NPM:在“npm 链接"之后找不到模块 [英] NPM: After "npm link" module is not found

问题描述

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工作.我正在同时开发这两个模块，我想全局链接 aligator 以便我可以像在 npm 注册表中一样使用它，并且我只是全局安装了它.要执行此 NPM 文档，我需要使用 npm link 但它不起作用.

I'm developing two modules for NodeJS, first one named aligator and second one aligator-methods. Second one depends on first one to work. I'm developing these two modules at the same time and I want to global link aligator so I can use it like it is on npm registry and I just installed it globally. To do this NPM documentation says that I need to use npm link but it's not working.

aligator模块的package.json文件:

{
  "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"
  }
}

aligator-methods模块的package.json文件:

{
 "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"
 }
}

首先我全局链接模块:

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

如果我没有记错的话，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.

This if I'm not mistaken has created a global reference of my module aligator and now I can use this module from everywhere I want in the computer.

然后我转到另一个模块并尝试安装依赖项，但它给了我这个输出:

Then I went to the other module and tried to install the dependency but it gave me this output:

$ 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

我什至试图将它直接链接到:

I even tried to link it directly with:

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

但也没有用.

对可能发生的事情有任何想法吗?我在某处读到这可能与我安装 node 和 npm 因为它是由 Homebrew 制作的，所以有时我需要使用 sudo，这似乎不太可能，但我尝试了他们提出的建议，但也没有用.

Any thoughts on what it is that could be happening? I read somewhere that maybe it had something to do with my installation of node and npm because it was made by Homebrew and so sometimes I need to use sudo, it seemed unlikely but I tried what they proposed and It didn't work either.

推荐答案

问题是 package.json 的 main 属性指向一个不存在的文件.似乎问题可能由于多种原因而发生，因此请务必查看其他答案.

The problem was that the main property of package.json was pointing to a non-existing file. It seems that the problem can happen due to multiple reasons so be sure to take a look at other answers.
