I'm facing this problem to start the Angular 6 app. Does anyone have solution to this?

```
ERROR in node_modules/rxjs/internal/types.d.ts(81,44): error TS1005: ';' expected.
node_modules/rxjs/internal/types.d.ts(81,74): error TS1005: ';' expected.
node_modules/rxjs/internal/types.d.ts(81,77): error TS1109: Expression expected.

```

Tried a lot to solve this. Tried to install different versions of Node/RxJS as well. Yet no luck.
