TypeScript + Playwright Error: Cannot find module

I ran into a problem coding test automation with playwright. When running the test, the following error occurs at test.spec.ts:

Error: Cannot find module '@common/common' code: 'MODULE_NOT_FOUND'

How to solve this problem?

there are codes below

test.spec.ts

import { chromium, ChromiumBrowser, Page } from "playwright";
import { test, expect, PlaywrightTestConfig } from "@playwright/test";
import Common from "@common/common";

test.beforeAll(async ({ page }) => {

});

test.describe('Go test', () => {
  test('Test1', async ({ page }) => {
    console.log("1111111111");
  });
})

package.json

{
  "name": "type-sanity",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "ts-node -r tsconfig-paths/register src/main.ts",
    "test": "npx playwright test"
  },

    "ts-node": "^10.1.0",
    "tsconfig-paths": "^3.10.1",
    "typescript-module-alias": "^1.0.2"
  }
}

@playwright/test does not consider your tsconfig.json when transpiling your TS files (thats why your custom path mapping is not working). You can transpile your TypeScript manually, see here: https://playwright.dev/docs/test-typescript

For further reference see this upstream issue: https://github.com/microsoft/playwright/issues/7121
