I'm trying to do npm install and an error appears :
Failed at the node-sass@4.5.0 postinstall script.
I tried to delete node_modules and then reinstall it, same error appears.
what will be the solution?
node v8.9.3
npm v5.4.2
ionic 3.19.0
Got the same problem (node v10.3.0, ionic 3.13.0). This worked :
package-lock.json,node_modules folder, npm install again.try
sudo rm -rf package-lock.json node_modules
sudo npm cache clean --force
npm i --unsafe-perm node-sass
Just Try with this command hope it will very helpful. it's working for me
sudo npm install -g node-sass@4.5.0 --unsafe-perm=true --allow-root
