[Fixed] Library not loaded: /opt/homebrew/opt/icu4c/lib/libicui18n.73.dylib

I was getting the following error while running the expo tool for building an app on my MacBook Air.

dyld[17845]: Library not loaded: /opt/homebrew/opt/icu4c/lib/libicui18n.73.dylib

I tried many things and nothing worked.

Finally, upgrading the brew worked for me.

Note: Brew aka Homebrew is a package manager for MacOS and Linux systems. If you don’t have installed on your system, install it.

Run the following command.

brew upgrade

Remember it upgrades all the brew packages installed by Homebrew. So it will take some time to upgrade.

This command is handy for keeping your software up-to-date with the latest versions and security patches.

And then run the brew cleanup command.

brew cleanup

This command removes all the outdated versions of the packages and free up the disk space.

Hope this help you to solve the issue.
