javascript - Sails.js - Node.js - [ReferenceError : Promise is not defined]

Question

我继承了一个用 Angular/Sails/PostgreSQL 开发的半完整项目(应用程序)

我以前没有 Angular、Sails.js 或 PostgreSQL 的经验

该应用程序已上线，目前正在运行，并且有几个重要用户正在使用它。

这个应用程序根本没有在登台运行，直到我执行“mkdir日志”，然后出现“ReferenceError:Promise未定义”，所以我认为该应用程序可能是在实时开发/实时配置的.

我已经设置了本地开发环境，并且也看到了此“ReferenceError”错误。

我怀疑配置问题是导致此问题的原因，但我不知道如果是这种情况我错过了什么。

我尝试过各种命令，例如“npm install”、“npm update”以及降级各种软件包，目前代码、package.json等是live的精确副本，并且模块应该完全相同版本。

我可以创建一个新的 sails 项目，在浏览器中查看时一切正常。

sails 升机壳输出:

我非常感谢对此的帮助。

info 不是您 passport.authenticate 行上的对象。

passport.authenticate('local', function(err, user, info) {

您记录了err和user，但您没有记录info - 如果您记录了info，您会已经看到 undefined 所以你不能在这一行使用它的 message 属性:

return res.send({
  message: info.message,
  user: user
});
