javascript - Mongo 错误：UnhandledPromiseRejectionWarning：MongoError：没有经过身份验证的用户

Question

为什么我会收到此错误。我在使用 macbook pro。在一个项目中工作，该项目有一个 node.js api 和 mongodb 数据库，其中 mongoose 作为 ODM 和一个快速服务器。我多次看到这个错误，不知道为什么会这样。有人有想法吗？希望得到一些帮助。

我试过的：卸载Mongodb，重新安装。擦除项目文件并重新克隆它们。擦拭我的 Mac（这有效，但当再次出现此错误时必须再次执行此操作）。也没有任何身份验证，所以它不应该要求它。

我还检查并确保我的代码没有未处理的承诺，我已经确认。
