需要节点模块中另一个依赖项的依赖项 [英] Require dependency of another dependency in node modules

问题描述

我有一个简单的节点应用程序，它只依赖于 github 上的另一个应用程序.使用 npm install 可以很好地安装依赖项，但是当我尝试要求在那里安装某些东西时，它说它不可用.例如，github 应用程序安装 Mongoose 作为依赖项.我认为这个父应用程序将能够访问该模块，因为它在一个孩子中:

I've got a simple node app that has single dependency on another app on github. The dependency installs just fine with npm install, but when I try to require something installed there, it says it's not available. For example, the github app installs Mongoose as a dependency. I thought that this parent app would be able to access that module since it is in a child:

var mongoose = require('mongoose')

结构如下:

/app
  /node_modules
    /github_dependency [parent module]
      /node_modules
        /mongoose [child module]

我是否只需要将 mongoose 作为依赖项也包含在父应用程序中，或者是否有办法通过子应用程序访问该模块?

Do I just have to include mongoose as a dependency as well in the parent app or is there a way of getting access to that module by way of the child?

虽然您可能例如require('github/node_modules/mongoose')，标准做法是显式安装所有依赖项(即，您应该将 mongoose 作为应用程序的依赖项)和 require('猫鼬').

While it's possible for you to e.g. require('github/node_modules/mongoose'), the standard practice is to install all of your dependencies explicitly (i.e., you should include mongoose as a dependency of your app) and require('mongoose').
