Twilio:尝试启动时没有这样的模块'Alarmofire'

我想学斜纹布的诀窍。目标是从我的应用程序发送短信。即时跟踪 this getting started guide

最后一步是在终端运行这个命令:(是的,我已经改变了 SwiftSMS 以我自己的项目名称)

swift build && ./.build/debug/SwiftSMS    

此命令将导致以下结果:

mymac:myproject myname$swift build&和.build/debug/myproject compile SWIFT模块“MyProject”(1个来源) /卷/myproject/myproject/sources/myproject/main.swift:2:8:错误: 没有这样的模块“alamofire”

^错误:终止(1):/applications/xcode.app/contents/developer/toolchains/xcodedefault.xctoolchain/usr/bin/swift-build-tool -f/volumes/myproject/myproject/.build/debug.yaml主输出:

我还没有在xcode中对twilio进行任何配置。据我所知,这应该发送一个消息,而不做任何Xcode?
