If you have recently upgraded your MacOS operating system, you may get the following error in your terminal when installing some Homebrew packages:
Error: Permission denied @ apply2files - /usr/local/lib/node_modules/expo-cli/node_modules/.bin/detect-libc
How to solve the Permissions Denied problem
Simply run the following command in your terminal:
sudo chown -R $(whoami):admin /usr/local/* \
&& sudo chmod -R g+rwx /usr/local/*
Or change the user directly:
sudo chown -R ${LOGNAME}:staff /usr/local/lib/node_modules
