我正在尝试根据本指南从 webpack 1 迁移到 2 。我进行了大部分更改，但在使用 ExtractTextPlugin 时遇到了困难。这是当前使用 webpack 1 的样子：

 module: {
    loaders: [
      {
        test: /\.jsx?$/,
        exclude: /(node_modules|vendor)/,
        loader: 'babel',
        query: {
          presets: ['es2015', 'stage-0', 'react']
        }
      },
      {
        test: /\.css$/,
        loader: ExtractTextPlugin.extract('style-loader', 'css-loader', 'autoprefixer-loader')
      },
      {
        test: /\.styl$/,
        loader: ExtractTextPlugin.extract('style-loader', 'css-loader!autoprefixer-loader!stylus-loader')
      },
      {
        test: /\.(woff|woff2|ttf|eot)($|\?)/,
        loader: 'file-loader?name=[path][name].[ext]'
      },
      {
        test: /\.svg\?/,
        loader: 'url-loader?limit=100000&name=[path][name].[ext]'
      },
      {
        test: /\.(png|gif|jpg|svg)$/,
        loader: 'file-loader?name=[path][name].[ext]'
      },
    ]
  }

我对 webpack2 所做的更改：

module: {
    rules: [
      {
        test: /\.jsx?$/,
        exclude: /(node_modules|vendor)/,
        use:[{
            loader: 'babel-loader',
            query: { //
              presets: ['es2015', 'stage-0', 'react']
            }
          }
        ]
      },


      {
    test: /\.css$/,
    use: ExtractTextPlugin.extract({
      fallback:'style-loader',
      use: ['css-loader', 'postcss-loader','stylus-loader']
    })
  },
  {
    test: /\.styl$/,
    use: ExtractTextPlugin.extract({
      fallback:'style-loader',
        use: ['css-loader', 'postcss-loader','stylus-loader']
    })
  },


      {
        test: /\.(woff|woff2|ttf|eot)($|\?)/,
        use: 'file-loader?name=[path][name].[ext]'
      },
      {
        test: /\.svg\?/,
        use: 'url-loader?limit=100000&name=[path][name].[ext]'
      },
      {
        test: /\.(png|gif|jpg|svg)$/,
        use: 'file-loader?name=[path][name].[ext]'
      },
    ]
  }

但这会导致错误。我在哪里可以找到有关迁移这部分 webpack 配置的帮助。

我看到的一些错误：

ERROR in ./~/css-loader!./~/postcss-loader!./~/stylus-loader!./~/bootstrap/dist/css/bootstrap.css
Module build failed: ParseError: C:\temp\node_modules\bootstrap\dist\css\bootstrap.css:3586:71

   3587| }
   3588| .open > .dropdown-menu {

你也在stylus-loader为你使用.css。但并非所有 CSS 都是有效的手写笔。您需要stylus-loader从.css规则中删除：

{
  test: /\.css$/,
  use: ExtractTextPlugin.extract({
    fallback: 'style-loader',
    use: ['css-loader', 'postcss-loader']
  })
},
