Project Folders Structure

my tsconfig.json:

{
  "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

You have the error since the TypeScript compiler can't find the core.d.ts file. You need to have the following configuration to make it work. Be careful to the moduleResolution attribute that must be set to 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"
  ]
}
