javascript - 'jsonp' 未定义(带有 PubNub 的 AngluarJS)

Question

我正在学习 Angular 并使用 PubNub 库创建聊天应用程序，然后当我导航到可以创建房间或加入聊天的页面时出现此错误。

    TypeError: Cannot read property 'jsonp' of undefined

这不是什么意思，需要帮助吗？

jsonp 错误的原因是 Pubnub.init 有必需的选项参数

Pubnub.init({ publish_key: 'your pub key', subscribe_key: 'your sub key' });
