webpack编译less出错?报错

 问题描述：使用webpack编译并提取less文件时报错

ERROR in ./src/css/studio.less
Module build failed: TypeError: require(...) is not a function
    at D:\Projects\Sprite\workflow-studio\src\css\studio.less:16:74
    at ContextifyScript.Script.runInContext (vm.js:35:29)
    at ContextifyScript.Script.runInNewContext (vm.js:41:15)
    at Object.extractLoader (D:\Projects\Sprite\workflow-studio\node_modules\extract-loader\lib\extractLoader.js:88:12)

webpack配置如下：

       {
                test:/\.less$/,
                use: [
                    'file-loader',
                    'extract-loader','style-loader', 'css-loader','less-loader']
            },
