Now the magento version is 2.2.6 target version is 2.3.1 :

http://magefoo.com/upgrade-magento-from-2.2.6-to-2.3.0/
In the 8th step i.e 'composer update' the error happens :
Current PHP version is 7.0.3 while using this version no error but composer hangs at updating dependencies
I updated the PHP version to 7.1.9 then at composer update step the error happens is :
