Question

我试图在我的Node JS打字稿应用程序中使用validator.ts进行验证。我跑了命令，

npm install validator.ts --save

并安装它。现在，当我运行gulp来构建我的应用程序时，它会在validator.ts文件中抛出以下错误。

我在这里做错了什么？请指教。

我看到了一些类似的问题，并将以下几行附加到我正在验证的主要课程中。但它仍然无济于事。

/// <reference path="../../node_modules/class-validator/Validator.d.ts"/>
/// <reference path="../../node_modules/class-validator/index.d.ts"/>

我希望你不介意我把它作为一个答案，因为不幸的是，这似乎是最终的。

发生此错误是因为您尝试定位ES5并且未定义Promise接口。它在the .d.ts file typescript uses for es6中定义。

Validator.ts明确指出使用ES6功能。你在评论中提到你不能以ES6为目标。

您选择我的方式：

目标ES6。注意，这并不意味着你被困在那里，见选项4。
请勿使用Validator.ts
按照Validator.ts npm page
使用类似babel的转换器来自Typescript＆gt; ES6＆gt; ES5。

Validator.ts文件抛出错误，说“无法找到承诺”
