javascript - meteor :ReferenceError:要求未定义

Question

我已经安装了 meteorhacks:npm 并在packages.json {"apn": "1.6.2"} 中定义了 apn。但是，当我运行以下代码时，出现错误 ReferenceError: require is not Defined:

var apn = Npm.require('apn'),
    path = Npm.require('path'),
    apnOptions = Meteor.settings.apnOptions || {},
    alertSound = apnOptions.sound || "alert.aiff",
    apnConnection

// default apn connection options
apnOptions = _.extend({
  cert: path.join(appRootPath, "private", "cert.pem"),
  key: path.join(appRootPath, "private", "key.pem"),
}, apnOptions)
apnConnection = new apn.Connection(apnOptions)

完整的错误消息:

对于通过 meteorhacks:npm 加载的包，使用 Meteor.npmRequire 代替 Npm.require 。例如:

var apn = Meteor.npmRequire('apn');
var path = Npm.require('path');

另请注意，需要 npm 包只能在服务器上运行，因此请确保代码位于您的 /server 目录中或由 Meteor.isServer 保护。
