所以我之前在 Google AdWords API 中使用ClientLogin进行授权，但是在查看AuthForInstalledApps之后，它说这种机制已被弃用，取而代之的是OAuth2.0
我已经在API Consoles中注册了我的应用程序。现在我正在尝试按照 perl 示例进行设置：
我无法将 AdWords 客户端、凭据放在 ~/adwords.properties中，因为我有多个帐户，我将对其进行广告系列管理操作，因此有多个客户端 ID。
但是现在我试图通过只使用我的一个客户的信息来遵循这个例子，如下所示：
my $client = Google::Ads::AdWords::Client->new(
{
version => 'v201206',
developer_token => TOKEN,
client_id => $google_account_id
}
);
$client->get_auth_token_handler()->set_email($login);
$client->get_auth_token_handler()->set_password($password);
但是，当我逐步执行此操作时，当它尝试初始化Client对象时会引发此错误：

我正在使用Perl v5.8.8. 我已经安装了最新的Adwords Perl Client Library v2.7.2. 是否存在某种依赖问题？我该如何解决这个问题。您可以提供的任何信息都会非常有帮助。谢谢。
