TypeScript 错误：重复的标识符“LibraryManagedAttributes”

Question

编译失败。

/moonholdings.io/node_modules/@types/react-dom/node_modules/@types/react/index.d.ts (2312,14)：重复的标识符“LibraryManagedAttributes”。

不知道为什么我会得到这个。

我已经将我的等级"@types/node"从 10 降到了 8，但这不起作用。也尝试过"@types/node": "^9.6.7"

我的仓库： https: //github.com/Futuratum/moonholdings.io

我的package.json

{
  "name": "moonholdings.io",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "build-css": "node-sass-chokidar src/ -o src/ --source-map",
    "watch-css": "npm run build-css && node-sass-chokidar src/ -o src/ --watch --recursive --source-map",
    "start": "react-scripts-ts start",
    "build": "react-scripts-ts build",

  },

    "@types/node": "^8.10.29",
    "@types/react-dom": "^16.0.7",
    "typescript": "^3.0.3"
  }
}

这是我的 tsconfig

Answer 1

您可能会发现重复项位于node_modules/@types/react和node_modules/types/react-dom/@types/react/或类似的设置中，其中一个包对另一个包具有嵌套依赖关系。

一起卸载并重新安装 @types/react-dom 和 @types/react 为我解决了这个问题。

yarn remove @types/react-dom @types/react


yarn add -D @types/react-dom @types/react

Answer 2

我仍然不确定是什么导致了这个错误，但是我已经检查了我的应用程序的早期版本，它是稳定的。因此将从那里继续工作。

这是工作的 package.json

{
  "name": "moonholdings.io",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "start": "react-scripts-ts start",
    "build": "react-scripts-ts build",
    "test": "react-scripts-ts test --env=jsdom",
    "eject": "react-scripts-ts eject"
  },
  "dependencies": {
    "@types/jest": "^23.3.1",
    "@types/node": "^10.9.4",
    "@types/react": "^16.4.13",
    "@types/react-dom": "^16.0.7",
    "react": "^16.4.2",
    "react-dom": "^16.4.2",
    "react-ts-with-scss": "2.1.0",
    "typescript": "^3.0.3"
  },
  "devDependencies": {}
