@tomwayson I had to pull master to merge your fix. And, then I updated karma-typescript and typescript to latest. Now everything is running correctly on my local machine.

Here's my package.json:

  "devDependencies": {
    "@types/jasmine": "^2.8.11",
    "concurrently": "^3.4.0",
    "jasmine-core": "^2.8.0",
    "karma": "^6.3.16",
    "karma-chrome-launcher": "^2.0.0",
    "karma-coverage": "^1.1.2",
    "karma-firefox-launcher": "^1.1.0",
    "karma-jasmine": "^1.1.0",
    "karma-mocha-reporter": "^2.2.3",
    "karma-typescript": "^5.5.3", <== this is updated
    "mkdirp": "^0.5.1",
    "onchange": "^3.2.1",
    "rimraf": "^2.6.2",
    "rollup": "^0.41.6",
    "rollup-plugin-uglify": "^2.0.1",
    "tslint": "^5.7.0",
