0x01 解决方案

在stackoverflow中某一回答说, 卸载Brew安装的CoCoaPods, 使用官方命令安装: sudo gem install cocoapods -V.
在使用命令时, 请设置gem的源到国内, 参考: 解决安装不动:

gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/

在安装的过程中可能会提示缺少某某环境, 按照提示安装即可, 本文所安装的环境有:

sudo gem install drb -v 2.0.6 -V
sudo gem install activesupport -v 6.1.7.8 -V
