javascript - 安装本地 Node 类型时出现重复标识符

Question

我尝试在项目上运行 tsc，但收到一条错误消息，指出有两个重复的标识符 URL 和 URLSearchParams .

我在全局范围内安装了 typescript ，并且在我的项目中我有@types/node。

但是，当我在项目中安装 @types/node 时，我收到此错误:

../../../../../.nvm/versions/node/v10.0.0/lib/node_modules/typescript/lib/lib.es2016.full.d.ts(13404,11): error TS2300: Duplicate identifier 'URL'.

node_modules/@types/node/index.d.ts(2417,14): error TS2661: Cannot export 'URL'. Only local declarations can be exported from a module.
node_modules/@types/node/index.d.ts(2417,19): error TS2661: Cannot export 'URLSearchParams'. Only local declarations can be exported from a module.

不确定出了什么问题以及为什么会收到此错误。

如果我从项目中删除 Node 类型，我会在其他依赖项中收到错误，指出它找不到net、http等:

node_modules/@types/uuid/interfaces.d.ts(1,23): error TS2688: Cannot find type definition file for 'node'.
node_modules/@types/uuid/interfaces.d.ts(4,48): error TS2304: Cannot find name 'Buffer'.
node_modules/@types/uws/index.d.ts(7,23): error TS2688: Cannot find type definition file for 'node'.
node_modules/@types/uws/index.d.ts(10,23): error TS2307: Cannot find module 'http'.
node_modules/@types/uws/index.d.ts(11,24): error TS2307: Cannot find module 'https'.
node_modules/@types/uws/index.d.ts(12,22): error TS2307: Cannot find module 'net'.

tsconfig.json

{
  "compilerOptions": {
    "target": "es2016",
    "module": "system",
    "strict": true,
    "outFile": "../../lib/client/red5.js",
    "sourceMap": true,
    "declaration": true
  },
  "include": [
    "./Connector.ts",
    "**/*.ts"
  ]
}

package.json中的依赖项

"dependencies": {
  "@types/get-port": "^3.2.0",
  "@types/node": "^10.0.0",
  "@types/uuid": "^3.4.3",
  "@types/uws": "^0.13.2",
  "get-port": "^3.2.0",
  "uuid": "^3.2.1",
  "uws": "^9.148.0"
},
"devDependencies": {
  "uglify-es": "^3.3.9"
}

如 Node.js 10 变更日志中所述，URL 和 URLSearchParams 现在可在全局范围内使用，以模拟浏览器中的环境:

所以我敢打赌，类型定义@types/node尚未更新，无法正确考虑此更改。
