Material-UI not working (using nwb)

Question

After click:

I try to test Material-UI components. My steps:

1. I installed nwb globally: sudo npm install -g nwb

2. I created a new React application: nwb new react-app myapp

3. I look inside: cd myapp

4. I edited nwb.config.js (since Webpack creates absolute path with "/"):

   module.exports = {
     webpack: {
       publicPath: ''
     }
   }
   

5. I installed requested plugin: npm i --save react-tap-event-plugin

6. I added font Roboto in index.html:

<link href="https://fonts.googleapis.com/css?family=Roboto:300,400,500" rel="stylesheet">

7. I added links to icons (because Material-UI didn't show icons by default):

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

8. I installed and started a server: npm start --auto-install

After starting I see an error

Invariant Violation: addComponentAsRefTo(...)

Only first button reacts on a click but it's not animation! And other buttons don't react on any clicks.

9. In the package.json I inserted ammendments in version of a plugin:

   "dependencies": { "react": "^15.4.1", "react-dom": "^15.4.1", "react-tap-event-plugin": "^2.0.1" },

based on information from: ERROR in ./~/react-tap-event-plugin/src/injectTapEventPlugin.js

Due to update in React, react-tap-event-plugin breaks Change react-tap-event-plugin to ^2.0.0 in your package.json if using react version ^15.4.0.

Sorry, I don't have anymore any ideas how to fix it! It's not working in Safari and in Chrome as well. Thank you for any help! All examples from official site Material-UI/Components
