Node.JS: Getting error : [nodemon] Internal watch failed: watch ENOSPC

It appears that my max ports weren't configured correctly. I ran the following code and it worked...

echo fs.inotify.max_user_watches=582222 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

What this command does is to increase the number of watches allowed for a single user. By the default the number can be low (8192 for example). When nodemon tries to watch large numbers of directories for changes it has to create several watches, which can surpass that limit.

You could also solve this problem by:

sudo sysctl fs.inotify.max_user_watches=582222 && sudo sysctl -p

But the way it was written first will make this change permanent.

On running node server shows Following Errors and solutions:

nodemon server.js

[nodemon] 1.17.2

[nodemon] to restart at any time, enter rs

[nodemon] watching: .

[nodemon] starting node server.js

[nodemon] Internal watch failed: watch /home/aurum304/jin ENOSPC

sudo pkill -f node

or

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

Erik, You can just kill all the other node processes by

pkill -f node

and then restart your server again. It'll work just fine then.
