打字稿没有从模块的 index.d.ts 中找到类型

Question

使用 Typescript 4.2.3，我正在从 Typescript 构建一个包。当我安装包时，它在node-moduleshas.js和.d.tsfiles 中的条目正如预期的那样。

??? dist
?   ??? index.d.ts
?   ??? index.js
?   ??? index.test.d.ts
?   ??? index.test.js
??? package.json

以下是内容package.json：

{
  "name": "postgres-base-class",
  "version": "0.1.3",
  "description": "Abstract class to handle an Postgres Client connection, provding execSql method to extending classes",
  "main": "dist/index.js",
  "types": "dist/index.d.ts",
  "devDependencies": {
<omitted>
  },
  "dependencies": {
    "pg": "^8.5.1"
  },
  "scripts": {
    "test": "jest",
    "prepack": "npm run clean && npm test && tsc --declaration",
    "clean": "tsc --build --clean"
  },
  "files": [
    "dist/"
  ],
  "author": "John Bito",
  "license": "UNLICENSED",
  "private": true
}

当我尝试扩展包中定义的类时，受保护方法的参数和返回类型any在VSCode中显示，并且tsc没有检测到错误参数。相反，它似乎将包视为没有类型的 JS 包。

我该怎么做才能使tsc安装包的位置可以使用包中的类型？

以下是内容index.d.ts：

??? dist
?   ??? index.d.ts
?   ??? index.js
?   ??? index.test.d.ts
?   ??? index.test.js
??? package.json

execSql导入包的方法的类型似乎是（根据VSCode）：

execSql(query: any): Promise<any>

也就是说的内容相匹配index.js所产生tsc（摘录）：

{
  "name": "postgres-base-class",
  "version": "0.1.3",
  "description": "Abstract class to handle an Postgres Client connection, provding execSql method to extending classes",
  "main": "dist/index.js",
  "types": "dist/index.d.ts",
  "devDependencies": {
<omitted>
  },
  "dependencies": {
    "pg": "^8.5.1"
  },
  "scripts": {
    "test": "jest",
    "prepack": "npm run clean && npm test && tsc --declaration",
    "clean": "tsc --build --clean"
  },
  "files": [
    "dist/"
  ],
  "author": "John Bito",
  "license": "UNLICENSED",
  "private": true
}

据我所见，依赖项pg的依赖项postgres-base-class被pg主项目的依赖项所掩盖。

• 如果您的主项目pg显式导入，请添加@types/pg到您的 main 的devDependencies.
• 如果没有，请确保pg不在主项目的依赖项中（以避免它遮蔽子项目的依赖项类型），并添加@types/pg到您的postgres-base-class[dev] 依赖项
