ios - Carthage 代码符号错误

Question

我克隆了 this iOS application来自 github 并尝试运行 carthage使用文档中概述的 carthage update。但是，当我这样做时，我收到一条错误消息(实际上，这是我的整个终端输出):

Deans-MacBook-Air:SwiftWeather deang$ carthage update
*** Fetching SwiftyJSON
*** Fetching Alamofire
*** Checking out Alamofire at "1.3.1"
*** Checking out SwiftyJSON at "2.2.1"
*** xcodebuild output can be found in /var/folders/p0/chbxzj8920v2gwrqfcnb8p380000gn/T/carthage-xcodebuild.fdWo4D.log

The following build commands failed:
    Check dependencies
(1 failure)
Code Sign error: No code signing identities found: No valid signing identities (i.e. certificate and private key pair) matching the team ID “(null)” were found.
CodeSign error: code signing is required for product type 'Framework' in SDK 'iOS 8.4'
A shell task failed with exit code 65:

Cartfile 看起来像这样:

github "Alamofire/Alamofire"
github "SwiftyJSON/SwiftyJSON" 

现在我不知道这是否是该项目特有的(虽然我不这么认为，它是一个非常受欢迎的项目，似乎没有其他人在提示)。所以我倾向于认为这是我做错了什么或者我的环境有问题。

您无需在 Xcode 7 上付费即可构建/安装应用程序，只需将您的 Apple ID 登录到 Xcode。
