For errors similar to: (this example uses php)
```bash
dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.62.dylib
  Referenced from: /usr/local/bin/php
  Reason: image not found
Abort trap: 6
```
then run
```bash
brew uninstall --ignore-dependencies php
brew install php
```
The issue _should_ now be resolved; however, you may need also run `brew link php`.
