I installed node using homebrew (Mojave), afterwards php stoped working and if I try to run
php -v I get this error:
dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.62.dylib
Referenced from: /usr/local/bin/php
Reason: image not found
I tried to uninstall both node and icu4c but the problem persists
Update - As stated in some of the comments, running
brew cleanupcould possibly fix this error, if that alone doesn't fix it, you might try upgrading individual packages or all your brew packages.
I just had this same problem. Upgrading Homebrew and then cleaning up worked for me. This error likely showed up for me because of a mismatch in package versions. None of the above solutions resolved my error, but running the following homebrew commands did.
Caution - This will upgrade all your brew packages, including, but not limited to PHP. If you only want to upgrade specific packages make sure to be specific.
brew upgrade icu4c
brew upgrade // or upgrade all packages
