reactjs - 将 Grommet 与 ReactJS webpack 和 scss 导入问题一起使用

Question

我正在尝试在我的 React 项目中使用索环，并且我正在使用 webpack。我添加了 scss 加载程序，当我构建我的应用程序时，我收到以下错误：

ERROR in ./~/css-loader!./~/sass-loader!./scss/index.scss
Module build failed: 
@import "inuit-defaults/settings.defaults";
^
      File to import not found or unreadable: inuit-defaults/settings.defaults
Parent style sheet: /Users/hduser/sample-app/node_modules/grommet/scss/grommet-core/_settings.scss
      in /Users/hduser/sample-app/node_modules/grommet/scss/grommet-core/_settings.scss (line 2, column 1)
 @ ./scss/index.scss 4:14-116 13:2-17:4 14:20-122

不知道我做错了什么..

这是我的 webpack.config.js

var webpack = require('webpack');
var path = require('path');

module.exports ={
    devtool :'cheap-module-eval-source-map',
    entry:[
        'webpack/hot/only-dev-server',
        './index.jsx'
    ],
    module:{
        loaders:[
            {
                test: /\.jsx?$/,
                exclude :/node_modules/,
                include: __dirname,
                loader:'react-hot'
            },
            {
                test: /\.jsx?$/,
                exclude :/node_modules/,
                include: __dirname,
                loader:'babel',
                query:{
                    "plugins":["transform-decorators-legacy"],
                    "presets":["es2015","react"]
                }
            },
            {
                test :/\.css?$/,
                include: __dirname,
                loaders :['style','css']
            },
            {
                test: /\.less$/,
                loader: "style!css!less"
            },
            {
                test: /\.json$/,
                loader: "json"
            },
            {
                test: /\.scss$/,
                loaders: ["style", "css", "sass"]
            }
        ]
    },
    resolve:{
        extensions:['','.js','.jsx']
    },
    output:{
        path: __dirname+'/',
        publicPath:'/',
        filename:'bundle.js'
    },
    devServer:{
        contentBase: './',
        hot:true
    },
    plugins: [
        new webpack.HotModuleReplacementPlugin()
        ,new webpack.NoErrorsPlugin()
    ]
}

Answer 1

如果您使用 npm3+ 进行更新，您可以简单地执行此操作（请参阅此处 alan 的解释）：

{
    test: /\.scss$/,
    loader: 'style!css!sass?outputStyle=expanded&' +
      'includePaths[]=' +
      (encodeURIComponent(path.resolve('./node_modules')))
},

---

或像这样编写 scss 加载器：

{
  test: /\.scss$/,
  loader: "style!css!sass?OutputStyle=expaned&" +
  'includePaths[]=' +
  (encodeURIComponent(
    path.resolve(process.cwd(), './node_modules')
  )) +
  '&includePaths[]=' +
  (encodeURIComponent(
    path.resolve(process.cwd(),
    './node_modules/grommet/node_modules'))
  )
}

Answer 2

我通过遵循 Webpack 2 约定来修复它。

{
  test: /(\.scss$)/,
  loaders: [{
    loader: 'style-loader'
  }, {
    loader: 'css-loader'
  }, {
    loader: 'sass-loader',
    options: {
      outputStyle: 'compressed',
      includePaths: ['./node_modules']
    }
  }]
}

在我这边工作得很好！

Answer 3

我有同样的问题，并通过这种方式得到这个工作：

var ExtractTextPlugin = require('extract-text-webpack-plugin');

module.exports = {
    // ...
    module: {
        loaders: [
            // ...
            {
                test: /\.scss$/,
                loader: ExtractTextPlugin.extract('css!sass')
            }
        ]
    },
    sassLoader: {
      includePaths: [ './node_modules' ]
    },
    plugins: [
        new ExtractTextPlugin('public/grommet.css', {
            allChunks: true
        })
    ]
}

但是记得将生成的css文件导入到你的index.html中

Answer 4

在 webpack 配置中使用以下 scss 加载器（感谢https://github.com/primozs)

{
                test: /\.scss$/,

                loader: 'style!css!sass?outputStyle=expanded&' +
                'includePaths[]=' +
                (encodeURIComponent(
                    path.resolve(process.cwd(), './node_modules')
                )) +
                '&includePaths[]=' +
                (encodeURIComponent(
                        path.resolve( process.cwd(),
                            './node_modules/grommet/node_modules'))
                )
            }
