The attribute 'map' is not found on the data type 'Observable<[{}, {}]>'

Struggling to incorporate map, PublishReplay, and other rxjs functions into Angular6, I keep encountering a compilation error stating "Property 'map' does not exist on type 'Observable<[{}, {}]>'" every time. The same issue arises when attempting to use the other rxjs features.

I've attempted:

importing map, installing rxjs-compat, and editing tsconfig.json

  unifiedSearch: Function = (query: string): Observable<UnifiedSearch> => {
    return forkJoin(
      this.searchService.gitSearch(query),
      this.codeSearchService.codeSearch(query)
    ).map((response :[GitSearch,GitCodeSearch]) => {
      return {
        respositories: response[0],
        code: response[1]
      };
    });
  };

When trying to implement it using "pipes," an error is thrown saying map cannot be found.

 unifiedSearch: Function = (query: string): Observable<UnifiedSearch> => {
    return forkJoin(
      this.searchService.gitSearch(query),
      this.codeSearchService.codeSearch(query)
    ).pipe(map((response :[GitSearch,GitCodeSearch]) => {
      return {
        respositories: response[0],
        code: response[1]
      };
    }));
  };

Ensure that you are importing the map function in the following way -

import { map } from 'rxjs/operators';

Also, remember to use the pipe method.
