PHP fatal error installing zulu on pbxact

I’m new on freepbx. Working on upgrading a pbxact to zulu 3. Had a real headache getting pm2 installed but thats done. However, when I try to install zule from command line per wiki, I get this.

Look in the same thread about this

Thanks for the prompt response, installing now.
