Błąd: moduł [$ injector: nomod] „ui.bootstrap” jest niedostępny! Błąd pisowni [...]

Mam tutaj ten problem i nadal nie mam spójnego rozwiązania tam szukającego. Prowadzę projekt Java z Angularem na frontendzie i próbuję zaimplementować funkcję autouzupełniania za pomocą ui-bootstrap, ale zawsze otrzymuję ten błąd.

Uncaught Error: [$injector:modulerr] Failed to instantiate module textChangrApp due to: Error: [$injector:modulerr] Failed to instantiate module ui.bootstrap due to: Error: [$injector:nomod] Module 'ui.bootstrap' 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.
