The Metro Bundler is prepared to go. A glitch has occurred: ENOSPC ERROR - the maximum number of file watchers allowed by

The Metro Bundler is now prepared.

An issue has occurred: ERROR ENOSPC - The system limit for the number of file watchers has been reached. Please watch out for this.

Answer №1

Here is the solution I found for fixing this issue:

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

After that, run:

sysctl --system

Answer №2

If you're not keen on diving into the technical details and just want to make Listen work:

If you're using Debian, RedHat, or another Linux distribution of a similar nature, enter this command in your terminal:

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

If you're on ArchLinux, use the following command instead (find out why here):

echo fs.inotify.max_user_watches=524288 | sudo tee /etc/sysctl.d/40-max-user-watches.conf && sudo sysctl --system

Copy and paste this into your terminal, then hit enter to execute.
