我最近重新格式化了Macbook，丢失了所有项目，幸运的是，我将它们全部保存在GitHub页面上，所以我又重新下载了它们
问题是当我尝试使用“ pod install”安装Pod时，Cocoapods返回了如下错误：
/Library/Ruby/Gems/2.3.0/gems/cocoapods-1.7.0/lib/cocoapods/command.rb:118:in `git_version': Failed to extract git version from `git --version` ("") (RuntimeError)
from /Library/Ruby/Gems/2.3.0/gems/cocoapods-1.7.0/lib/cocoapods/command.rb:130:in `verify_minimum_git_version!'
from /Library/Ruby/Gems/2.3.0/gems/cocoapods-1.7.0/lib/cocoapods/command.rb:49:in `run'
from /Library/Ruby/Gems/2.3.0/gems/cocoapods-1.7.0/bin/pod:55:in `<top (required)>'
from /usr/local/bin/pod:22:in `load'
from /usr/local/bin/pod:22:in `<main>'
我已经删除了Git和Cocoapods并重新安装了它们，我从Xcode /位置中的下拉菜单中选择了Git版本，并且没有任何改变
