我正在尝试将 Bluebird 与 Seneca 一起使用，以保证我创建的所有 seneca 模块。我希望能够链接 seneca 命令。

这是一个事务模块，它使事情尽可能简单，只有一个任务，创建一个事务

// ./app/transaction.js

module.exports = function(options) {
  var Promise = require('bluebird');
  var seneca = this;
  var act = Promise.promisify(seneca.act, {context: seneca});

  var Transaction = require('./models/transaction');

  this.add({role:'transaction', cmd: 'create'}, function( msg, done ) {
    var t = new Transaction({
      datetime: new Date(),
      stylist_ids: ["STY_001", "STY_002"],
      promoter_ids: ["HOT_001", "HOT_002"],
      amount: 100
    });

    t.save((err,transaction) => {
      if (err)
        done(err);
      else
        done(null, { transaction: transaction });
    });
  })
}

这是我的 server.js 代码，目前应该只使用 seneca 命令创建一个事务：

// server.js

var mongoose = require('mongoose');
mongoose.connect("mongodb://localhost:27017/promisfy");

var seneca = require('seneca')();
var Promise = require('bluebird');
var act = Promise.promisify(seneca.act, seneca);

var transaction = require ('./app/transaction');
seneca.use(transaction);

act({role:'transaction', cmd: 'create'})
  .then(function (result) {
    console.log(result)
  })
  .catch(function (err) {
    console.log(err)
  });

但我得到这个错误：

    at run (bootstrap_node.js:418:7)
    at startup (bootstrap_node.js:139:9)

任何帮助表示赞赏。谢谢 ：）

“请注意，Bluebird v3 有一些承诺 API 更改。而不是

var act = Promise.promisify(seneca.act, seneca);

我们必须使用

var act = Promise.promisify(seneca.act, {context: seneca});"

server.js 有旧命令 -_-''
