React version:

  3. yarn start or npm start
  • usually try 2 to 3 times for yarn start, the issue will happen

Link to code example: https://github.com/1846689910/type-18-hek

The current behavior

After run yarn start

events.js:292
      throw er; // Unhandled 'error' event
      ^

Error: read ECONNRESET

@here I think I figured out a solution, which are not 100% guaranteed will solve the issue when npm start every time, but it works most time. It may be issue with inotify watcher limit. Please check https://github.com/guard/listen/wiki/Increasing-the-amount-of-inotify-watchers.

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

if illegal option -- p, maybe try sudo sysctl -e
