• 1.解決辦法

先卸載掉homebrew里面的cocoapods：
brew uninstall cocoapods

然后再用gem的方式安裝：
sudo gem install cocoapods

如果不報(bào)錯(cuò)就可以直接 pod install了

如果報(bào)錯(cuò)撮胧，看下邊：

• 問(wèn)題2：輸入密碼后發(fā)現(xiàn)又特么報(bào)錯(cuò) :While executing gem ... (Gem::FilePermissionError)

ERROR:  While executing gem ... (Gem::FilePermissionError)

• 解決問(wèn)題2：指定的ruby路徑不對(duì)里烦，應(yīng)當(dāng)使用更新版本的ruby
  安裝rbenv
  指定使用rbenv的gem來(lái)執(zhí)行

• • 安裝rbenv

$ rbenv install -l

$ rbenv install -l
2.6.10
2.7.6
3.0.4
3.1.2
jruby-9.3.4.0
mruby-3.0.0
rbx-5.0
truffleruby-22.1.0
truffleruby+graalvm-22.1.0

• -最新的是3.1.2。但是我下載失敗个初，換成了3.1.1就沒(méi)事兒了

$ rbenv install 3.1.1

• • 指定ruby 版本

$ rbenv global 3.1.1
$ rbenv rehash

• • 查找gem路徑

$ rbenv which gem
/Users/用戶名/.rbenv/versions/3.1.1/bin/gem

• • 添加相關(guān)路徑到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 cocoapods

。歧譬。宜猜。

然后就可以開(kāi)心的pod install 了

如果有些常見(jiàn)的SDK找不到，

[!] Unable to find a specification for .....
或者
[!] Unable to find a pod with name, author, summary, or description matching `....`

那可能是需要更新一下pod

$ pod update

運(yùn)行pod install時(shí)们镜，如果在最后報(bào)錯(cuò)：

[!] An error occurred while processing the post-install hook of the Podfile.

No such file or directory - python

• • 處理方法：
    我的提示語(yǔ)是沒(méi)有python這個(gè)文件路徑币叹，
    我去Podfile中搜索了一下output =python #{root_path}/DS_BeiJing/Third/BaiDuAI/scheme_desc_collector.py #{root_path}`
