Error: Could not resolve './directives/' from build\index.js

When running npm run build I am getting the following

It would seem it only likes flat file structures and not those build with directories.

In my src directory I have

Do I need the rollup-plugin-commonjs or rollup-plugin-node-resolve to resolve this? Any ideas?

Thanks Nicholas Irving

For those stumbling across this one. After spending way too long on the problem I realised it was an issue with the export. I had:

export * from './directory';

changed it to:

export * from './directory/index';

and the gulp tasks completed.

@gary-holland — Thank you for the update, much appreciated!
