Pod 安装错误后，Swift 3 结果出现编译错误

从 Swift 2.3 迁移到 Swift 3 后，出现以下编译错误：

第一：

错误：无法从“目标支持文件/Alamofire-watchOS/Alamofire-watchOS.modulemap”读取模块映射内容：错误域=NSCocoaErrorDomain Code=260 “无法打开文件“Alamofire-watchOS.modulemap”因为没有这样的文件。”

第二：

错误：无法从“目标支持文件/SwiftyJSON-watchOS/SwiftyJSON-watchOS.modulemap”读取模块映射内容：错误域=NSCocoaErrorDomain Code=260“文件“SwiftyJSON-watchOS.modulemap”无法打开因为没有这样的文件。”
