打字稿:重复标识符“IteratorResult" [英] TypeScript: Duplicate identifier 'IteratorResult'

问题描述

我正在尝试通过 tsc 进行编译——我已经在全球范围内安装了它——但出现错误:

I'm trying to compile via tsc--which I've installed globally--and I'm getting an error:

~/AppData/Roaming/nvm/v11.15.0/node_modules/typescript/lib/lib.es2015.iterable.d.ts:41:6 - error TS2300: Duplicate identifier 'IteratorResult'.

41 type IteratorResult<T, TReturn = any> = IteratorYieldResult<T> | IteratorReturnResult<TReturn>;
        ~~~~~~~~~~~~~~

  node_modules/@types/node/index.d.ts:170:11
    170 interface IteratorResult<T> { }
                  ~~~~~~~~~~~~~~
    'IteratorResult' was also declared here.

Found 2 errors.

我安装了 @types/node 版本 10.1.0.(@latest 有它自己的问题...)

I have @types/node version 10.1.0 installed. (@latest has its own issues...)

tsconfig.json

{
  "compilerOptions": {
    "target": "es2018",
    "moduleResolution": "node",
    "module": "commonjs",
    "jsx": "react",
    "lib": [
      "dom",
      "es2018",
      "dom.iterable",
      "scripthost"
    ],
    "typeRoots": [
      "./node_modules/@types",
      "./types"
    ],
    "types": [],

    "strictNullChecks": true,

    "noImplicitReturns": true,
    "noImplicitThis": true,

  },
  "files": [
    "app/index.tsx"
  ],
  "include": [
    "app/**/*.ts",
    "app/**/*.tsx",

    "test/**/*.tsx",
    "node_modules/@types/**/*.d.ts",
    "./types/**/*.d.ts"
  ],
  "exclude": [
    "dist"
  ]
}

如果我全局卸载 typescript 并运行 npx tsc 它可以工作，但是全局安装和运行 typescript 应该没有问题.毕竟，这就是全局安装东西的全部意义所在.

If I uninstall typescript globally and run npx tsc it works, but there should be nothing wrong with installing and running typescript globally. After all, that's the whole point of installing things globally.

与此同时，我有一个解决方法，就是给 tsc 取别名(我在 Windows 中使用 git bash).

In the meantime I have a workaround which is to just alias tsc (I'm using git bash in Windows).

alias tsc="path/to/project/node_modules/.bin/tsc.cmd"
