Can't npm start new app, SyntaxError: Unexpected token => on a fresh install

[olivier-w]

Edit from maintainers: the project requires Node >= 4.0.
We’ll fix the CLI to report an error in earlier versions.

I can't get the local server started. My steps to the error:

• npm install -g create-react-app
• create-react-app hello
• No errors creating the app
• cd hello
• npm start

@olivier-w what node version are you using?

[olivier-w]

@conorhastings v0.12.7. Is there a recommended npm/node version that I should be using?

[conorhastings]

@olivier-w This requires node >= 4 in order to run since it was uses arrow functions etc...

[olivier-w]

@conorhastings Working with node v4.4.7 installed. Thank you!

Hmm wasn't CLI supposed to check for the Node version before installing?
Let's reopen for now to investigate.

@gaearon looks like it isn't called anywhere https://github.com/facebookincubator/create-react-app/blob/master/global-cli/index.js#L139-Lundefined

edit: @keyanzhang mentioned that in #68 (comment)

[conorhastings]

[gaearon]

Ah, good points. Want to fix this? 😄

I think I just hit this bug. I know this was integrated but has the template been updated? Hate to ask, but I'm just getting my started with this (Coming from Ruby/HTML/SCSS)

Currently on Node 6.7.0 and npm 3.10.7.

If you have Node 6 you can't have this issue. Please file a new issue describing your problem in detail. Thanks!
