bmleite has the correct answer about including the module.

If that is correct in your situation, you should also ensure that you are not redefining the modules in multiple files.

Remember:

angular.module('ModuleName', [])   // creates a module.

angular.module('ModuleName')       // gets you a pre-existing module.

So if you are extending a existing module, remember not to overwrite when trying to fetch it.

Make sure you are loading those modules  myApp services and myApp directives  as dependencies of your main app module  like this   angular module  myApp     myApp directives    myApp services       plunker  http   plnkr co edit wxuFx6qOMfbuwPq1HqeM p preview
