问题 如何用和声标志启动全局npm模块

我写了一个可以全局安装的npm模块 DM-NPM。

我喜欢在那个模块中使用co。

我怎么能告诉模块它在全局启动时以和声标志运行？

这是package.json：

{
  "name": "dm-npm",
  "version": "0.0.3",
  "description": "npm helper",
  "main": "index.js",
  "scripts": {
    "test": "mocha --reporter nyan",
    "start": "node --harmony ./bin/dm-npm"
  },
  "repository": {
    "type": "git",
    "url": "https://github.com/divramod/dm-npm.git"
  },
  "keywords": [
    "npm",
    "template"
  ],
  "author": "",
  "license": "ISC",
  "bugs": {
    "url": "https://github.com/divramod/dm-npm/issues"
  },
  "homepage": "https://github.com/divramod/dm-npm",
  "devDependencies": {
    "chai": "^2.1.0",
    "mocha": "^2.1.0"
  },
  "dependencies": {
    "co": "^4.4.0",
    "co-prompt": "^1.0.0",
    "colors": "~1.0.3",
    "shelljs": "^0.3.0"
  },
  "bin": {
    "dmnpm": "./bin/dm-npm"
  }
}

使用co函数运行时出现以下错误消息：

> $ dmnpm init                                                                                                                         
/usr/local/lib/node_modules/dm-npm/index.js:152
co(function*() {
           ^

    at Module._compile (module.js:460:26)
    at Object.Module._extensions..js (module.js:478:10)

它是由

co(function*() {
    var projectName =
        yield prompt('project name: '.blue);
    process.stdin.pause();
});
