Question

我知道已经有很多此问题的实例，但是没有一个实例可以解决我将Webpack与Sass一起使用时遇到的问题。

上下文：我正在使用npm安装material-design-lite，并在我的AddReminderView.ts文件中这样要求它：

require('material-design-lite/dist/material.css');
require('material-design-lite/dist/material.js');
require('../scss/styles.scss');

这是我的webpack配置，非常简单。

const path = require('path');

module.exports = {
    mode: 'development',
    entry: {
       add_trial: ['./src/views/AddReminderView.ts',
                  ]
    },
    module: {
      rules: [
        {
          test: /\.tsx?$/,
          loader: 'ts-loader',
          exclude: /node_modules/
        },
        {
          test: /\.scss$/,
          loader: ['style-loader', 'css-loader', 'sass-loader'],
          exclude: /node_modules/
        }
      ]
    },
    resolve: {
      extensions: [ '.tsx', '.ts', '.js' ]
    },
    output: {
      filename: '[name].js',
      path: path.resolve(__dirname, 'dist/js')
    }
  };

我收到的错误是这样的：

ERROR in ./node_modules/material-design-lite/dist/material.css 8:0
Module parse failed: Unexpected character '@' (8:0)
You may need an appropriate loader to handle this file type.

如何修复Webpack配置，以便可以正确包含.css文件？

编辑：

    "@types/node": "^10.5.2",

尝试将CSS webpack模块测试更新为此吗？

  module: {
    rules: [
      {
        test: /\.(sa|sc|c)ss$/,
        use: ["style-loader", "css-loader", "sass-loader"]
      }
    ]
  }
