I keep getting this error:

joaopedro@joaopedro-HP-EliteDesk-800-G1-DM:~/oci/oci-arm-host-capacity$ ls
composer.json composer.lock images index.php LICENSE README.md src tests

joaopedro@joaopedro-HP-EliteDesk-800-G1-DM:~/oci/oci-arm-host-capacity$ php index.php
PHP Warning: require(vendor/autoload.php): Failed to open stream: No such file or directory in /home/joaopedro/oci/oci-arm-host-capacity/index.php on line 8

I tried with sudo but get the same error. This autoload.php is nowhere to be found
