Unable to change the directory for angular2/core - having issues with updating

Whenever I include the following code in my app.component.ts:

import {Component} from 'angular2/core';

My application runs successfully, but the compiler throws an error saying Error:(1, 25) TS2307: Cannot find module 'angular2/core', even though the core file is located in the node_modules/angular2/core directory!

If I change the core directory, my app stops working, but the compiler works fine! I am currently following the ANGULAR: 5 MIN QUICKSTART.

You can view the project folders structure here.

This is what my tsconfig.json looks like:

{
  "compilerOptions": {
    "target": "es6",
    "module": "system",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false
  },
  "exclude": [
    "node_modules",
    "typings/main",
    "typings/main.d.ts"
  ]
}

Answer №1

The issue you're facing is due to the fact that the TypeScript compiler cannot locate the core.d.ts file. In order to resolve this, it's essential to configure the following settings properly. Pay close attention to the moduleResolution attribute which should be configured as node:

{
  "compilerOptions": {
    "target": "es5",
    "module": "system",
    "moduleResolution": "node", // <----------
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false
  },
  "exclude": [
    "node_modules",
    "typings/main",
    "typings/main.d.ts"
  ]
}
