php - PhalconLoaderLoader not found

I have a newly cloned phalcon repository:

software: MacOS
Phalcon: 5.0.0RC4
PHP: 8.1
Zephir: 0.16.0
brew: phalcon@4.1.0
Location: ~/Documents/cphalcon

I am trying to set up my new repository by following the tutorial here.
However when I go to my page at localhost:8000, this error pops up:

Fatal error: Uncaught Error: Class "Phalcon\Loader\Loader" not found in /Users/apple/Documents/cphalcon/public/index.php:16 Stack trace: #0 /Users/apple/Documents/cphalcon/.htrouter.php(15): require_once() #1 {main} thrown in /Users/apple/Documents/cphalcon/public/index.php on line 16

I found some similar thread and they said to check my phpinfo to see if phalcon is there, and it was.
I checked for more materials but couldn't find any other clues.
I also tried changing the call to:

use Phalcon\Loader;

But it was the same

Fatal error: Uncaught Error: Class "Phalcon\Loader" not found in /Users/apple/Documents/cphalcon/public/index.php:16 Stack trace: #0 /Users/apple/Documents/cphalcon/.htrouter.php(15): require_once() #1 {main} thrown in /Users/apple/Documents/cphalcon/public/index.php on line 16

Any clues?

Solution:

I believe that in version 5 the proper syntax now is Phalcon\Autoload\Loader().

Since Phalcon 5 is still in Release Candidate mode (hence the "RC4" on the version), the docs are still lagging a bit behind.

I've converted a couple of Phalcon 3 and 4 sites, and I found the Phalcon 5.0.0RC4 ChangeLog to be helpful when moving from Phalcon 4 to 5. The move from 3 to 5 is far more involved and requires finding the Phalcon 4 update doc on the Phalcon web site.

I hope this helps.
