Magento 2: Trouble shooting setup:di:compile

Question

I am in the process to upgrade in existing 2.2.1 installation to 2.2.6.

When I am running setup:di:compile it stops abruptly without throwing any error.

Do it log the error somewhere or what is other way to fix it?

Answer 1

try running with verbosity

magento -vvv setup:di:compile

php logs depend on your system configuration

php --info | grep error
