title: npm run build failed, What is the problem here?
body: <p>What is the problem here?
  I tried this:
  rm -rf node_modules
  rm package-lock.json
  npm cache clean --force
  npm install</p>
  <pre><code>root@onlinetest:~/mini-kyc-app/client# npm run build
  
  &gt; client@0.1.0 build /root/mini-kyc-app/client
  &gt; react-scripts build
  
  Creating an optimized production build...
  The build failed because the process exited too early. This probably means the system ran out of memory or someone called `kill -9` on the process.
  npm ERR! code ELIFECYCLE
  npm ERR! errno 1

  npm ERR! Exit status 1
  npm ERR! 
  npm ERR! Failed at the client@0.1.0 build script.
  npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
