npm gulp 800a138f javascript错误

Question

当我把'gulp hello＆＃39;在cmd我得到此错误800a138f javascript对象预期错误

这是我的package.json文件

`{
 "name": "goes",
 "version": "1.0.0",
 "description": "",
 "main": "index.js",
 "scripts": {
    "start": "node gulp.js"
 },
"author": "",
"license": "ISC",
"devDependencies": {
    "gulp": "^3.9.1"
  }
 }`

这是gulp.js

 `var gulp = require('gulp');
 gulp.task('hello', function() {
 console.log('Hello Zell');
 });`
