Node.js NPM：找不到npm link模块后

我正在为NodeJS开发两个模块，第一个名为aligator，第二个名为aligator-methods.第二个取决于第一个.我正在同时开发这两个模块，我想全局链接aligator，这样我就可以像在npm注册表上一样使用它，我只是在全局范围内安装了它.为了完成这个NPM文档，我需要使用npm link，但它不起作用.

模块aligator的文件package.json:

{
  "name": "aligator",
  "version": "0.0.1",
  "description": "",
  "main": "index.js",
  "private": true,
  "directories": {
    "doc": "docs",
    "example": "examples",
    "test": "spec"
  },
  "scripts": {
    "test": "gulp jasmine"
  },
  "license": "MIT",
  "devDependencies": {
    "gulp": "^3.6.2",
    "gulp-jasmine": "^0.2.0",
    "gulp-jshint": "^1.6.1",
    "gulp-rename": "^1.2.0",
    "jasmine-node": "^1.14.3"
  },
  "dependencies": {
    "bluebird": "^1.2.4",
    "lodash": "^2.4.1",
    "mathjs": "^0.22.0"
  }
}

模块aligator-methods的文件package.json:

{
 "name": "aligator-methods",
 "version": "0.0.1",
 "description": "",
 "main": "index.js",
 "private": true,
 "directories": {
   "doc": "docs",
   "example": "examples",
   "test": "jasmine"
 },
 "scripts": {
   "test": "gulp jasmine"
 },
 "author": "",
 "license": "MIT",
 "devDependencies": {
   "gulp": "^3.6.2",
   "gulp-jasmine": "^0.2.0",
   "gulp-jshint": "^1.6.1",
   "gulp-rename": "^1.2.0",
   "jasmine-node": "^1.14.3"
 },
 "dependencies": {
   "lodash": "^2.4.1",
   "mathjs": "^0.22.0",
   "aligator": "^0.0.1"
 }
}

首先，我将模块链接到全球:

$ cd ~/aligator
$ npm link
/usr/local/lib/node_modules/aligator -> /Users/roc/aligator

如果我没弄错的话，这已经为我的模块aligator创建了一个全局引用，现在我可以在计算机中的任何地方使用这个模块.

然后我转到另一个模块，try 安装依赖项，但它给了我以下输出:

$ cd ~/aligator-methods
$ npm install
npm ERR! 404 404 Not Found: aligator
npm ERR! 404
npm ERR! 404 'aligator' is not in the npm registry.
npm ERR! 404 You should bug the author to publish it
npm ERR! 404 It was specified as a dependency of 'aligator-methods'

npm ERR! code E404
npm ERR!
npm ERR! Additional logging details can be found in:
npm ERR!     /Users/roc/aligator-methods/npm-debug.log

我甚至试图将其与以下内容直接联系起来:

$ cd ~/aligator-methods
$ npm link aligator
/Users/roc/aligator-methods/node_modules/aligator -> /usr/local/lib/node_modules/aligator -> /Users/roc/aligator

但它也不起作用.

Any thoughts on what it is that could be happening?我在某个地方读到，它可能与我安装的node和npm有关，因为它是brew 的，所以有时我需要使用sudo，这似乎不太可能，但我try 了他们提出的方法，但也没有成功.
