Unknown provider: $modalProvider <- $modal error with AngularJS

Question

I keep receiving this error as I\'m trying to implement bootstrap Modal window. What could be the cause of it? I\'ve copy/pasted everything from http://angular-ui.github.io/

5 years later (this would not have been the problem at the time):

The namespacing has changed - you may stumble across this message after upgrading to a newer version of bootstrap-ui; you need to refer to $uibModal & $uibModalInstance.
