Add React Component to Laravel - laravel

Question

I'm new to Laravel and react and I just wanted to use react component along side with Laravel. I followed the process described here but when I run gulp watch I get this error:
C:\wamp64\www\laravel51\node_modules\laravel-elixir-webpack-react\main.js:3
Elixir.ready(function() {
^
TypeError: Elixir.ready is not a function

I also run command npm install --save-dev laravel-elixir-webpack-react but get same error.
my package.json file is:
{
"private": true,
"devDependencies": {
"gulp": "^3.8.8",
"laravel-elixir-webpack-official": "^1.0.10",
"laravel-elixir-webpack-react": "^1.0.1",
"react": "^15.4.2",
"react-dom": "^15.4.2"
},
"dependencies": {
"laravel-elixir": "^4.0.0",
"bootstrap-sass": "^3.0.0"
}
}
my gulpfile is:
var elixir = require('laravel-elixir');
require('laravel-elixir-webpack-react');
elixir(function(mix) {
mix.webpack('app.js');
});
and I work with Laravel 5.1 in windows.
