Getting an error when I run NPM live-server

Question

Here's the server I'm using, https://www.npmjs.com/package/live-server. However, when I try to use ~/.live-server.json as the configuration file, I always fail... Here's what I have in the file, and it's very simple.

{
   port: "8001"
}

Then I have this error when I run live-server

undefined:2
   port: "8001"
   ^    

SyntaxError: Unexpected token p
    at Object.parse (native)
    at Object.<anonymous> (/usr/local/lib/node_modules/live-server/live-server.js:17:20)
    at Module._compile (module.js:435:26)

    at Function.Module.runMain (module.js:467:10)
    at startup (node.js:136:18)
    at node.js:963:3

I don't know why this is happening.

Property names in JSON must be quoted (JSON is not JavaScript):

{
   "port": "8001"
}

Thanks! I tried "port": 8001, but not both of them. – Bomin Dec 09 '15 at 15:55
`{ "port": 8001 }` is valid JSON. The difference is that `8001` is a number value and `"8001"` is a string value, like in JavaScript. – Jordan Running Dec 09 '15 at 15:56

It should be:

{
    "port": 8001
}

Add explanation: well, in JSON, name should always double quoted, and value should also be double quoted, except number (if you double quote a number, it becomes a string). Like this:

{
    "name1": "stringValue",
    "name2": aNumber
}
