I’m on Fuse 1.1.0, and macOS Sierra 10.12.5.

I am trying to use InterApp module,

```auto
var Observable = require("FuseJS/Observable");
var InterApp = require("FuseJS/InterApp");

InterApp.on("receivedUri", function(uri) {
    console.log("Launched with URI", uri);
});
url = Observable("http://localhost:3000");

```

but it makes some weird error - cannot find FuseJS module,

```auto
Error: : Error message: require(): module not found: FuseJS/InterApp
 in Fuse.Reactive.JavaScript.DiagnosticSubject

```

I already embed them and there is no problem when I just remove the InterApp instance.

This is my unopj code

```auto
{
  "RootNamespace":"",
  "Packages": [
    "Fuse",
    "FuseJS",
    "Fuse.Launcher"
  ],
  "Includes": [
    "*",
    "Modules/*.js:Bundle"
  ],
  "Mobile": {
  "UriScheme": "GoToMariazu",
  "ShowStatusbar": false,
  "Orientations": "Portrait"
  }
}

```

Is there any problem on my code…? I cannot understand that FuseJS make some error only when I use InterApp module.

After you make changes to your `.unoproj` file, you need to run `uno clean` command in Terminal, in your project root folder. Followed by a rebuild of the project. Linked libraries need to be compiled into the source the first time you refer to them.
