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:

$ tsc node_modules/rxjs/observable/FromEventObservable.d.ts(11,39): error TS2304: Cannot find name 'EventTarget'. node_modules/rxjs/observable/FromEventObservable.d.ts(11,103): error TS2304: Cannot find name 'NodeList'. node_modules/rxjs/observable/FromEventObservable.d.ts(11,114): error TS2304: Cannot find name 'HTMLCollection'. node_modules/rxjs/observable/dom/AjaxObservable.d.ts(16,23): error TS2304: Cannot find name 'XMLHttpRequest'. node_modules/rxjs/observable/dom/AjaxObservable.d.ts(77,59): error TS2304: Cannot find name 'Event'. node_modules/rxjs/observable/dom/AjaxObservable.d.ts(82,13): error TS2304: Cannot find name 'Event'. node_modules/rxjs/observable/dom/AjaxObservable.d.ts(97,20): error TS2304: Cannot find name 'Event'. node_modules/rxjs/observable/dom/AjaxObservable.d.ts(98,10): error TS2304: Cannot find name 'XMLHttpRequest'. node_modules/rxjs/observable/dom/AjaxObservable.d.ts(108,32): error TS2304: Cannot find name 'Event'. node_modules/rxjs/observable/dom/AjaxObservable.d.ts(108,44): error TS2304: Cannot find name 'XMLHttpRequest'. node_modules/rxjs/observable/dom/AjaxObservable.d.ts(119,10): error TS2304: Cannot find name 'XMLHttpRequest'. node_modules/rxjs/observable/dom/AjaxObservable.d.ts(128,39): error TS2304: Cannot find name 'XMLHttpRequest'. node_modules/rxjs/observable/dom/AjaxObservable.d.ts(136,22): error TS2304: Cannot find name 'XMLHttpRequest'. node_modules/rxjs/observable/dom/WebSocketSubject.d.ts(10,29): error TS2304: Cannot find name 'MessageEvent'. node_modules/rxjs/observable/dom/WebSocketSubject.d.ts(11,33): error TS2304: Cannot find name 'Event'. node_modules/rxjs/observable/dom/WebSocketSubject.d.ts(12,34): error TS2304: Cannot find name 'CloseEvent'. node_modules/rxjs/observable/dom/WebSocketSubject.d.ts(15,63): error TS2304: Cannot find name 'WebSocket'. node_modules/rxjs/observable/dom/WebSocketSubject.d.ts(27,13): error TS2304: Cannot find name 'WebSocket'. node_modules/rxjs/observable/dom/WebSocketSubject.d.ts(28,32): error TS2304: Cannot find name 'Event'. node_modules/rxjs/observable/dom/WebSocketSubject.d.ts(29,33): error TS2304: Cannot find name 'CloseEvent'. node_modules/rxjs/observable/dom/WebSocketSubject.d.ts(32,63): error TS2304: Cannot find name 'WebSocket'. node_modules/rxjs/observable/dom/WebSocketSubject.d.ts(36,23): error TS2304: Cannot find name 'MessageEvent'.

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:

{ "name": "oplog.rx", "version": "0.0.101", "description": "", "main": "index.js", "scripts": { "test": "suman test" }, "repository": { "type": "git", "url": "git+github/ORESoftware/oplog.rx.git" }, "keywords": [ "oplog", "mongodb", "rx", "rxjs" ], "author": "Olegzandr V.D.", "license": "MIT", "bugs": { "url": "github/ORESoftware/oplog.rx/issues" }, "homepage": "github/ORESoftware/oplog.rx#readme", "dependencies": { "bson": "^2.0.4", "json-stdio": "0.0.1016", "mongodb": "^3.0.4", "rxjs": "^5.5.7" }, "devDependencies": { "@types/mongodb": "^3.0.8" } }

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.
