1.解决办法
先卸载掉homebrew里面的cocoapods：
brew uninstall cocoapods
然后再用gem的方式安装：
sudo gem install cocoapods
如果不报错就可以直接 pod install了
如果报错，看下边：
问题2：输入密码后发现又特么报错 :While executing gem ... (Gem::FilePermissionError)
ERROR:Whileexecuting gem...(Gem::FilePermissionError)You don't have write permissionsforthe/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/gems/2.6.0directory.mayonggang@mayonggang~%
解决问题2：指定的ruby路径不对，应当使用更新版本的ruby
安装rbenv
指定使用rbenv的gem来执行
安装rbenv
$ rbenv install-l
$ rbenv install-l2.6.102.7.63.0.43.1.2jruby-9.3.4.0mruby-3.0.0rbx-5.0truffleruby-22.1.0truffleruby+graalvm-22.1.0
-最新的是3.1.2。但是我下载失败，换成了3.1.1就没事儿了
$ rbenv install3.1.1
指定ruby 版本
$ rbenv global3.1.1$ rbenv rehash
查找gem路径
$ rbenv which gem/Users/用户名/.rbenv/versions/3.1.1/bin/gem
添加相关路径到PATH中
$ export PATH="$HOME/.rbenv/versions/3.1.1/bin:$PATH"
然后再次 ：sudo gem install cocoapods就可以了
$ sudo gem install cocoapodsPassword:Fetching colored2-3.1.2.gemFetching claide-1.1.0.gemFetching CFPropertyList-3.0.5.gemFetching xcodeproj-1.21.0.gemFetching ruby-macho-2.5.1.gemFetching nanaimo-0.3.0.gemFetching atomos-0.1.3.gemFetching nap-1.1.0.gemFetching molinillo-0.8.0.gemFetching gh_inspector-1.1.3.gemFetching fourflusher-2.3.1.gemFetching escape-0.0.4.gemFetching cocoapods-try-1.2.0.gemFetching netrc-0.11.0.gem。。。
然后就可以开心的pod install 了
如果有些常见的SDK找不到，
[!]Unableto find a specificationfor.....或者[!]Unableto find a pod with name,author,summary,or description matching `....`
那可能是需要更新一下pod
$ pod update
运行pod install时，如果在最后报错：
[!]Anerror occurredwhileprocessing the post-install hook of thePodfile.Nosuch fileordirectory-python/Users/myg/Desktop/P_gitee/1.数字北京/Podfile:139:in``'/Users/myg/Desktop/P_gitee/1.数字北京/Podfile:139:in`block(3levels)infrom_ruby'/Users/myg/.rbenv/versions/3.1.1/lib/ruby/gems/3.1.0/gems/cocoapods-core-1.11.3/lib/cocoapods-core/podfile.rb:196:in`post_install!'/Users/myg/.rbenv/versions/3.1.1/lib/ruby/gems/3.1.0/gems/cocoapods-1.11.3/lib/cocoapods/installer.rb:945:in`run_podfile_post_install_hook'
处理方法：
我的提示语是没有python这个文件路径，
我去Podfile中搜索了一下output =python #{root_path}/DS_BeiJing/Third/BaiDuAI/scheme_desc_collector.py #{root_path}`
