Is anyone learning ReactJS experiencing an error: “ENOSPC: System limit for number of file watchers reached“? I just experienced it. But don’t worry because there is a solution.
This error occurs when running the “npm start” command. Causes of ENOSPC errors: System limit for number of file watchers reached because the number of files monitored by the system has reached its limit.
The way is to modify the amount in the monitoring system file. Here’s how to modify max_user_watches on Ubuntu. (Ubuntu I use is Ubuntu version 18.04)
1. Open file sysctl.conf (I use VIM to make data modifications)
sudo vim /etc/sysctl.conf
2. Add a line at the bottom
3. Save and Reboot your PC.
4. Check again whether it has been updated with the following command
sudo sysctl -p
Please try the ‘npm start‘ command again.
Thus a brief tutorial on how to Fix React Error: ENOSPC: System limit for number of file watchers reached in ReactJS. Hopefully, useful.
