作为本次讨论的结果https://github.com/CocoaPods/CocoaPods/issues/4989

简要: CocoaPods存储库从GitHub获取了大量数据，这就是问题所在。自1.0.0.beta.6版本以来已有更改。

本文档提供的提示:

If for whatever reason you cannot upgrade to version 1.0.0 just yet, you can perform the following steps to convert your clone of the Master spec-repo from a shallow to a full clone:

$ cd ~/.cocoapods/repos/master
$ git fetch --unshallow

我的第一次安装方法:

1. pod setup
2. Ctrl+C
After that I could find ~/.cocoapods/repos/ empty directory 
3. Download  https://github.com/CocoaPods/Specs/archive/master.zip
4. unpack it to ~/.cocoapods/repos/
5. Move to project folder
6. pod install --no-repo-update

而今天则需要将近15分钟

我目前使用的是另一种解决方案。通过更改Podfile中的存储库URL为:

source 'https://cdn.cocoapods.org/'

变化:

- source 'https://github.com/CocoaPods/Specs.git'
+ source 'https://cdn.cocoapods.org/'

上面的解决方案都不适合我，我不得不卸载coacoapods，然后安装一个特定的版本，然后一切才适合我

sudo gem uninstall cocoapods

然后

sudo gem install cocoapods -v 1.7.5

现在，即使是冗长也显示了进步

$ pod setup --verbose

Setting up CocoaPods master repo

Cloning spec repo `master` from `https://github.com/CocoaPods/Specs.git` (branch `master`)
  $ /usr/bin/git clone https://github.com/CocoaPods/Specs.git --progress -- master
  Cloning into 'master'...
  remote: Enumerating objects: 295, done.        
  remote: Counting objects: 100% (295/295), done.        
  remote: Compressing objects: 100% (283/283), done.        
  Receiving objects:  20% (744493/3722462), 132.93 MiB | 567.00 KiB/s   

你可以试着在verbose模式下运行:

pod install --verbose

这将告诉你可可豆荚的作用:

Setting up CocoaPods master repo

Cloning spec repo `master` from `https://github.com/CocoaPods/Specs.git` (branch `master`)
  $ /usr/bin/git clone 'https://github.com/CocoaPods/Specs.git' master
  Cloning into 'master'...

(如此处所示)

对我来说，上面的步骤花了很长时间，因为回购(2016年12月)现在是1.1 GB

您将不得不删除回购并重新设置它…

pod repo remove master
pod setup
