ng serve --open
Every time i change I have to restart the server.

use `watch` flag too `ng serve --open --watch` – Aravind Dec 06 '17 at 06:47

Its not working – Vijay V. Dec 06 '17 at 06:50

hot/live reload is by default with angular cli, specifying watch flag explicitly is a bit weird! – Peter Dec 06 '17 at 06:51

which version of cli are you using? – Peter Dec 06 '17 at 06:51

try
ng serve --open --watch
if this does not work try cache clean and npm install
If you are using Ubuntu Try reseting the number of watches this might solve the problem
echo 65536 | sudo tee -a /proc/sys/fs/inotify/max_user_watches

If ubuntu Try increasing watches `sudo sysctl fs.inotify.max_user_watches=524288 sudo sysctl -p --system` – Vignesh Dec 06 '17 at 09:42

As mentioned in a similar answer here, try deleting your node_modules folder and running npm install again. This should upgrade a bad npm dependency.
I would recommend deleting cache as well, follow below steps:
- Delete node_modules folder.
npm cache clean.npm install.
Since you are using a relatively older version of CLI, it would be better to update that as well!

In Ubuntu run this command when your Angular page does not detect changes.
echo 65536 | sudo tee -a /proc/sys/fs/inotify/max_user_watches

This is no different than what is suggested in the 2nd part of Vignesh's existing answer... – Ross Jun 08 '18 at 20:29
