SyntaxError after following the setup instructions.

I followed the instructions in the README and ran into a SyntaxError right out of the gate. It seems like it's not interpretting as ES6:

hackday  $ create-react-app on-call-buddy

Creating a new React app in /Users/blakey/code/hackday/on-call-buddy.

Installing packages. This might take a couple minutes.

Success! Created on-call-buddy at /Users/blakey/code/hackday/on-call-buddy.

Inside that directory, you can run several commands:
  * npm start: Starts the development server.
  * npm run build: Bundles the app into static files for production.
  * npm run eject: Removes this tool. If you do this, you can’t go back!

We suggest that you begin by typing:
  cd /Users/blakey/code/hackday/on-call-buddy
  npm start

Happy hacking!

We require Node 4:

There is a bug in the CLI that it doesn’t check your Node version—that will be fixed in next release.

Thanks for reporting!

[dreadwail]

Ah. Thanks! My eyeballs scanned right over that one. Sorry for the noise.

[gaearon]

No problem, we should’ve fixed our Node detection code earlier!
