It is a Lerna project. When I try to build the main package it throws the following exceptions:
Module parse failed: The keyword 'interface' is reserved (3:0)
> interface MyInterface {
...
Module parse failed: Unexpected token (1:7)
> export declare enum MyEnum {
These files are in one of the submodules.
