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/'

当CocoaPods这样做的时候，它会下载整个specs repo到~/. CocoaPods。这可能需要一段时间，这取决于您的连接。我会试着先用pod设置明确地做它

问题是你没有安装命令行工具，我相信。 尝试在终端运行:

sudo gem update --system

然后从苹果下载命令行工具 只需搜索“命令行工具”并下载适合您的操作系统的版本。 一旦你安装了它，在终端运行:

sudo gem install cocoapods
pod setup

您将不得不删除回购并重新设置它…

pod repo remove master
pod setup

也许这些信息会有帮助:

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

从cocoapods 1.7.2开始，你可以使用cdn而不是github。它燃烧得很快，挂不起来。从cocopods 1.8.0开始，cdn是默认的。

To use the CDN source in your Podfile: If you don't have private specs: source 'https://cdn.cocoapods.org/' If you have private specs: source 'https://github.com/artsy/Specs.git' - source 'https://github.com/CocoaPods/Specs.git' + source 'https://cdn.cocoapods.org/' Doing this will break your Podfile.lock, so you are likely to need to run pod update to see the changes (be careful, this may update your Pods also). If you have a CI setup, it is recommended to cache the new repo dir as it is very small and would save even more time. With 1.7.2 it should be located at ~/.cocoapods/repos/cocoapods- (yes, with a -), but we're looking to improve the naming in an upcoming release.
