Wordpress installer upgrades haven’t worked since the change to wp-cli. Running wp-cli 1.4.1. Executing from the command line works great. Installing from the Virtualmin interface works great. However, upgrading gives me the following:
Upgrading WordPress to version 4.9.1 ..
Configuring webserver PHP settings ..
.. already done.

wp core upgrade failed :
.. done
Looking at the system logs, I'm seeing:
sh: core: command not found
It’s supposed to be running “wp core upgrade --version=4.9.1”. But that error message leads me to believe it’s leaving off the “wp” from the command.
Looking in wordpress.pl in the scripts directory, for “!upgrade”, the script sets my $wp and then executes it. However, when upgrading, the script does NOT set my $wp, it simply goes straight to executing it. From troubleshooting, it would seem that $wp is not initialized during an upgrade procedure(the else condition) and is null.
