'require is not defined' in Meteor.js when including NPM package
提问by Nyxynyx
I'm trying to use a npm package from Meteor.js (Release 0.6.6.3)using Meteor.require. However it throws an error saying that requireis not defined. Why is this and how can we solve it?
我试图使用从Meteor.js一个NPM包（版本0.6.6.3）使用Meteor.require。但是它抛出一个错误，说require没有定义。为什么会这样，我们该如何解决？
mrt add npm
npm install github
packages.json
包.json
{
"github": "0.1.8"
}
github.js
github.js
var GITHUB = Meteor.require('github');
Error
错误
ReferenceError: require is not defined
The npm package has lines such as
npm 包中有几行，例如
var https = require('https')
var url = require('url')
var crypto = require('crypto')
Must the package's code be manually edited to use Npm.require? Editing them manually got rid of the errors.
必须手动编辑包的代码才能使用Npm.require吗？手动编辑它们消除了错误。
However theres a line:
但是有一行：
module.exports = SOMETHING
How should we call modulefrom within meteor?
我们应该如何module从流星内部呼叫？

Meteor.requireis a function added by the meteor npm smart package, which actually doesn't do much for using npm other than wrapping some asynchronous callbacks. It's a few months old, so you might want to try using Meteor's Npm.requiredirectly in case something broke.
Meteor.require是流星 npm 智能包添加的一个函数，除了包装一些异步回调之外，它实际上对使用 npm 没有太大作用。它已经有几个月的历史了，因此您可能想尝试Npm.require直接使用 Meteor ，以防万一出现问题。
The monkey-patching of the Meteorglobal by this package is misleading.
Meteor这个包对全局的猴子补丁具有误导性。

Making comments above an answer.
在答案上方发表评论。
Is Meteor.require() a typo? That is what is in your code though your question text refers to the correct Npm.require().
Meteor.require() 是错字吗？尽管您的问题文本指的是正确的 Npm.require()，但这就是您的代码中的内容。
I think module.exports is there for non-meteor use of the same file. Within meteor variables for export should be
我认为 module.exports 可用于非流星使用同一文件。在用于导出的流星变量中应该是
- declared as globals inside the package
- exported with api.export() within the package.js file.
- 在包内声明为全局变量
- 在 package.js 文件中使用 api.export() 导出。
The documentation on this is a bit rough but look at namespacingand writing packages. Also looking into the various meteor packageson github is very useful.

Make sure you're using the meteor-npmpackage.
确保您正在使用该meteor-npm软件包。

Use Npm.require() in meteor.
在流星中使用 Npm.require()。
Like this:
像这样：
var fs = Npm.require("fs");
For that you need to have a Meteor package: meteorhacks:npm, npm-container
对于您需要有一个流星包：meteorhacks:npm，npm-container
