FatalErrorException語法錯誤，意外的'：'，期待';'或「{」在PermissionRegistrar.php

Question

當我重新安裝我的XAMPP和運行我laravel項目，我得到這個錯誤 FatalErrorException

語法錯誤，意想不到的「：」，希望「;」或 '{' 在 PermissionRegistrar.php（線33） 我的代碼是

public function __construct(Gate $gate, Repository $cache, Log $logger) 
{ 
    $this->gate = $gate; 
    $this->cache = $cache; 
    $this->logger = $logger; 
} 
public function registerPermissions(): bool 
{ 
    try { 
     $this->getPermissions()->map(function (Permission $permission) { 
    $this->gate->define($permission->name, function ($user) use($permission) 
{ 
       return $user->hasPermissionTo($permission); 
      }); 
     }); 
     return true; 
    } catch (Exception $exception) { 
     if ($this->shouldLogException()) { 
      $this->logger->alert(
"Could not register permissions because {$exceptiongetMessage()}".PHP_EOL. 
       $exception->getTraceAsString() 
      ); 
     } 
     return false; 
    } 
}

Return type declaration support is added to php 7。所以從

public function registerPermissions(): bool 

刪除: bool（因爲你是目前PHP 31年6月5日），以

public function registerPermissions()
