I gave up and just went ahead with local hombrew. Its not great, but feel free to grab my ci_post_clone.sh script. Note that this overwrites .xcode.env so if you have anything in there besides your NODE_BINARY path you'll need to adjust accordingly. #!/bin/zsh set -e export CI_SCRIPTS_DIR=${PWD} export RN_DIR=${PWD}/../../ export RN_IOS_DIR=${PWD}/../ export BREW_DIR=${CI_DERIVED_DATA_PATH}/opt/hombrew echo "*** Date: $(date)" echo "*** Running post clone script in: ${PWD}.
