當你按現(xiàn)有的順序安裝cocoapods的時候
1.移除現(xiàn)有的Ruby
$gem sources --remove https://rubygems.org/
2.使用淘寶鏡像
$gem sources -a https://ruby.taobao.org/
3.驗證當前ruby版本
$gem sources -l
成功后提示：
*** CURRENT SOURCES ***
https://ruby.taobao.org/
4.開始安裝cocoapods
$sudo gem install cocoa pods
這時候會出現(xiàn)提示离例，需要你升級Ruby
使用ruby -v查看你現(xiàn)有的版本
結(jié)果是：ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin15]
使用ruby list known查看ruby所有版本
如果提示command not found 請先安裝rvm
curl -L get.rvm.io | bash -s stable（安裝ram命令）
查看ruby版本后發(fā)現(xiàn)我們的版本確實太低了，這時候終端輸入rvm install 2.2.2
如果出現(xiàn)這種錯誤：
Searching for binary rubies, this might take some time.

不要著急，下面告訴大家怎么做鄙信，本人在這里卡了一天
終端輸入
brew doctor
錯誤提示：
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!
Warning: The following directories are not writable:
/usr/local/share/man
This can happen if you "sudo make install" software that isn't managed
by Homebrew. If a formula tries to write a file to this directory, the
install will fail during the link step.
You should change the ownership and permissions of these directories.
back to your user account.
sudo chown -R $(whoami) /usr/local/share/man
Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
autoconf
libgpg-error
libtool
pig-config
在輸入：
sudo chown -R $(whoami) /usr/local/share/man
然后輸入
brew link autoconf
brew link libgpg-error
brew link libtool
brew link pig-config
最后再次輸入rvm install 2.2.2
這回就應該可以安裝cocoapods了
安裝cocoa pods命令：sudo gem install cocoapods
