[Solved] RC2: Error Cannot write file `component.d.ts` because it would overwrite input file

After upgrading to RC2, i did

rm -rf .tmp
rm -rf node_modules
npm install

Project is working fine in browser with ionic serve
But when I do ionic run android to run in device, I get following errors:

Pls help

Removing all *.d.ts files helped.
compileOnSave was set to false in tsconfig.ts, but still declarations got generated somehow.

Ran this command from src/

find . -type f -name "*.d.ts" -delete
