安裝流程：
- 確認(rèn)
ruby是否安裝
$ruby -v
ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin15]
- 更換
gem源:http://rubygems-china.oss.aliyuncs.com
$gem sources -l
*** CURRENT SOURCES ***
https://rubygems.org/
$gem sources --remove https://rubygems.org/
https://rubygems.org/ removed from sources
$gem sources -a http://rubygems-china.oss.aliyuncs.com
- 安裝
cocoapods
$sudo gem install cocoapods
...gems installed
下面這步很容易出錯(cuò)
pod setup
或者
pod search FMDB
Creating search index for spec repo 'master'.. Done!
