npx -y typescript@x tsc --noEmit prints no TS errors but did not typecheck at all

could not determine executable to run

Cause

The typescript package's bin is named tsc, not typescript, so npx cannot pick an executable. Grepping that output for error TS returns zero, which looks like a clean typecheck.

Fix

More npm errors
