如何解决 pod install 问题并成功运行 pod install？

Question

在干净的 macOS Sonoma 安装并安装 Xcode 15.4 后，我在尝试为客户重新编译和构建项目时遇到了同样的问题。当我运行

pod install

时，遇到以下错误：

它似乎与

rexml

宝石有关。我怎样才能解决这个问题并成功运行

pod install

？

Answer 1

为了解决该问题，我按照以下步骤操作：

1. 卸载的CocoaPods：

   sudo gem uninstall cocoapods
   

2. 已卸载

   rexml

   ：

   sudo gem uninstall rexml
   

3. 已安装CocoaPods版本1.13.0：

   sudo gem install cocoapods -v 1.13.0
   

4. 再次卸载

   rexml

   （为了安全起见）。

5. 已安装

   rexml

   版本3.2.4：

   sudo gem install rexml -v 3.2.4
   

执行这些步骤后，我能够成功运行

pod install

，而不会遇到

TypeError: wrong argument type String (expected Regexp)

错误。

该问题似乎是由最新版本的 CocoaPods 和

rexml

之间的兼容性问题引起的。通过将 CocoaPods 降级到版本 1.13.0 并安装特定版本的

rexml

（3.2.4），冲突得到解决。
