Definitelytyped: @types/core-js 与 typescript/lib/lib.es6.d.ts 冲突，当 @types/core-js 没有实际使用时

创建于 2016-10-04 · 12评论 · 资料来源: DefinitelyTyped/DefinitelyTyped

一个简单的重现仓库： https : npm i && npm run build ，错误是：

node_modules/@types/core-js/index.d.ts(21,14): error TS2300: Duplicate identifier 'PropertyKey'.
node_modules/typescript/lib/lib.es6.d.ts(4133,14): error TS2300: Duplicate identifier 'PropertyKey'.

预期：没有错误，因为app.ts是空的。 @types/core-js用于static/app.ts 。

  "devDependencies": {
    "@types/core-js": "^0.9.34",
    "core-js": "^2.4.1",
    "typescript": "^2.0.3"
  }

有类似的问题。在我的tsconfig.json添加了"skipLibCheck": true到compilerOptions tsconfig.json并且有所帮助

需要 lib.es6 中未包含的 core-js 的哪些部分？你不能简单地不安装@types/core-js吗？

aciccarello 于 2016-10-06

@aciccarello core-js 和 @types/core-js 由前端在static/app.ts ，这部分运行良好

有 2 个tsconfig.json ，一个用于后端（es6，这里发生错误），另一个用于前端（es5，没有错误，效果很好），

@plantain-00 你发现了吗？
我有一个类似的问题，我想使用 core-js（字典）的一些非标准功能，但类型与 typescripts 库冲突。

jefbarn 于 2016-10-17

@jefbarn对于非标准功能，我没有解决方案。
对于标准功能，我卸载了@types/core-js ，并删除了import "core-js"; ，因为 core-js 是 ES2015+ 的 polyfills，所以我可以使用typescript/lib/lib.es6.d.ts代替， tsconfig.json好像：

{
    "compilerOptions": {
        "module": "commonjs",
        "target": "es5",
        "lib": [
            "es2015",
            "es5",
            "dom",
            "scripthost"
        ]
    }
}

看来这个问题还是需要的，我重新打开这个。

我在使用@types\core-js并针对 ES6 时遇到了这个问题

anorborg 于 2016-11-02

@anorborg我确实使用这样的方法解决了我的情况：

  "compilerOptions": {
    "module": "commonjs",
    "target": "es6",
    "moduleResolution": "node",
    "lib": ["es5", "dom"],
    ...
  }

@jefbarn确实有效。基本上core-js和 typescript 2.x es6.d.ts库是冲突的，这告诉打字稿不要使用它的es6.d.ts 。我_认为_更_纯_的解决方案是为core-js （即core-js-es6-object ）创建一些模块类型定义，而不是包括整个core-js定义。我试图在本地启动它，但无法让本地自定义类型工作。如果我有时间，我会尝试弄清楚并为所有模块创建 PR。

引起注意。

我刚刚使用这个 ts 配置用tsc 2.2.0创建了一个新项目：

{
  "compilerOptions": {
    "outDir": "./build/",
    "rootDir": "./src/",
    "baseUrl": ".",
    "sourceMap": true,
    "noImplicitAny": false,
    "module": "commonjs",
    "target": "es6"
  },
  "include": [
    "./src/**/*.ts"
  ],
  "compileOnSave": false
}

这会产生这些错误：

将目标更改为es5导致干净的构建。

我不确定这个问题是如何引起如此少的关注；肯定很多人都试图用 TS 来瞄准 ES6 并且也会遇到这个问题？

@wyqydsyq core.js 和 ES6 都定义了很多相同的定义。要么不包含@types/core.js 要么在你的 tsconfig 中设置 "lib": ["es5", "dom"]
