    The `laravel/framework` already has `illuminate/support` included. If you have the framework installed (which you do) you don't need to install `illuminate/support` separately. – jszobody Jul 07 '20 at 13:12
  • Did you try to install the 6.18 version? Illuminate packages requires to be in the same version as laravel, the logs indicates you are trying to install the version 7.x – manuerumx Jul 07 '20 at 13:12

  • @manuerumx..yes i also tried " composer require illuminate/support "v6.18.0"" but giving me same error – Pranav Patel Jul 07 '20 at 13:18

The laravel/framework already has illuminate/support included. If you have the framework installed (which you do) you cannot install another version of illuminate/support separately as it will cause conflicts in PSR-4 namespacing. This is something that can be done in node but not in composer with PHP.
