When I have typescript globally only, I get:
Running 'build:before' npm script before build
> saveup@ build /Users/user/project
> ionic-app-scripts build
module.js:442
throw err;
^
Error: Cannot find module 'typescript'

Why the sudden move from global to local typescript and how to mitigate above error?
