10.12-cocoapods

1、检查当前ruby版本

$gem sources -

成功后提示：

*** CURRENT SOURCES ***

https://ruby.taobao.org/

否则，移除现有的ruby：$gem sources --remove https://rubygems.org/；添加使用淘宝镜像：$gem sources -a https://ruby.taobao.org/

2、开始安装cocoapods

$sudo gem install cocoapods

运行后出现错误

2.1检查ruby版本

$ruby -v

ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin15]

2.2需要升级ruby；

查看目前所有ruby版本：$rvm list known 如果提示command not found

$curl -L get.rvm.io | bash -s stable

请先安装rvm：rvm install 2.2.2 ；如果不成功，检查homebrew卸载安装

卸载：

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

Failed to locate Homebrew!

解决问题：删除原来的安装目录

rm -rf Cellar Frameworks Homebrew

重新执行安装：

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

运行后有下边提醒，则出现安装成功：

==> Installation successful!

在执行：$ rvm install 2.2.2

运行结果：

Please be aware that you just installed a ruby that requires        1 patches just to be compiled on an up to date Linux system.

This may have known and unaccounted for security vulnerabilities.

Please consider upgrading to ruby-2.3.0 which will have all of the latest security patches.

Ruby was built without documentation, to build it run: rvm docs generate-ri成功

之后就开始安装cocoapods：$sudo gem install cocoapods

结果：

Installing ri documentation for cocoapods-1.0.1

Done installing documentation for nap, fourflusher, escape, colored, concurrent-ruby, thread_safe, tzinfo, i18n, activesupport, claide, xcodeproj, molinillo, cocoapods-try, netrc, cocoapods-trunk, cocoapods-stats, cocoapods-search, cocoapods-plugins, cocoapods-downloader, cocoapods-deintegrate, fuzzy_match, cocoapods-core, cocoapods after 146 seconds

23 gems installed

则安装成功 》

谨记：运行pod install时总是卡在Setting up CocoaPods master repo，因为这条命令被墙了，换成pod install --verbose --no-repo-update

pod update --- > pod update --verbose --no-repo-update
