Reactjs css加载程序，sass加载程序不工作网页包2

我正在从网页1迁移到网页2。我遵循了webpack迁移指南，但是，在解析css文件时，我发现了以下错误。我尝试了一个网站，不在ExtractTextPlugin.extract上使用“use”，但它也不起作用。 网页包版本-“网页包”：“2.2.1”，

 Module parse failed: /home/gameon/Desktop/venue_lisiting/node_modules/extract-text-webpack-plugin/loader.js?{"omit":1,"remove":true}!style-loader!css-loader!postcss-loader!sass-loader!/home/gameon/Desktop/venue_lisiting/src/styles/desktop.scss Unexpected character '@' (1:0)
 You may need an appropriate loader to handle this file type.

我想这可能是加载器的顺序，所以POSTSS加载器应该是最后一个。无论如何，这里有一个Webpack2的工作配置示例，您可以按照这个示例进行操作

希望有帮助：）

保持

new ExtractTextPlugin("[name].css"),

在

插件

和

模块

中修改css规则如下：

...
{
    test: /\.scss$/,
    use: ExtractTextPlugin.extract({
        fallback: "style-loader",
        use: [
            {
                loader: 'css-loader',
                options: {
                    modules: true 
                }
            },
            'postcss-loader',
            'sass-loader'
        ]
    }),
},
...

装载机的订单不是问题。我刚查过。
