环境：macbookpro - M1 Pro版
按照传统的安装cocoapods后执行pod install报错：
...

查了原因是新版M1的macbookpro架构问题，需要卸载cocoapods，然后通过brew install cocoapods来安装cocoapods。
1. 卸载cocoapods
which pod找到pod执行文件/usr/local/bin/pod
sudo rm -rf /usr/local/bin/pod
接下来找cocopod的安装包的地址，执行：
gem list
*** LOCAL GEMS ***
...
cocoapods (1.11.2)
cocoapods-core (1.11.2)
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)
...
找到后，逐一卸载
sudo gem uninstall cocoapods
···
sudo gem uninstall cocoapods-try
清理完毕。
2. 安装cocoapods
执行
brew install cocoapods
结果
3. 执行pod install成功
pod install
