3 Repro steps. Was this an app that wasn't created using the CLI? What change did you
do on your code? etc.

I generated a new project with angular-cli 1.0.0-beta.11-webpack.2 using the command

ng new pftest --prefix pft.

Then I successfully ran ng serve and ng test, but encountered a failure when I ran ng e2e.

4 The log given by the failure. Normally this include a stack trace and some
more information.

Results of command ng e2e:

Could not start watchman; falling back to NodeWatcher for file system events.

5 Mention any other details that might be useful.

From e2e/app.e2e-spec.ts:

it('should display message saying app works', () => {
page.navigateTo();
expect(page.getParagraphText()).toEqual('pft works!');
});

After encountering this error with a new project and the prefix 'fam', I reproduced it by starting a brand new project (named pftest) with the ng new command and the --prefix option, using the prefix pft.
