webpack，angular 2，css和sass的设置问题

[从原始发行版更新]我正在尝试安装带有webpack的Angular2的最新版本来处理sass。我现在正在处理scss文件。但是，现在的问题在于CSS。webpack，angular 2，css和sass的设置问题

我已经添加了以下到app.component.ts文件...

require('../../node_modules/bootstrap/dist/css/bootstrap.css'); 
require('../../public/styles/styles.scss');

我正在从故宫开始生成错误...

./~/bootstrap/dist/css/bootstrap.css 
Module build failed: ReferenceError: window is not defined 
bootstrap\dist\css\bootstrap.css doesn't export content

的相关位webpack.common.js ...

{ 
    test: /\.css$/, 
    loader: ExtractTextPlugin.extract({ loader: [{ loader: "style-loader" }, { loader: "css-loader" } ] }) 
    }, 
    { 
    test: /\.scss$/, 
    loader: ExtractTextPlugin.extract({ loader: [{ loader: "css-loader" }, { loader: "sass-loader" } ] }) 
    }

从我的package.json的一个片段：

"devDependencies": { 
"@types/jasmine": "2.5.38", 
"@types/node": "^6.0.42", 
"codelyzer": "~2.0.0-beta.1",

"postcss-loader": "1.2.2", 
"webpack": "2.2.1",

}

我一直在试图解决这个好几天。任何帮助深表感谢。

我删除了我的答案，尝试根据插件示例更改您的配置。 https://github.com/jtangelder/sass-loader –

查看插件示例，我将我的webpack配置更改为：{ test：/\.scss$/， loader：ExtractTextPlugin.extract（{loader：[{ 装载机： “CSS-装载机” }，{ 装载机： “青菜装载机” }]， fallbackLoader： “风格装载机” }） }现在我得到这个错误“预期 '风格' 是一个字符串数组“我有一个组件，这个styleUrls：['./invoice-list.component.scss']，如果我注释掉错误消失 –

嗨，李，安装'raw-loader'，并使用它之前'CSS-loader'。这应该将'预期'风格'的问题理清为字符串数组' – Ruaghain

所以，我找到了答案。看起来角度文档已经过时了，还有webpack文档。

我结束了这是我的工作配置文件...

var webpack = require('webpack'); 
var HtmlWebpackPlugin = require('html-webpack-plugin'); 
var ExtractTextPlugin = require('extract-text-webpack-plugin'); 
var helpers = require('./helpers'); 

module.exports = { 
    entry: { 
    'polyfills': './src/polyfills.ts', 
    'vendor': './src/vendor.ts', 
    'app': './src/main.ts' 
    }, 

    resolve: { 
    extensions: ['.ts', '.js', '.json', '.css', '.scss', '.html'] 
    }, 

    module: { 
    rules: [ 
     { 
     test: /\.ts$/, 
     loaders: [{ 
      loader: 'awesome-typescript-loader', 
      options: { configFileName: helpers.root('src', 'tsconfig.json') } 
     }, 
     'angular2-template-loader'] 
     }, 
     { 
     test: /\.html$/, 
     loader: 'html-loader' 
     }, 
     { 
     test: /\.(png|jpg|jpe?g|gif|svg|woff|woff2|ttf|eot|ico)$/, 
     loader: 'file-loader?name=assets/[name].[hash].[ext]' 
     }, 
     { 
     test: /\.css$/, 
     loader: ExtractTextPlugin.extract({ loader: [{ loader: "css-loader" }, { loader: "postcss-loader" } ]}) 
     }, 
     { 
     test: /\.scss$/, 
     loader: ExtractTextPlugin.extract({ loader: [{ loader: "css-loader" }, { loader: "sass-loader" } ] }) 
     } 
    ] 
    }, 

    plugins: [ 
    new ExtractTextPlugin({ filename: 'css/[name].css', disable: false, allChunks: true }), 
    // Workaround for angular/angular#11580 
    new webpack.ContextReplacementPlugin(
     // The (\\|\/) piece accounts for path separators in *nix and Windows 
     /angular(\\|\/)core(\\|\/)(esm(\\|\/)src|src)(\\|\/)linker/, 
     helpers.root('./src'), // location of your src 
     {} // a map of your routes 
    ), 

    new webpack.optimize.CommonsChunkPlugin({ 
     name: ['app', 'vendor', 'polyfills'] 
    }), 

    new HtmlWebpackPlugin({ 
     template: 'src/index.html' 
    }) 
    ] 
};

然后我说需要声明为全局CSS要求app.component.ts文件，然后使用的样式属性上用于组件特定样式的嵌套组件。

下面是一个适用于我的关于scss使用的示例。请注意，我不会将生成的CSS编译到单独的文件中，这一点很重要。它在我生成的js文件中作为模块生成：

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