Don't understand yarn check warnings

Question

When I ran yarn check , I received this warning:

  warning "\u001b[2mchokidar#\u001b[22mfsevents# node-pre-gyp@ ^0.6.29" could be deduped from "0.6.32" to " node-pre-gyp@0.6.32 " 

Can someone please help me figure this out?

• I do not know what the word deduped means.
• Why are there so many garbage characters in the warning message?
• What should I do to resolve this warning?

Thank you very much!
