pod update

正如这里指出的，git-remote-http进程在后台运行。我从活动监视器到这个过程，退出这个过程恢复了pod进程，在pod安装后卡住了“更新本地规格存储库”

我也遇到了同样的问题，我通过运行下面给出的命令来解决它

pod repo remove master
pod setup
pod install

找到了另一种下载cocoapods的方法，就是下载这里提供的快照之一。它有点旧，但是.bz2压缩文件下载起来要快得多。一旦我下载了它，我将它复制到~/。cocoapods/repos/然后我使用bzip2 -dk *.bz2解压缩它。

解压缩需要一段时间，完成后，我将新解压缩文件的扩展名更改为.tar，并执行tar xvf *.tar来解压缩。这将显示正在创建的文件列表，也需要一段时间。

Finally when I ran pod repo list while inside the project folder, it showed the master folder had been added as a repo. Because I still kept getting an error that it was unable to find the specification for the pod I was looking for, I went to the master folder and did git fetch and then git merge. The git fetch took the longest, about an hour at 50 KB/s. I used fetch and merge instead of pull, as I was having issues with it, i.e. fatal: the remote end hung up unexpectedly. It is now up to date and I was able to get the pod I wanted.

我是这样解决这个问题的:

rm -fr ~/Library/Caches/CocoaPods && \
gem update --system && \
gem update && \
gem cleanup && \
pod setup
