Here is My Gruntfile

module.exports = function(grunt) { grunt.initConfig({ pkg: grunt.file.readJSON('package.json'), sass: { dist: { options: { debugInfo:false, style: 'expanded', precision: 3, lineNumbers: true }, files: { 'style.css' : 'style.scss' } } }, watch: { css: { files: 'assets/**/*.scss', tasks: ['sass'] } } }); grunt.loadNpmTasks('grunt-contrib-sass'); grunt.loadNpmTasks('grunt-contrib-watch'); grunt.registerTask('default',['watch']); }

I am getting error Could not find an option named "lineNumbers".
