在node.js中build立一个懒散的机器人，抛出一个我无法理解的错误。 有没有人见过这个？
我试图build立一个懒散的机器人，我遇到了一个我无法理解的错误。
这是错误的：
/Users/maecapozzi/Desktop/maebot/node_modules/vow/lib/vow.js:104 throw e; ^ Error: [Slack Bot Error] undefined at assert (/Users/maecapozzi/Desktop/maebot/node_modules/slackbots/libs/utils.js:15:15) at /Users/maecapozzi/Desktop/maebot/node_modules/slackbots/index.js:42:9 at Array.<anonymous> (/Users/maecapozzi/Desktop/maebot/node_modules/vow/lib/vow.js:712:56) at Immediate.callFns [as _onImmediate] (/Users/maecapozzi/Desktop/maebot/node_modules/vow/lib/vow.js:23:35) at tryOnImmediate (timers.js:534:15) at processImmediate [as _immediateCallback] (timers.js:514:5) 我也会和你分享我的代码，因为这应该有助于更好地理解发生的事情。
bot.js：
'use strict'; var MaeBot = require('../lib/maebot'); var token = process.env.BOT_API_KEY; var dbPath = process.env.BOT_DB_PATH; var name = process.env.BOT_NAME; var maebot = new MaeBot({ token: token, dbPath: dbPath, name: name }); maebot.run();

var pg = require('pg'); var connectionString = process.env.DATABASE_URL || 'postgres://localhost:5432/maebot'; var client = new pg.Client(connectionString); client.connect(); var query = client.query('CREATE TABLE dacts(id SERIAL PRIMARY KEY, text VARCHAR(40) not null)'); query.on('end', function() { client.end(); });
