  • are u having good net connection? wats ur node and npm version? Commented May 10, 2020 at 18:36
  • It looks like the download of eslint took too long so the install script timed out. Have you tried installing a second time? Commented May 10, 2020 at 18:36
  • my node version is v12.16.3 and npm version is 6.14.4. And I also have a good net connection. I tried to install 4 or 5 times, same case! Commented May 10, 2020 at 18:39
  • Check if there is a firewall or VPN blocking the connection. Commented May 10, 2020 at 18:40
  • To debug try custom installing any package from NPM Repository to know if there is any problem connecting that domain. Commented May 10, 2020 at 18:42

It looks like your internet connection might be slow. Try increasing the timeout in your .npmrc

i don't think so. my net connection is good. what did u say about .npmrc? I didn't understand
If you are on Windows, find the .npmrc file in C:\Program Files\nodejs\node_modules\npm change timeout=50000 Try create-react-app
i have found .npmrc file. But i can't open it. How do i solve this?
Open with Notepad? @AhnaafAlRafee

share the error log, lets see if we find some detail in that to debug.
ps: you did try your npm install after this cache clean command. right?
