Errors when transpiling ts files for an Angular2 application

I try to use TypeScript with Angular. For this, I transpile my ts files using the tsc command and I have some errors. That said, the files are actually transpiled into JavaScript and I can make work my application but these errors are a bit strange....

Here is what I have:

app.ts(1,1): error TS1148: Cannot compile modules unless the '--module' flag is provided.
app.ts(1,42): error TS2307: Cannot find module 'angular2/angular2'.
app.ts(13,7): error TS1219: Experimental support for decorators is a feature that is subject to change in a future release. Specify '--experimentalDecorators' to remove this warning.

Here is the content of the tsd.json file:

{
  "version": "v4",
  "repo": "borisyankov/DefinitelyTyped",
  "ref": "master",
  "path": "typings",
  "bundle": "typings/tsd.d.ts",
  "installed": {
    "angular2/angular2.d.ts": {
      "commit": "78ba6e41543e5ababbd1dda19797601be3c1f304"
    }
  }
}

Here is the content of the tsdconfig.json file:

{
  "compilerOptions" : {
    "emitDecoratorMetadata": true,
    "module": "commonjs",
    "target": "es5"
  },
  "files" : [
    "app.ts",
    "typings/angular2/angular2.d.ts"
  ]
}

To compile, I execute the command: tsc --watch *.ts. My ts files are located at the root of my project.

Thanks very much for your help, Thierry

First, if you specify file(s) in tsc command, tsconfig.json file is ignored. You can learn more about it here. So you should invoke command: tsc -w. Second, you do not have to include typings in your files, they are just for intellisense in your editor(and angular2 includes its typings by default).
