I am puzzled about what steps to take next since the version of grunt I have is greater than what it's requesting. So far, I have performed the following actions:

  • npm cache clean
  • rm node_modules
  • re-install node/npm via nvm

My usage of nvm had caused issues previously when npm was not found, leading me to update without nvm. Eventually, I tried cleaning up and reinstalling using nvm - unsure if this might be causing the problem. Any guidance or advice on this matter would be highly appreciated. Thank you!

Answer №1

Encountering the dreaded ERR! issue during my npm install process on RHEL8.9. It seems that having multiple NPM versions and dependencies in one environment is causing this headache. I've already tried clearing out my NPM cache and deleting the node modules, but still no luck.
