The solution for Ubuntu webpack rebuild issue.

The problem seems to be the inotify max_user_watches :

sudo echo "fs.inotify.max_user_watches=524288" >> /etc/sysctl.conf

sudo sysctl -p /etc/sysctl.conf

Answer 2

This is a bug within the latest @ngtools/webpack package that the angular-cli uses. To fix this you need to manually downgrade the package:

npm uninstall @ngtools/webpack
npm install --save-dev @ngtools/webpack@1.2.4

After a new cli version, you should remove this from your package.json again

Had the same problem with Ubuntu 16.04. Quick fix:

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

Hope this helps someone!
