Wild guess - you either using a wrong version of composer OR composer is using a wrong version of PHP.
You might want to just copy/paste the latest M2.3.

Thanks for reply,
In my client server, PHP version is 7.2.16, Composer Version is 1.8 and Magento version is 2.2.6.
Configuration of client server satisfy all requirements of Magento 2.3
And my client wants to upgrade current site version to latest, So i am try to upgrade version to 2.3.0 from 2.2.6 as per mention into magento documents.
Above mention error occurred after run composer update command.
Please let me know if you have another solution.
