SyntaxError: Unexpected reserved word

[luandro]

Just installed a fresh copy of gatsby, and created a blog. When I try to run gatsby serve I get this error:

/usr/local/lib/node_modules/gatsby/lib/utils/serve.js:2
import Hapi from 'hapi';
^^^^^^
SyntaxError: Unexpected reserved word

Seems like babel isn't running for some reason. Any clues?

I think I removed it accidentally earlier... though it was working on my
machine. I'll be home in a bit and will fix and release. Thanks for filing
an issue!

In the meantime downgrade to 0.5.0 which is almost identical.

👍

Hmmm... so babel-node doesn't work with globally installed packages...
babel/babel#1889

It's suggested that you pre-compile your code... not fun...

[KyleAMathews]

Ok, I think things should work now with 0.6.1.

@gesposito looks like we're either going to have to go vanilla ES5 or pre-compile code.

[gesposito]

What are the steps to reproduce this?
I have 0.6.0 -g installed and I tested serve against all the starter sites and they worked.

[KyleAMathews]

Basically that :) Did you run npm link though against your local clone of Gatsby? It does work in that scenario which is why I didn't detect it until @luandro reported the bug.

[gesposito]

Yeah, I still had the npm linked version on.
I'll take a look at it if I can.

So, I dug a bit, and found that babel actually might ignore gatsby because its ignore includes node_modules where gatsby is npm installed (as per babel/babel#1270, babel/babel#1889 as you referenced).

Some solutions that I couldn't get to work are:

reverse ignore gatsby:

require('babel/register')({
  ignore: /node_modules\/(?!gatsby)/
});

or explicitly include

require("babel/register")({
  only: ["gatsby/lib"]
});

use env babel-node*

#!/usr/bin/env babel-node

spawn a child process/command*

./node_modules/.bin/babel-node --harmony ./bin/cli.js

*Note: both babel-node based solutions are not meant for production use.

Last one, that is the advised solution is to

precompile, i.e.:

"compile": "coffee --output dist --compile lib && babel -d dist/ lib/",
"prepublish": "npm run compile"

that would require some project restructuring.

[KyleAMathews]

Thanks for your research! Yeah, precompile is doable but takes some careful setup.
