What is meaning of error: Uncaught Error: [$injector:nomod] - angularjs

Question

I have this error:
Uncaught Error: [$injector:nomod] http://errors.angularjs.org/1.3.15/$injector/nomod?p0=sensorManagement
sensorManagement is my module name.
Any idea what the error above mean?

Answer 1

If you follow the link you'll see:
Module 'sensorManagement' is not available! You either misspelled the
module name or forgot to load it. If registering a module ensure that
you specify the dependencies as the second argument.
That means you did not declare the module, which you can fix like so:
angular.module('sensorManagement', []);
It's also possible that you have the problem as answered by Amo_Geismar, and you have the above multiple times (or forgot to load the js file).
To work with a module after declaring it, you leave out the array.
sensorManagement.module.js
angular.module('sensorManagement', []);
someService.service.js
angular.module('sensorManagement') // Notice the lack of ', []' here
.factory('yourService', function() {
// Code here...
});

Answer 2

possible causes:
1) In essence you are creating the same module more than once.
I think you probably have this somewhere in your code multiple times:
angular.module('sensorManagement',[])
if you want to use the module do
angular.module('sensorManagement'). //chain whatever controller/filter/service/factory
2) you have forgotten to load the script where you declared the module so probably in your index.html you are missing
<script src="your/modules/sensorManagement.js"/>
which would contain your declaration:
angular.module('sensorManagement',[])
