Php MAMP本地开发-cURL错误60:SSL证书：无法获取本地颁发者证书

我使用MAMP作为本地开发环境。我想实现一个GoogleAuth，但是不断地得到这个SSL错误

正如其他SO主题所建议的，我已经在PHP.ini文件中添加了这行代码：

并从这里添加了最新的CA证书：在我的PHP SSL文件夹中：C:\MAMP\bin\PHP\php7.4.1\extras\SSL

您知道如何在本地环境中传递此SSL错误吗？

代码如下：

$google_client = new \Google_Client();
    $google_client->setClientId($clientID);
    $google_client->setClientSecret($clientSecret);
    $google_client->setRedirectUri($redirectUri);
    $google_client->addScope("email");
  $google_client->addScope("profile");



    if($this->request->getVar('code')){
        $token = $google_client->fetchAccessTokenWithAuthCode($this->request->getVar('code'));
        if(!isset($token['error'])){
            $google_client->setAccessToken($token['access_token']);
            $this->session->set('access_token', $token['access_token']);

            //get Google profile data
            $google_service = new \Google_Service_Oatuth2($google_client);
            $data = $google_service->userinfo->get();
            print_r($data);

$google_client = new \Google_Client();
    $google_client->setClientId($clientID);
    $google_client->setClientSecret($clientSecret);
    $google_client->setRedirectUri($redirectUri);
    $google_client->addScope("email");
  $google_client->addScope("profile");



    if($this->request->getVar('code')){
        $token = $google_client->fetchAccessTokenWithAuthCode($this->request->getVar('code'));
        if(!isset($token['error'])){
            $google_client->setAccessToken($token['access_token']);
            $this->session->set('access_token', $token['access_token']);

            //get Google profile data
            $google_service = new \Google_Service_Oatuth2($google_client);
            $data = $google_service->userinfo->get();
            print_r($data);
