The latest version of this requires node 16 which I am not using. I ma trying to use react-markdown which seems to require this package

Expected behavior

it should compile fine

Actual behavior

./node_modules/mdast-util-to-hast/lib/index.js
Module not found: Can't resolve 'devlop' in '/home/user/my-app/node_modules/mdast-util-to-hast/lib'

Welcome @shorif2000! 👋
Sorry you ran into a spot of trouble.

react-markdown version 9 and it's dependencies require a minimum of node 16, node 12 is not supported.
I'd highly recommend upgrading your node version to 16 or higher, earlier node version are no longer supported nor receiving security updates.
If you do choose to stick with node 12, hold on react-markdown version 8 until you can upgrade both.
