typescript - Firebase 部署 - 找不到本地依赖项的模块

Question

我有一个名为 shared 的子模块，它位于 backend 文件夹(即云函数文件夹)旁边:

我在 backend/package.json 中添加了本地依赖 shared ，如下所示:

"dependencies": {
    ...
    "shared": "file:../shared"
}

我运行了 npm install 并确保 node_modules/shared 存在。虽然，当我运行以下代码时:

firebase deploy --only functions

我收到以下错误(来自 firebase):

Error: Error parsing triggers: Cannot find module 'shared/common'

Try running "npm install" in your functions directory before deploying.

这个错误是由于这一行:

import { currentWeek } from 'shared/common';

如果我将目录更改为 ../../../shared/common，firebase 将编译而不会出现任何错误。

共享/通用/index.ts:

export { currentWeek } from './current-week';

共享/tsconfig.json:

{
  "compilerOptions": {
    "baseUrl": ".",
    "target": "es5",
    "module": "commonjs",
    "declaration": true,
    "strict": true,
    "removeComments": true
  }
}

后端/tsconfig.json:

{
  "compilerOptions": {
    "baseUrl": ".",
    "declaration": true,
    "outDir": "./dist",
    "module": "commonjs",
    "noImplicitAny": false,
    "removeComments": true,
    "noLib": false,
    "allowSyntheticDefaultImports": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "resolveJsonModule": true,
    "target": "es6",
    "moduleResolution": "node",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2015",
      "dom"
    ]
  },
  "include": [
    "./src/**/*",
    "../shared/**/*"
  ]
}

如果我有这个模块，为什么会出现这个错误？有什么我想念的吗？

Answer 1

我认为，您必须为 typescript 编译器配置 module-resolution。

针对您的情况:

{
  "compilerOptions": {
    "baseUrl": ".", // This must be specified if "paths" is.
    "paths": {
      "shared/*": ["../shared/*"] // This mapping is relative to "baseUrl".
    }
  }
}

你可以用另一个名字命名shared。

{
      "compilerOptions": {
        "baseUrl": ".", // This must be specified if "paths" is.
        "paths": {
          "myLib/*": ["../shared/*"] // This mapping is relative to "baseUrl".
        }
      }
    }

用法:

import { currentWeek } from "myLib/common";
