tslint issues in MDB 5.2

I've migrated my project from MDB 4.3.7 to 5.2.0

I got more than 40 errors with tslint (npm run lint) on MDB components, something not seen in 4.3.

The first line "No valid rules have been specified" is puzzling.  I'm not sure if this triggers the rest.

I probe around but could not find any clues.
