今天要用pod管理三方代碼 突然發(fā)現(xiàn)報了這個問題：

/Library/Ruby/Site/2.0.0/rubygems.rb:270:in `find_spec_for_exe': can't find gem cocoapods (>= 0.a) (Gem::GemNotFoundException)
    from /Library/Ruby/Site/2.0.0/rubygems.rb:298:in `activate_bin_path'
    from /usr/local/bin/pod:22:in `<main>'

然后更新下ruby環(huán)境發(fā)現(xiàn)一直提示：

    Latest version currently installed. Aborting.

一直就不可以，于是上網(wǎng)查了下，說淘寶的Gems源停止更新了。
替換成ruby-china的鏡像。
步驟：

1. 查看現(xiàn)在鏡像源 ：gem source 
2. 刪除淘寶鏡像 ：gem source --remove https://ruby.taobao.org/
3. 添加ruby-china的鏡像源： gem source -a https://gems.ruby-china.org/
4. 安裝pod： gem install cocoapods
5. 輸入密碼 等待安裝成功
6. 初始化pod：pod setup 等待完成就ok了

參考：更換ruby官方源到非taboo源的另一源：ruby-china源方法

2、pod search xxx 時候提示

[!] Unable to find a pod with name, author, summary, or description matching `FMDB`

只需要在終端輸入：

rm ~/Library/Caches/CocoaPods/search_index.json

再次去search 就好了

3、

-bash: /usr/local/bin/pod: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby: bad interpreter: No such file or directory

只需要在終端輸入：

sudo gem install -n /usr/local/bin cocoapods

就ok了
