@types/core-js errors when added as dependency to Angular-Cli (1.5.0) + Electron

[flamusdiu]

Case

BUG

Issue

ERRORS WHEN TRYING TO BUILD USING GULP 4.0 TASK INSIDE AN ANGULAR-CLI (1.5.0) PROJECT AND ELECTRON. THE ERRORS HAPPEN WHEN YOU ADD RXDB AS A DEPENDENCY BEFORE YOU IMPORT IT INTO THE PROJECT.

POSSIBLE RELATED ISSUE DefinitelyTyped/DefinitelyTyped#15410. NOTHING IN THAT ISSUE SEEMS RESOLVE THE ISSUE WHEN MODIFYING THE tsconfig.json file.

Info

• Environment: (Node.js/browser/electron/etc.)
  NODEJS/ELECTRON
• Adapter: (IndexedDB/Localstorage/LevelDB/etc.)
  LEVELDB

Code

GULP TASK (SNIPPED FROM gulp.babel.js):

import typescript from 'gulp-typescript';
import gulp from 'gulp';

const path = {    
    scripts: {
        electron:'src/electron/**/*.ts',
        electronApp: 'dist/electron-app.js',
        dest: 'dist/'
    }
};

function buildElectron() {
    return gulp.src(path.scripts.electron)
        .pipe(typescript())
        .pipe(gulp.dest(path.scripts.dest));
}

Oops ... I had to pull in the tsconfig.json through creating a tsProject from gulp-typescript =\
