我正在运行exp buid：ios并收到以下错误：
[15:49:10] Error while gathering & validating credentials
[15:49:10] Reason:Unexpected response, raw:{"responseId":"0914fb13-b4db-488a-801f-9b8cf5ecfa17","resultCode":7460,"resultString":"Maximum number of certificates generated","userString":"You already have a current iOS Distribution certificate or a pending certificate request.","creationTimestamp":"2018-08-28T10:19:10Z","protocolVersion":"QH65B2","userLocale":"en_US","requestUrl":"https://developer.apple.com/services-account/QH65B2/account/ios/certificate/submitCertificateRequest.action","httpCode":200}
我的开发者帐户中只有2个证书，我不知道为什么会收到此错误。我的应用程序已在应用商店中发布，我想为其发布更新。
我在没有帮助的情况下尝试使用-c。
不过，谢谢。
