Error when executing Handling of default exports demo

[sbenjamin]

I am attempting to run the demo code for: Handling of default exports.

I am using babel with numerous plugins "babel-cli": "^6.24.0", "babel-core": "^6.9.1", "babel-loader": "^6.2.4", "babel-plugin-istanbul": "^4.1.1", "babel-plugin-lodash": "^3.2.6", "babel-plugin-resolver": "^1.1.0", "babel-plugin-rewire": "^1.0.0", "babel-plugin-transform-es3-member-expression-literals": "6.8.0", "babel-plugin-transform-es3-property-literals": "6.8.0", "babel-plugin-transform-object-rest-spread": "^6.23.0", "babel-preset-es2015": "^6.9.0", "babel-preset-react": "^6.23.0", "babel-register": "^6.11.6", "babelify": "~6.3.0",

foo.js

function message() {
   return 'Hello world';
}

export function foo() {
   return message();
}

foo-spec.js import FooModule from './foo.js'; import { foo, RewireAPI as FooModuleRewireAPI } from './foo.js'; const chai = require('chai'); const expect = chai.expect();

describe('module default export test', function() {
   it('should demonstrate the default exported rewire api', function() {
      expect( foo() ).to.equal('Hello world');
      FooModule.__Rewire__('message', function() {
         return 'my message';
      });
      expect( foo() ).to.equal('my message');
      FooModule.__ResetDependency__('message');
   });

   it('should demonstrate the rewire apis named export', function() {
      expect( foo() ).to.equal('Hello world');
      FooModuleRewireAPI.__Rewire__('message', function() {
         return 'my message';
      });
      expect( foo() ).to.equal('my message');
      FooModuleRewireAPI.__ResetDependency__('message');
   });
});

The results are:

module default export test
    1) should demonstrate the default exported rewire api
    2) should demonstrate the rewire apis named export

  0 passing (35ms)
  2 failing

  1) module default export test should demonstrate the default exported rewire api:
     TypeError: _get__(...) is not a function
      at Context.<anonymous> (specs/data-layer/unit/foo-spec.js:8:7)

  2) module default export test should demonstrate the rewire apis named export:
     TypeError: _get__(...) is not a function
      at Context.<anonymous> (specs/data-layer/unit/foo-spec.js:17:7)

Please explain what it wrong.
