Does bower need to be in your npm dependencies for this to work? I'm still seeing the same issue:

@danielberkompas how this works is it checks if a bower.json file exists in your repo's root directory. If there is a bower.json, it will attempt to do bower install. bower install will only work if it was installed via npm.

So yes, you will need to add bower as one of of your npm dependencies. I could probably have it auto-install bower if it detects a bower.json file. But it's also nice to explicitly set it as a dep in npm. What do you think?

It makes sense. Added it to my devDependencies, and the buildpack works fine.
