This has been fixed:

  • delete node_modules
  • reinstall everything

(You might also need to delete yarn.lock and/or package-lock.json to ensure that cached modules are not used.)

I ran these commands:

  • rm -rf node_modules
  • npm cache clear --force
  • yarn cache clean
  • yarn
    still the same problem when i run yarn serve

This was resolved, it is confirmed to be resolved. Make sure that all copies of regex-not are 1.0.2 (not 1.0.1)

Thank you. The one step I missed was deleting the yarn.lock file before running yarn again. That fixed the issue.

good suggestion. I'll add a suggestion to delete that and package-lock.json to the fix.
