dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.62.dylib

I keep getting this, first in Ruby, so had to re-install Ruby 2.3.3. Now node.

Robs-iMac:something roblacey$ node -v
dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.62.dylib
  Referenced from: /usr/local/bin/node
  Reason: image not found
Abort trap: 6

I must have installed something that played havoc with this lib.

Robs-iMac:something roblacey$ brew reinstall node
