如何在Nest.js配置中使用ES2022

Question

我正在尝试让 Nest.JS 项目使用 ES2022，因为我正在尝试使用 ES 模块包。我已经更新了

tsconfig.json

和

paackage.json

但它不起作用，因为它不断出现此错误。

node:internal/modules/esm/resolve:257
    throw new ERR_MODULE_NOT_FOUND(
          ^

Error [ERR_MODULE_NOT_FOUND]: Cannot find module 'C:\Users\CodeGhinux\Desktop\project\Forked\project-core\dist\src\app.module' imported from C:\Users\CodeGhinux\Desktop\project\Forked\project-core\dist\src\main.js

  code: 'ERR_MODULE_NOT_FOUND',
  url: 'file:///C:/Users/CodeGhinux/Desktop/project/Forked/project-core/dist/src/app.module'
}

Node.js v22.8.0
[11:46:59] Found 0 errors. Watching for file changes.

我还在

"type": "module"

中添加了

package.json

并更新了我的

tsconfig.json

以包含 ES2022 模块。我也尝试过使用

EsNext

，但它仍然给出相同的错误。

这是我现在的

tsconfig.json

{
  "compilerOptions": {
    "module": "ES2022",
    "moduleResolution": "bundler",
    "declaration": true,
    "removeComments": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "allowSyntheticDefaultImports": true,
    "target": "ES2022",
    "sourceMap": true,
    "outDir": "./dist",
    "baseUrl": "./",
    "incremental": true,
    "skipLibCheck": true,
    "strictNullChecks": false,
    "noImplicitAny": false,
    "strictBindCallApply": false,
    "forceConsistentCasingInFileNames": false,
    "noFallthroughCasesInSwitch": false,
    "esModuleInterop": true,
    "lib": ["ES2022"]
  },
  "exclude": ["node_modules"],
  "include": ["src/**/*.ts", "bin/*.ts"]
}

导入语句的相对说明符必须使用文件扩展名：https://nodejs.org/api/esm.html#esm_import_specifiers

只是

import {HelloWorld} from "./HelloWorld.js"

； TypeScript 足够聪明，可以在编译期间找出你想要的 HelloWorld.ts。

解决方法可能是https://www.npmjs.com/package/tsc-alias，如https://stackoverflow.com/a/76678279/517319
