正在运行 pod 安装...
CocoaPods 的输出:
↳
CDN:trunk 相对路径:CocoaPods-version.yml 存在!返回本地，因为检查仅在 repo 更新中执行
CocoaPods 的错误输出:

这似乎是 Cocoapods v 1.11.0 中的一种错误/不兼容问题
为了解决这个问题，我按照以下步骤操作，它就像一个魅力:https://stackoverflow.com/a/69076515/16881741
简而言之，请按照以下步骤操作:

在您的终端中，在 ios 文件夹类型中gem list --local | grep cocoapods

记下上一个命令的输出是什么。看起来像这样(请忽略各个条目附近的版本，这是我的输出，我已经使用了 1.10.1 版本):

cocoapods (1.10.1)
cocoapods-core (1.10.1)
cocoapods-deintegrate (1.0.5)
cocoapods-downloader (1.5.1)
cocoapods-plugins (1.0.0)
cocoapods-search (1.0.1)
cocoapods-trunk (1.6.0)
cocoapods-try (1.2.0)


一一启动命令sudo gem uninstall X用 cocoapods 组件的名称替换“X”，不包含版本。
最后你应该得到这个:

sudo gem uninstall cocoapods
sudo gem uninstall cocoapods-core
sudo gem uninstall cocoapods-deintegrate
sudo gem uninstall cocoapods-downloader
sudo gem uninstall cocoapods-plugins
sudo gem uninstall cocoapods-search
sudo gem uninstall cocoapods-trunk
sudo gem uninstall cocoapods-try确保已包含第 n.1 点中列出的所有组件以避免脏状态

使用命令sudo gem install cocoapods -v 1.10.1获取正确的版本。
