npm install 因多层本地依赖项而失败

Question

如果我依赖的本地包本身又依赖于另一个本地包，那么 npm install 似乎不起作用。我正在使用 npm 版本 2.5.1.

这是我拥有的：

package.json 对于 /src/modules/moduleA:

{
  "name": "moduleA",
  "version": "0.0.1",
  ...
  "dependencies": {
    "bluebird": "^2.9.1",
    "nodemailer": "^1.3.0"
  }
}

package.json 对于 /src/modules/moduleB:

{
  "name": "moduleB",
  "version": "1.0.0",
  ...
  "dependencies": {
    "nconf": "~0.6.7",
    "moduleA": "../moduleA"
  }
}

package.json 对于 /src/apps/coolApp:

{
  "name": "coolApp",
  "version": "1.0.0",
  ...
  "dependencies": {
    "mysql": "~2.4.2",
    "request": "~2.40.0",
    "cheerio": "~0.17.0",
    "async": "~0.9.0",
    "expand-url": "0.1.3",
    "moduleB": "../../modules/moduleB"
  }
}

现在如果我尝试 npm install :

cd /src/modules/moduleA
npm install
    [success, yay!]

cd /src/modules/moduleB
npm install
    [success, yay!]

cd /src/apps/coolApp
npm install
    npm ERR! addLocal Could not install /src/node/apps/moduleA
    npm ERR! enoent ENOENT, open '/src/node/apps/moduleA'
    npm ERR! enoent This is most likely not a problem with npm itself
    npm ERR! enoent and is related to npm not being able to find a file.
[oh no!]

出于某种原因，npm 正在尝试为 coolApp 安装 moduleA，即使它不需要直接安装，而且它正在使用 package.json 中逐字指定的相对路径字符串moduleB 的文件，即使它对 coolApp 无效，因为它位于相对不同的位置。

我发现如果在路径前用 "file:" 指定本地模块，一切正常。耶

像这样：

"moduleB": "file:../../modules/moduleB"
