我昨天使用phonegap将应用程序安装到iPad上，只需使用：
phonegap run ios
从项目目录中。我今天尝试将它安装到第二台iPad，但该命令什么也没做。然后我打字：
phonegap run ios --device --verbose
得到了：
Code Sign error: No code signing identities found: No valid signing identities (i.e. certificate and private key pair) matching the team ID “***” were found.
CodeSign error: code signing is required for product type 'Application' in SDK 'iOS 8.4'

除了插入设备外，我没有得到与昨天有什么不同？
