有

{ 
    test: /\.scss$/, 
    exclude: /node_modules/, 
    loaders: ['raw-loader', 'sass-loader'] 
    } 

由於某種原因，我認爲webpack.test.js也得到它，但事實證明，我應該也已經將它添加到webpack.test.js

Answer 2

我會建議你使用角度cli那裏你有引導項目很好的例子。

https://cli.angular.io/
