HP Fatal error: Uncaught Error: Undefined constant "Hitrov\CURLOPT_URL"

[MissionTrouble]

While trying to use this script, I got an error "PHP Fatal error: Uncaught Error: Undefined constant "Hitrov\CURLOPT_URL" in /home//.oci/oci-arm-host-capacity/src/OciApi.php:243
Stack trace:
#0 /home//.oci/oci-arm-host-capacity/src/OciApi.php(132): Hitrov\OciApi->call()
#1 /home//.oci/oci-arm-host-capacity/index.php(74): Hitrov\OciApi->getInstances()
#2 {main}
thrown in /home//.oci/oci-arm-host-capacity/src/OciApi.php on line 243"
After googling the error it seemed to be an issue with not having curl installed, but after running curl --version
I got this response

Im not sure where to go from here.
