Hi,
It seems that an update has been made to the CircleCI images for node:8, and yarn is not available anymore. I get a /bin/bash: yarn: command not found
It doesn’t work with this image: circleci/node@sha256:940451eaef7c703182840ece520fb9f962dc0a64bce5d6cb4058a988de4eb236
It worked with this one: circleci/node@sha256:0abd249a8bcc6890d99dcd2cd348df0d428092913739b4771aa443e3d5021462
Best
David
