following instructions fails. Seems to be problem with .babelrc

[kylebakerio]

When I follow these instructions to the letter, everything works until the step where we move things over to a .babelrc file and remove the options from the scripts. Then I get a

[nodemon] starting `babel-node lib/index.js`
/usr/local/lib/node_modules/babel/node_modules/babel-core/lib/transformation/file/options/option-manager.js:126
      if (!option) this.log.error("Unknown option: " + alias + "." + key, ReferenceError);
                           ^

TypeError: Cannot read property 'error' of undefined
    at OptionManager.mergeOptions (/usr/local/lib/node_modules/babel/node_modules/babel-core/lib/transformation/file/options/option-manager.js:126:28)
