Typescript 如何使类型在firebase云函数上工作？

类型脚本类型不适用于firebase管理员： 这是tsconfig.json文件：

"compilerOptions": {
    "lib": [
      "es6",
      "es2015.promise"
    ],
    "target": "es6",
    "module": "commonjs",
    "moduleResolution": "node",
    "jsx": "react",
    "outDir": ".",
    "rootDir": ".",
    "allowSyntheticDefaultImports": true,
    "noImplicitAny": true,
    "experimentalDecorators": true,
    "preserveConstEnums": true,
    "allowJs": true,
    "sourceMap": true,
    "strictNullChecks": true,
    "typeRoots": [          <------ // I tried to use typeRoots with @google-cloud
      "node_modules/@types"         // but it gives errors on tsc
    ]

---

在选择TypeScript作为语言时，我使用了firebase init的默认设置，一切正常。tsconfig.json中没有设置typeRoots属性。看起来是这样的：

{
  "compilerOptions": {
    "lib": ["es6"],
    "module": "commonjs",
    "noImplicitReturns": true,
    "outDir": "lib",
    "sourceMap": true,
    "target": "es6"
  },
  "compileOnSave": true,
  "include": [
    "src"
  ]
}

从这一点开始，逐步增加额外的东西，找出问题的根源

{
  "compilerOptions": {
    "lib": ["es6"],
    "module": "commonjs",
    "noImplicitReturns": true,
    "outDir": "lib",
    "sourceMap": true,
    "target": "es6"
  },
  "compileOnSave": true,
  "include": [
    "src"
  ]
}
