Angular2 RC definitions are not recognized by tsc

Currently, I am utilizing angular version 2.0.0-rc.1, however, I am encountering issues with the typescript compiler (Typescript version 1.8.10). Whenever I run tsc on my project, I am bombarded with numerous errors similar to this one:

app/app.component.ts(1,33): error TS2307: Cannot find module '@angular/core'

Nevertheless, I firmly believed that since the package.json in node_modules/@angular/core includes the line:

  "typings": "index.d.ts",

and index.d.ts contains the definitions, this issue should not persist. Interestingly, VSCode does not highlight any problems with these packages and successfully navigates to the source files when I click on "Go to Definition" for imports.

What steps can I take to prevent such compiler errors from occurring?

Update:

This is how my packages.json appears:

{
    "compilerOptions": {
        "module": "commonjs",
        "target": "es5",
        "sourceMap": true,
        "experimentalDecorators": true,
        "emitDecoratorMetadata": true,
        "noEmitHelpers": true,
        "noEmitOnError": true
    },
    "exclude": [
        "node_modules",
        "platforms"
    ]
}

To ensure smooth compilation in your TypeScript project, make sure to exclude the node_modules folder in your tsconfig.json.


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