Javascript 为什么everyauth与'；未定义不是函数'；？

我的代码如下

var express = require('express'),
    everyauth = require('everyauth'),
  util = require('util'),
  Promise = everyauth.Promise,
  users = require('./users');

everyauth.twitter
  .consumerKey('')
  .consumerSecret('')
  .findOrCreateUser(function(session, accessToken, accessTokenSecret, twitterUserData) {
    console.log('pre promise');
    var promise = new Promise();
   users.findOrCreateByTwitterData(twitterUserData, promise);
    return promise;
  })
  .redirectPath('/');

pre promise

/.../node_modules/everyauth/lib/modules/everymodule.js:348
  throw err;
        ^
TypeError: undefined is not a function
    at Object._findOrCreateUser ( .../test.js:12:19)
    at Object.exec ( .../node_modules/everyauth/lib/step.js:47:21)
    at  .../node_modules/everyauth/lib/stepSequence.js:26:38
    at [object Object].fulfill ( .../node_modules/everyauth/lib/promise.js:42:25)

    at passBackControl ( .../node_modules/everyauth/node_modules/oauth/lib/oauth.js:359:11)
    at IncomingMessage.<anonymous> ( .../node_modules/everyauth/node_modules/oauth/lib/oauth.js:378:9)
    at IncomingMessage.emit (events.js:88:20)

它打印“预承诺”，然后崩溃如下

var express = require('express'),
    everyauth = require('everyauth'),
  util = require('util'),
  Promise = everyauth.Promise,
  users = require('./users');

everyauth.twitter
  .consumerKey('')
  .consumerSecret('')
  .findOrCreateUser(function(session, accessToken, accessTokenSecret, twitterUserData) {
    console.log('pre promise');
    var promise = new Promise();
   users.findOrCreateByTwitterData(twitterUserData, promise);
    return promise;
  })
  .redirectPath('/');

pre promise

/.../node_modules/everyauth/lib/modules/everymodule.js:348
  throw err;
        ^

我对everyauth 0.2.32也有同样的问题。 看起来everyauth.Promise未被导出，当您尝试实例化“未定义”类时，应用程序崩溃

您可以检查（Promise==“undefined”）

在everyauth的最新版本中，是否应使用以下语法：

.findOrCreateUser(function(session, accessToken, accessTokenSecret, twitterUserData) {
    var promise = this.Promise();
    users.findOrCreateByTwitterData(twitterUserData, promise);
    return promise;
})

文件中有什么？您可能需要调查Passport（）。它是everyauth的灵活替代品，everyauth不使用承诺，因此可能更容易在应用程序中调试。我是开发者，有任何问题都可以问我。
