Short description of the problem:

Running the following tweet in my app folder, I got an error and my app doesn't work anymore :
ionic ‏@Ionicframework 12 hil y a 12 heures
We’ve updated @ionic/app-scripts to fix some issues (like out-of-memory). RC.0 apps should run npm install —save @ionic/app-scripts@latest

Error :

Have you try with sudo too?

 sudo npm install —save @ionic/app-scripts@latest

Yes still getting the error...

[peterpeterparker]

 sudo npm install --save-dev @ionic/app-scripts@latest
