Summary: The Circle CI iOS jobs are failing when installing Watchman: ``` #!/bin/bash --login -eo pipefail HOMEBREW_NO_AUTO_UPDATE=1 brew install watchman >/dev/null Error: The `brew link` step did not complete successfully Exited with code exit status 1 CircleCI received exit code 1 ``` The commit associated with the job where this issue first appeared did not make any changes to Watchman, but it did change the VM used by Circle CI for these jobs. Flushing the homebrew cache might help. ## Changelog  [INTERNAL] Pull Request resolved: #29843 Test Plan: Run on Circle CI. Watchman install step succeeded: https://circleci.com/gh/facebook/react-native/166160?utm_campaign=vcs-integration-link&utm_medium=referral&utm_source=github-build-link Reviewed By: fkgozali Differential Revision: D23495409 Pulled By: hramos fbshipit-source-id: 56a68bba3afc1350d4fc409d65f9229e3f38f467
