1、下载
    	cnpm install --save less less-loader
    	
    2、在node-modules/react-scripts/config/webpack.config.js中
      或者npm run eject,在弹出的config中的webpack.config.js中修改
    	
    	(1)大概61行后,sass匹配后面放置less
    	
    		const lessRegex = /\.less$/;
    		const lessModuleRegex = /\.module\.less$/;
    		
    	(2)ctrl+f搜索sassRegex,复制一份sassRegex配置,将sass内容修改成less
    		
            {
              test: sassRegex,
              exclude: sassModuleRegex,
              use: getStyleLoaders(
                {
                  importLoaders: 3,
                  sourceMap: isEnvProduction && shouldUseSourceMap,
                },
                'sass-loader'
              ),
              // Don't consider CSS imports dead code even if the
              // containing package claims to have no side effects.
              // Remove this when webpack adds a warning or an error for this.
              // See https://github.com/webpack/webpack/issues/6571
              sideEffects: true,
            },
            {
              test: lessRegex,
              exclude: lessModuleRegex,
              use: getStyleLoaders(
                {
                  importLoaders: 3,
                  sourceMap: isEnvProduction && shouldUseSourceMap,
                },
                'less-loader'
              ),
              // Don't consider CSS imports dead code even if the
              // containing package claims to have no side effects.
              // Remove this when webpack adds a warning or an error for this.
              // See https://github.com/webpack/webpack/issues/6571
              sideEffects: true,
            },
            
    	(3)ctrl+f搜索sassModuleRegex,复制一份sassModuleRegex配置,将sass内容修改成less
    	
    	    {
              test: sassModuleRegex,
              use: getStyleLoaders(
                {
                  importLoaders: 3,
                  sourceMap: isEnvProduction && shouldUseSourceMap,
                  modules: {
                    getLocalIdent: getCSSModuleLocalIdent,
                  },
                },
                'sass-loader'
              ),
            },
            {
              test: lessModuleRegex,
              use: getStyleLoaders(
                {
                  importLoaders: 3,
                  sourceMap: isEnvProduction && shouldUseSourceMap,
                  modules: {
                    getLocalIdent: getCSSModuleLocalIdent,
                  },
                },
                'less-loader'
              ),
            },
    		
    3、重启项目
