帆 对不起，这个函数不知道如何处理 {...} 回调

Question

不知何故，我的sails.js 1.x 环境已经受到破坏，以至于我不再能够对我的PostgreSQL 数据库进行本机查询。我确定问题出在某个包的版本上，因为我在周末对 NodeJS 9 进行了一些实验，但这段代码在周五工作，我看不到问题所在。有什么建议吗？

sails> sails.getDatastore().sendNativeQuery('SELECT COUNT(*) FROM "user"').then(console.log);
Promise {
  _bitField: 0,
  _fulfillmentHandler0: undefined,
  _rejectionHandler0: undefined,
  _promise0: undefined,
  _receiver0: undefined }

sails> UsageError: Sorry, this function doesn't know how to handle {...} callbacks.
If provided, the 2nd argument should be a function like `function(err,result){...}`
|  If you passed in {...} on purpose as a "switchback" (dictionary of callbacks),
|  please be aware that, as of machine v15, you can no longer pass in a switchback
|  as the 2nd argument.  And you can't pass a switchback in to .exec() anymore either.
|  Instead, you'll need to explicitly call .switch().

任何提示或想法都会非常受欢迎。

Answer 1

这原来是我们正在运行的 Sails 版本中的一个错误。我将sails 升级到1.0.2 并解决了。
