它需要在Xcode中设置CocoaPod和命令行工具版本:

重置(卸载并安装)cocoa pod:
在终端上执行以下命令以获取最新的稳定版本:

sudo gem install cocoapods

使用关键字--pre获取最新的预发布:

sudo gem install cocoapods --pre

如何设置/重置命令行工具: 如果您已经支付了Apple开发者帐户/ ID,
可以从Apple下载门户下载最新的命令行工具.

这是当前的beta和稳定的Xcode工具和支持命令行工具下载链接.(确保您使用Apple Developer Account上的高级开发者帐户登录以访问这些链接)

Xcode 10

• Xcode 10
  - (命令行工具(Xcode 10) - 用于macOS 10.14)
  - (命令行工具(Xcode 10) - 用于macOS 10.13)

在系统中安装了最新的命令行工具后,从Xcode菜单中进行设置.

(Xcode菜单项)Xcode▶首选项▶位置▶命令行工具▶选择适当的命令行工具

尝试与终端应用程序相同

安装命令行工具(使用终端应用程序):

xcode-select --install

更改活动目录:

sudo xcode-select -switch /Library/Developer/CommandLineTools
