npm install -> Failed at the node-sass@4.9.3 postinstall script

August 11, 2022

I’m trying to do npm install and an error appears :

Failed at the node-sass@4.9.3 postinstall script.

npm : 6.14.11

node : 16.15.0

I tried to delete node_modules and then reinstall it, same error appears. what will be the solution?

I clean the cache with : npm cache clean --force
I delete the package-lock.json

I have uninstall et reinstall multiple time. I restart the computer.

I don’t know what to do …

Thanks in advance for your help
