$ gem sources -l *** CURRENT SOURCES *** https://gems.ruby-china.org # 請確保只有 gems.ruby-china.org $ gem install rails

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>'

參考：http://www.jianshu.com/p/700d2cce348c1.$ sudo gem uninstall cocoapods (移除原來的cocoapods) 2.$ sudo gem install -n/usr/local/bin cocoapods (在osx10.11.5中，安裝cocoapods) 3.$ gem sources -l 4. 若是不是https://ruby.taobao.org/就更換爲： $ gem sources --remove https://rubygems.org/ (移除數據源) $ gem sources -a https://ruby.taobao.org/ (更換數據源) $ gem sources -l (查看數據源) 5.$ pod setup (開始安裝)
