ENOSPC: System limit for number of file watchers reached ( ReactJS error )

[kermit-klein]

Problem

-React error-
ENOSPC: System limit for number of file watchers reached

Background

When trying to run " yarn start " to start React local server, Ubuntu Linux runs into problem
Server does not start

How did you try to solve the problem?

The meaning of this error is that the number of files monitored by the system has reached the limit

Solution:

Modify the number of system monitoring files

Ubuntu

sudo gedit /etc/sysctl.conf

Add a line at the bottom

fs.inotify.max_user_watches=524288

Then save and exit!

sudo sysctl -p

to check it

Then it is solved!
