Steps to reproduce or a small repository showing the problem:
typeorm migrations:generate -n test this create typecript file test.ts
typeorm migrations:run this fails with Unexpected token import

What solves the issue
Either call typeorm using ts-node, as explained here : #1561
Either transpile .ts file .js using typescript

Expected behaviour
Typeorm should be able to read the file it generated, which means : reading ts file or providing .js file
