A helper named 'basic-dropdown' could not be found

Using ember install ember-basic-dropdown will add the addon as devDependencies. Build works with no issues in my addon (incl. test/dummy app). Adding my addon to a consuming app and using my component which uses ember-basic-dropdown gives me A helper named 'basic-dropdown' could not be found

Moving ember-basic-dropdown to dependencies and the helper is resolvable but then inside my addon the build breaks with

Merge error: file ember-basic-dropdown.scss exists in /home/mike/projects/remerge/ember-remerge/tmp/broccoli_merge_trees-input_base_path-0wiZhWI4.tmp/1 and /home/mike/projects/remerge/ember-remerge/tmp/broccoli_merge_trees-input_base_path-0wiZhWI4.tmp/30
Pass option { overwrite: true } to mergeTrees in order to have the latter file win.

No in this case I was just using basic-dropdown. but This might be related:

I’ve created a new ember project and did

ember install ember-basic-dropdown

Just imagine you want a dropdown for now. And then later at some point:

ember install ember-power-select

And you will get this error. You have to remove basic-dropdown from your package.json. Might be worth mentioning in the docs

Miguel, actually I made it work by editing ember-cli-build.js and adding a line on it.

I have now other problems regarding power-datepicker but this is another forum.

Thanks
