问题描述

我在我的项目上运行 tsc，我得到这些与 RxJS5 库相关的错误:

I run tsc on my project, and I get these errors relating to the RxJS5 lib:

有谁知道为什么会这样?这是我的 package.json 文件:

does anyone know why this is happening? this is my package.json file:

推荐答案

您需要将 "dom" 添加到 tsconfig.json 中的 lib 设置 文件的 compilerOptions:

You need to add "dom" to the lib setting in your tsconfig.json file's compilerOptions:

"lib": ["dom", "es2015"]

或者，您可以使用 skipLibCheck compilerOption 来避免检查 node_modules 中的 .d.ts 文件:

Alternatively, you can use the skipLibCheck compilerOption to avoid checking .d.ts files within node_modules:

"skipLibCheck": true

有关解释，请参阅此问题.

基本上，fromEvent 可观察工厂同时支持 Node 和 DOM 事件源，TypeScript 需要了解 DOM 类型.

Basically, the fromEvent observable factory supports both Node and DOM event sources and TypeScript needs to know about the DOM types.

这个 PR 应该可以解决问题.
