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

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

我使用了以下4个命令

cd ~/.cocoapods/repos
git clone "https://github.com/CocoaPods/Specs" master --depth 1
cd master
git fetch --unshallow
pod setup

我花了预期的时间，但至少我不必站在屏幕前思考后台发生了什么。

我正在使用监控下载进度

while true; 
do   
du -sh ~/.cocoapods/;   
sleep 3; 
done

进展非常缓慢……失败了几次。 但是在使用命令行git config——global http增加了git缓冲区限制之后。下载速度大大提高，在./cocoapods文件夹上下载了总共347 Mb后，进度似乎停止了，网络活动也停止了。 但在等待几分钟后，发现cocoapod正在验证和提取回购，使总大小达到853 Mb。

注:2016年10月23日。

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/'

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.
