I select all the plug-in and bootstrap, and created the project. Then, this error: TypeError: Cannot read property 'optOut' of null
However, the creation of a project itself is end to no error.

Out of the box I include HTML5 Boilerplate, jQuery, and a Gruntfile.js to build your app.
? What more would you like? Bootstrap
   create cordova/.gitignore
   create fake/cordova.js
   create cordova/www/.gitkeep
   create Gruntfile.js
   create package.json
   create .gitignore
   create .gitattributes
   create .bowerrc
   create bower.json
   create .jshintrc
   create .editorconfig
   create app/styles/main.css
   create app/favicon.ico
   create app/robots.txt
   create app/index.html
   create app/scripts/main.js
   invoke   mocha

I'm all done. Running bower install & npm install for you to install the required dependencies. If this fails, try running the command yourself.

   create     test/bower.json
   create     test/.bowerrc
   create     test/spec/test.js
   create     test/index.html
