cocoapods：update失败且不生成workspace

环境： macOS10.12 、Xcode 8.1、cocoapod1.1.1 、ruby 2.2.5

电脑抹盘重装后装cocoapod后出现 [n] xxx abort问题，且没生成workspace文件。

➜  XcodePodTest pod update
Update all pods
Updating local specs repositories

Installing AFNetworking (3.1.0)
Generating Pods project
[1]    54680 abort      pod update

解决方法：

➜  sudo gem install cocoapods --pre

➜  XcodePodTest pod --version

1.2.0.beta.1

更新到1.2.0.beta.1没有上述问题了。

如果更新不成功。尝试重装下cocoapods

#删除 cocoapods gems:

sudo gem uninstall cocoapods
sudo gem uninstall cocoapods-core
sudo gem uninstall cocoapods-deintegrate
sudo gem uninstall cocoapods-downloader
sudo gem uninstall cocoapods-plugins
sudo gem uninstall cocoapods-search
sudo gem uninstall cocoapods-stats
sudo gem uninstall cocoapods-try
sudo gem uninstall cocoapods-trunk

➜ sudo rm -fr ~/Library/Caches/CocoaPods/
➜ sudo rm -fr ~/.cocoapods/repos/master/

➜  ~ gem sources -l
*** CURRENT SOURCES ***

➜  ~ gem sources -l
*** CURRENT SOURCES ***

http://rubygems-china.oss.aliyuncs.com
➜  ~ gem sources --add https://gems.ruby-china.org/ --remove http://rubygems-china.oss.aliyuncs.com
https://gems.ruby-china.org/ added to sources
http://rubygems-china.oss.aliyuncs.com removed from sources

#安装最新 pre release版本 
sudo gem install cocoapods --pre

➜  ~ pod setup
Setting up CocoaPods master repo

# pod setup一般会用较长时间。 查看目标目文件夹大小
➜  ~ cd .cocoapods
➜  .cocoapods du -sh *
920M    repos

再次尝试pod update
