由于需要最新版本的Xcode工具，就升级了电脑系统到10.15.4 (19E287)。安装了最新Xcode11.4安装后发现 cocoapods使用出现异常。需要重新安装cocoapods.
安装
因为Mac电脑自带Ruby环境，我们就只需打开终端直接安装就可以了。如果出现ruby版本过低的情况可以先更新ruby。
1.查看当前ruby版本
ruby -v
2.升级ruby环境(升级ruby需要借助rvm,需要先安装rvm)
1.curl -L https://get.rvm.io | bash -s stable
2.source ~/.rvm/scripts/rvm
3.rvm -v
如果要升级rvm使用命令
rvm get stable
3.安装ruby
1.rvm list known
结果为
# MRI Rubies
[ruby-]1.8.6[-p420]
[ruby-]1.8.7[-head] # security released on head
[ruby-]1.9.1[-p431]
[ruby-]1.9.2[-p330]
[ruby-]1.9.3[-p551]
[ruby-]2.0.0[-p648]
[ruby-]2.1[.10]
[ruby-]2.2[.10]
[ruby-]2.3[.8]
[ruby-]2.4[.6]
[ruby-]2.5[.5]
[ruby-]2.6[.3]
[ruby-]2.7[.0-preview1]
ruby-head
此时可以根据自己的需要安装指定版本的ruby。
rvm install 2.6.3
本文相关操作是在ruby[ruby-]2.6[.3]完成的。
4.更换镜像源(如果已经处理可忽略此步骤)
sudo gem update --system
gem sources --remove https://rubygems.org/
gem sources --add https://gems.ruby-china.com/
查看更换结果
gem sources -l
*** CURRENT SOURCES ***
https://gems.ruby-china.com
5.安装cocoapods 10.11后命令 之前的命令为(sudo gem install cocoapods)
sudo gem install -n /usr/local/bin cocoapods
此时如果出现以下错误，原因是因为在安装xcode的时候保留了之前的版本，当前系统上有两个版本的xcode.

处理步骤
5.1 把最近安装的xocde拖到中，注意名称要为xcode默认名。

5.2 终端执行命令
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
5.3 再次执行安装命令
sudo gem install -n /usr/local/bin cocoapods
安装中...

此时等待命令执行完毕就可以了。
完成后搜索测试出现以下错误。

终端执行命令 即可
pod repo remove trunk

此时就可以正常搜索查询检索了。
总结:
1.本文的场景是升级mac系统.
2.安装并保留了多个xcode.
3.pod search xx 命令长时间卡住没有正确返回.
