napajs can not run in electron

[Leo sun]

I clone https://github.com/electron/electron-quick-start , add napa and electron-rebuild to rebuild napa,but when I run electron ,it throw error with

Error: The module '/Users/lixuexin/electron-quick-start/node_modules/napajs/bin/napa-binding.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 57. This version of Node.js requires
NODE_MODULE_VERSION 54. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or`npm install`).

electron-rebuild works well with my own addon.
here is the package.json

Hi, @Tomyail,
Which version of Node are you using? Is it a customized versions? You may check it by "node -v".
We can find

• NODE_MODULE_VERSION is 51 for all node v7..
• NODE_MODULE_VERSION is 57 for all node v8..
• NODE_MODULE_VERSION is 59 for all node v9..
  In the error message you provide, NODE_MODULE_VERSION 54.
  I would recommend to try it again with a standard node version. Because Napa.js provides pre-built bins only for them.
  For other versions of node, developers need to recompile it from their client.

Best regards, and Merry Christmas!
Allen.

@helloshuangzi the node is bundle in electron , so i can't change this version. I use this link and get the follow info:

{
    "http_parser": "2.7.0", 
    "node": "7.9.0", 
    "v8": "5.8.283.38", 
    "uv": "1.11.0", 
    "zlib": "1.2.11", 
    "ares": "1.10.1-DEV", 
    "modules": "54", 
    "openssl": "1.0.2k", 
    "electron": "1.7.10", 
    "chrome": "58.0.3029.110", 
    "atom-shell": "1.7.10"
}

and I will try compile napa from source

@Tomyail I've added a new wiki page at https://github.com/Microsoft/napajs/wiki/Build-Napa.js-for-Electron. Please let me know if you have any questions.
