Error when use ngSemantic with Angular6

[longjingjun]

I follow the instruction to install ng-semantic. It is installed.

When I try to start the app using "ng serve", I got the following error:

ERROR in ./node_modules/ng-semantic/src/search/search.js Module not found: Error: Can't resolve 'rxjs/add/operator/debounceTime' in '/Users/user/Documents/Work/NodeJS_WorkSpace/LibraryManager/node_modules/ng-semantic/src/search' ERROR in ./node_modules/ng-semantic/src/search/search.js Module not found: Error: Can't resolve 'rxjs/add/operator/distinctUntilChanged' in '/Users/user/Documents/Work/NodeJS_WorkSpace/LibraryManager/node_modules/ng-semantic/src/search'

Here is my info:

` Angular CLI: 6.0.8 Node: 8.9.3 OS: darwin x64 Angular: 6.0.7 ... animations, common, compiler, compiler-cli, core, forms ... http, language-service, platform-browser ... platform-browser-dynamic, router
