Compile error after install

After installing 4.3.2, I get this error in my app.module: error TS2307: Cannot finde module 'angular-bootstrap-md' even though the folder exists.
I found this post which seemed to be solving the same symptom, but I have not figured out how to add 'Include' to the compile options: https://stackoverflow.com/questions/48769649/add-mdbootstrap-to-an-angular-project
