看到第一句是不是很有喜感，解决方案：
You need reinstall cocoapods: so
sudo gem uninstall cocoapods
sudo gem install cocoapods
pod setup
坑二：
Invalid `Podfile` file: [!] Unsupported options `{:exclusive=>true}`
for target 'CocoaPodsDemo'
这种一般是pod install别人的工程，解决办法是将：
target 'mySuperApp_Tests', :exclusive => truedo
pod 'mySuperApp', :path => '../'end
改成：
target 'mySuperApp_Tests'do pod 'mySuperApp', :path => '../' end
坑三：
[!] Unable to add a source with url
`https://github.com/CocoaPods/Specs.git` named `master`.
解决办法：
cd ~/.cocoapods/repos
git clone https://github.com/CocoaPods/Specs.git master
还有一种报错是：
[!] Unable to add a source with url `https://github.com/CocoaPods/Specs.git` named `master-1`.
You can try adding it manually in `~/.cocoapods/repos` or via `pod repo add`.
坑七：
sudo gem sources -a https://ruby.taobao.org/
Error fetching https://ruby.taobao.org/:
server did not return a valid file (http://ruby.taobao.org/specs.4.8.gz)
这真的是无妄之灾啊，网上找了半天解决办法，试过https改http，也试过：
1. rvm pkg install openssl
2. rvm reinstall all --force
和
$ gem sources --remove https://rubygems.org/
$ gem sources -a https://ruby.taobao.org/
$ gem sources -l*** CURRENT SOURCES ***
