1、homebrew安裝（也可自行前往Homebrew）

終端執(zhí)行這句指令：

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

2、RVM安裝（即：Ruby Version Manager）

終端執(zhí)行這句指令：

brew install ruby

等待幾分鐘升級ruby從2.6.1到3.2.+，這個時候 你輸入ruby -v 其實還是2.6.1 那是因為環(huán)境變量沒有指向最新的ruby庫

終端會提示你如果想使用最新的ruby，可以設置環(huán)境變量 export PATH="/usr/local/opt/ruby/bin:$PATH"

其實ruby升級完成后 gem也會升級完成 因為ruby中是有g(shù)em的 ，目前ruby升級到3.2.2的話gem install cocoapod就會報錯是因為cocoapod 不支持這么高的ruby

CocoaPods當前支持的Ruby版本應該是2.5或更高版本。然而，根據(jù)你的錯誤信息，系統(tǒng)中安裝的Ruby版本為3.2.0，這可能是不兼容的版本。所以我們需要降級ruby到2.7。

第一步我們查找下可用的ruby：

brew search ruby

第二步安裝指定的ruby

brew install ruby@2.7

第三步配置終端環(huán)境變量（使終端可以使用指定的ruby，在/Users/b3build/.zshrc，將.zshrc直接點開，然后插入第二行）

export PATH="/usr/local/opt/ruby@2.7/bin:$PATH"

3、ruby鏡像源

先查看ruby鏡像源

gem sources-l

替換ruby鏡像源

gem sources--addhttps://gems.ruby-china.com/--removehttps://rubygems.org/

4、gem升級

因為降級ruby到2.7后，gem就和ruby的版本對上了，但是gem里面一些庫需要升級，也就代表著gem需要升級到新的版本，這個是我們升級ruby到2.7.10后，調(diào)用gem install cocoapods后報的錯，如下提示：需要gem升級到3.4.17

終端執(zhí)行g(shù)em升級到3.4.17：

gem update --system 3.4.17

升級完后查看gem版本是否升級到3.4.17

gem -v

5、cocoapods安裝

gem install cocoapods -V

經(jīng)過幾分鐘的等待，調(diào)用pod 不在報錯說明pod安裝成功了
