This repo is to demonstrate Yarn issue #616 affecting v0.15.1 that I have experienced running Node v6.2.0 on Mac OSX 10.11.5. When using yarn to install dependencies into an uncreated node_modules folder, the bower_components folder is emptied out.

Steps to Reproduce

• clone this repo to your machine
• bower install - the bower_components folder should be created with a single bourbon folder
• yarn - the node_modules folder should be created with a single wrappy folder, but the bower_components folder will now be empty
