It seems like $realPath of type string is incompatible with the declared type Ray\Di\Annotation\ScriptDir of property $scriptDir.

The property scriptDir is declared read-only in Ray\Compiler\CompiledInjector.

It seems like $this->scriptDir of type string is incompatible with the declared type Ray\Di\Annotation\ScriptDir of property $scriptDir.

        if (in_array($scriptDir, self::$scriptDirs, true)) {

self::scriptDirs of type Ray\Compiler\ScriptDirs is incompatible with the type array expected by parameter $haystack of in_array().

            return;
        }

        if (self::$scriptDirs === []) {

The condition self::scriptDirs === array() is always false.
