react中怎么安装sass

react中安装sass的方法：首先安装【sass-loader】和n【ode-sass】依赖；然后打开react的webpack配置，并进行相关修改即可。

react中安装sass的方法：

一、安装sass-loader和node-sass依赖

npm install sass-loader node-sass --save-dev

二、打开react的webpack配置

node_modules/react-scripts/config/webpack.config.js

找到module下的rules，oneof数组中，然后找到最后一个配置，修改成如下的样子

            {
              loader: require.resolve(&＃39;file-loader&＃39;),
              // Exclude `js` files to keep "css" loader working as it injects
              // its runtime that would otherwise be processed through "file" loader.
              // Also exclude `html` and `json` extensions so they get processed
              // by webpacks internal loaders.
              exclude: [/\.(js|mjs|jsx|ts|tsx)$/, /\.html$/, /\.json$/],
              options: {
                name: &＃39;static/media/[name].[hash:8].[ext]&＃39;,
              },
            },
            // ** STOP ** Are you adding a new loader?
            // Make sure to add the new loader(s) before the "file" loader.
          {
            test:/\.scss$/,
            loaders: [&＃39;style-loader&＃39;, &＃39;css-loader&＃39;, &＃39;sass-loader&＃39;]
          }
