Git Cocoapods终端错误

我git克隆了一个github项目，然后当我运行pod安装时，它在获取一些文件或其他东西时出错。如何解决这个问题

这是终端代码

Lucs-iMac:twiliochat-swift lucmollard$ pod install
Updating local specs repositories

CocoaPods 1.0.0.beta.6 is available.
To update use: `gem install cocoapods --pre`
[!] This is a test version we'd love you to try.

您需要先删除

twiliochat.xcworkspace

和

Podfile.lock

，然后才能安装

pod

或者您可以只运行

pod update
