**Do you want to request a *feature* or report a *bug*?** BUG **What is the current behavior?** ``` ENV NODE_ENV production ENV NODE_PATH /opt/app-node-modules ENV PATH $PATH:/opt/app-node-modules/.bin RUN yarn --no-emoji --modules-folder $NODE_PATH --pure-lockfile ``` `.bin` is nowhere to be found. **What is the expected behavior?** Behavior (as per yarn@0.24.4 and node@7.10.0) should be `.bin` folder at `/opt/app-node-modules/.bin` **Please mention your node.js, yarn and operating system version.** * node@8.4.0 * yarn@0.27.5 P.S. I see this behavior bumping our docker images to 8.4.0 from 7.10.0
