i did the steps that i said before to run my project, but i don't know whats going on here now? i also did rm -rf node_modules, rm package-lock.json, npm cache clean --force and used npm install again but it's still not working!

Answer 1

Add --unsafe-perm flag while installing

For linux/mac

sudo npm install --unsafe-perm -g node-sass

For windows environment , hit same command removing sudo
