markdown php：未加载库：/usr/local/opt/icu4c/lib/libicui18n.61.dylib

Posted 2021-05-05

After upgrading to Node v.10.9.0 via Homebrew the following error message was thrown from PHP:

```
dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.61.dylib
  Referenced from: /usr/local/bin/php
  Reason: image not found
```

Reinstall PHP to fix, for me that's:

`brew reinstall php@7.1`
