## `npm start` fail due to watch error

If you are using a Linux operating system and see an error similar to: `ENOSPC: System limit for number of file watchers reached`, you can fix the issue by increasing the `fs.inotify.max_user_watches` setting of your operating system.

If you are running Debian, RedHat, or another similar Linux distribution, run the following in a terminal:

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

If you are running ArchLinux, run the following command instead:

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

Then paste it in your terminal and press on enter to run it. You could find more information [here](https://github.com/guard/listen/wiki/Increasing-the-amount-of-inotify-watchers#the-technical-details).

## `npm test` hangs or crashes on macOS Sierra

If you run `npm test` and the console gets stuck after printing `react-scripts test` to the console there might be a problem with your [Watchman](https://facebook.github.io/watchman/) installation as described in [facebook/create-react-app#713](https://github.com/facebook/create-react-app/issues/713).
