npm start not working in react project

Question

I am currently working on a react project and have already developed the basic components. Everything was working fine yesterday. Then I started a new react native project. After installing the project using create-react-native-app, the npm start command failed to start the server but it was working just fine for the react project.

I was using node 10.6 and npm 5.6. After reading some suggestions, I changed node to v8.11 and npm to 6.2. After installing watchman and changing the inotify watches, I finally fot the native app to start.

Today, I tried to start the react project and the server is not starting. This is what the terminal is displaying...

  Starting the development server...

events.js:183
      throw er; // Unhandled 'error' event
      ^

I am using ubuntu 18.04 node 8.11 npm 6.2

Any idea what the problem could be?

Hi, probably duplicate of [this](https://stackoverflow.com/questions/22475849/node-js-error-enospc/32600959#32600959) or look at [this](https://github.com/facebook/create-react-app/issues/2549) — Dominion, Jul 18 '18 at 05:39

You can run the below command to avoid ENOSPC:

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

For Arch Linux add this line to /etc/sysctl.d/99-sysctl.conf:

fs.inotify.max_user_watches=524288

Finally, run:

sysctl --system

This will also persist across reboots.

Can you explain why this solves the original question? All you are doing here is creating a new project and starting it. – Simply Ged May 15 '19 at 00:56
