Why doesn't webpack reload a page after changing a file (component)?

Question

webpack

Such a disaster. Under OSX, webpack works fine, reloads after changes are made. But I deployed the project to ubuntu and the changes are applied only after I restart the webpack. And after I restarted him, he reloads the page 1 time and that's it. Doesn't want any more. There are no errors in the console or in the bash. What could be the problem? Who faced?
PS Changes are not applied even after I reload the page myself

Fixed, break a ton of information) If someone encounters the same problem on Linux, then type in:

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