错误：找不到模块 XXX（打字稿别名）

Question

It sounds like a common error. But in my case i can not find the reason. I am creating an NPM package as an backend-API for another project. I am using typescript and node.

I want to change my import statements from import XX from "../../../XXX" into import XX from "@XX" , am using PHP storm as code editor and it says that my code is good.

But when i run the script with npx npx ts-node src/index it will returns this:

 Error: Cannot find module '@authentication/SignUp' Require stack: - /Users/Youssef_1/Projects/driver-seat-amplify-api/src/index.js at Function.Module._resolveFilename (node:internal/modules/cjs/loader:933:15) at Function.Module._resolveFilename.sharedData.moduleResolveFilenameHook.installedValue [as _resolveFilename] (/Users/Youssef_1/Projects/driver-seat-amplify-api/node_modules/@cspotcode/source-map-support/source-map-support.js:679:30) at Function.Module._load (node:internal/modules/cjs/loader:778:27) at Module.require (node:internal/modules/cjs/loader:999:19) at require (node:internal/modules/cjs/helpers:102:18) at Object.<anonymous> (/Users/Youssef_1/Projects/driver-seat-amplify-api/src/index.js:6:18) at Module._compile (node:internal/modules/cjs/loader:1099:14) at Object.Module._extensions..js (node:internal/modules/cjs/loader:1153:10) at Module.load (node:internal/modules/cjs/loader:975:32) at Function.Module._load (node:internal/modules/cjs/loader:822:12) { code: 'MODULE_NOT_FOUND', requireStack: [ '/Users/Youssef_1/Projects/driver-seat-amplify-api/src/index.js' ] }

My mapping:

index.ts:

 import {SignUp, ConfirmSignUp, ResendSignUp} from "@authentication/SignUp"; import SignIn from "./Authentication/SignIn"; import Validator from "./Services/Validator"; import {RegexPatterns, RegexTypes} from "./Enums/Regex"; import SignOut from "./Authentication/SignOut"; import DeleteAccount from "./Authentication/DeleteAccount"; import UserManagement from "./Authentication/UserManagement"; import "./app.config"; export default { SignIn, SignUp, SignOut, ConfirmSignUp, ResendSignUp, Validator, UserManagement, RegexPatterns, RegexTypes, DeleteUser: DeleteAccount, }

tsconfig.json:

 { "compilerOptions": { "target": "esnext", "module": "commonjs", "strict": true, "esModuleInterop": true, "skipLibCheck": true, "moduleResolution": "node", "forceConsistentCasingInFileNames": true, "alwaysStrict": true, "baseUrl": "./src/", "sourceMap": true, "paths": { "@authentication/*": ["Authentication/*"] } } }

babel.config.js

 module.exports = { plugins: [ "@babel/plugin-transform-typescript", "@babel/preset-env", ["module-resolver", { "root": ["./src"], "alias": { "authentication": "./src/Authentication", } }] ], presets: [ "@babel/plugin-transform-typescript", "@babel/preset-env" ], };

Any ideas?

This saved my day: TS config path error. Error: Cannot find module '@/models/UserSchema' (accepted answer).

Installing ts-node fixed this issue for me.
