React中引入less、less-loader问题

//安装 less与less-loader
yarn add less less-loader --save-dev

//弹出默认配置，create-react-app创建的项目默认是没有webpack.config.js的
yarn eject

// 在webpack.config.js文件中，仿sass的引入
const lessRegex = /\.less$/;
const lessModuleRegex = /\.module\.less$/;

{
              test: lessRegex,
              exclude: lessModuleRegex,
              use: getStyleLoaders(
                {
                  importLoaders: 3,
                  sourceMap: isEnvProduction
                    ? shouldUseSourceMap
                    : isEnvDevelopment,
                },
                'less-loader'
              ),
              sideEffects: true,
            },
            {
              test: lessModuleRegex,
              use: getStyleLoaders(
                {
                  importLoaders: 3,
                  sourceMap: isEnvProduction
                    ? shouldUseSourceMap
                    : isEnvDevelopment,
                  modules: {
                    getLocalIdent: getCSSModuleLocalIdent,
                  },
                },
                'less-loader'
              ),
            }
