史上最全CocoaPods安装和使用教程
一.正常安装过程
1.先检查ruby的版本
ruby -v
builderdeMac-mini:~ builder$ ruby -v
ruby 2.0.0p481 (2014-05-08 revision 45883) [universal.x86_64-darwin14]
builderdeMac-mini:~ builder$ 截图如下：
2.替换为taobao源（后面发现不行，又换了其他的源，可在后面查看）
gem sources --remove https://rubygems.org/ 移除
gem sources --a https://ruby.taobao.org/ 添加
gem sources - l 查看
builderdeMac-mini:~ builder$ gem sources --remove http://rubygems.org/
source http://rubygems.org/ not present in cache
builderdeMac-mini:~ builder$ gem sources --remove https://rubygems.org/
https://rubygems.org/ removed from sources
builderdeMac-mini:~ builder$ gem sources -a https://ruby.taobao.org/
https://ruby.taobao.org/ added to sources
builderdeMac-mini:~ builder$ gem sources -l
*** CURRENT SOURCES ***
https://ruby.taobao.org/
3.安装cocoapods
sudo gem install cocoapods
builderdeMac-mini:~ builder$ sudo gem install cocoapods

出现上面的log说明安装成功了，否则出问题了。
---------------------------------------------------------------------------------------------------------------------
二.安装过程出现问题解决
1.安装cocoapods遇到ruby版本过低问题：
builderdeMac-mini:~ builder$ sudo gem install cocoapods

builderdeMac-mini:~ builder$ 
解决方案：
1）.先安装rvm版本管理
curl -L get.rvm.io | bash -s stable
builderdeMac-mini:~ builder$ curl -L get.rvm.io | bash -s stable

Installing RVM to /Users/builder/.rvm/
Adding rvm PATH line to /Users/builder/.profile /Users/builder/.mkshrc /Users/builder/.bashrc /Users/builder/.zshrc.
Adding rvm loading line to /Users/builder/.profile /Users/builder/.bash_profile /Users/builder/.zlogin.
Installation of RVM in /Users/builder/.rvm/ is almost complete:
* To start using RVM you need to run `source /Users/builder/.rvm/scripts/rvm`
in all your open shell windows, in rare cases you need to reopen all shell windows.
# builder,
#
# Thank you for using RVM!
# We sincerely hope that RVM helps to make your life easier and more enjoyable!!!

------------------------------------------------------------------------------
RubyGems installed the following executables:
/Users/builder/.rvm/rubies/ruby-2.2.2/bin/gem
Ruby Interactive (ri) documentation was installed. ri is kind of like man
pages for ruby libraries. You may access it like this:
ri Classname
ri Classname.class_method
ri Classname#instance_method
If you do not wish to install this documentation in the future, use the
--no-document flag, or set it as the default in your ~/.gemrc file. See
'gem help env' for details.
RubyGems system software updated
builderdeMac-mini:~ builder$
builderdeMac-mini:~ builder$ gem升级完成了。
---------------------------------------------------------------------------------------------------------------------
三.使用cocospods前准备
cocoapods安装成功后，先pod setup
pod setup卡着不动问题
builderdeMac-mini:~ builder$ pod setup
Setting up CocoaPods master repo淘宝的源不可用，用其他的，或者 新开一个终端窗口，输入"cd ~/.cocoapods/"命令行跳到cocoapods文件夹内，执行"du -sh *"查看正在下载的文件夹的大小，如果没有大小变化，说明这个源有问题，需替换。
builderdeMac-mini:~ builder$ gem sources -l
*** CURRENT SOURCES ***
https://ruby.taobao.org/
builderdeMac-mini:~ builder$ gem sources -r https://ruby.taobao.org/
https://ruby.taobao.org/ removed from sources
builderdeMac-mini:~ builder$ gem sources -a https://gems.ruby-china.org/
https://gems.ruby-china.org/ added to sources
builderdeMac-mini:~ builder$ gem sources -l
*** CURRENT SOURCES ***
https://gems.ruby-china.org/
builderdeMac-mini:~ builder$ 1）、那是因为 淘宝的那个镜像(https://ruby.taobao.org/ )已经不可用了。所以我们现在用最新支持的ruby镜像(https://gems.ruby-china.org/)
需要的命令行：
$ gem sources -r https://rubygems.org/ （移除旧版本的镜像，如果你不知道你电脑上目前用的是什么镜像，可用 $ gem sources -l 来查看）
$ gem sources -a https://gems.ruby-china.org/ （增加可用的镜像）
$ gem sources -l （用来检查使用替换镜像位置成功）
2）、当pod setup 进入Setting up CocoaPods master repo 等待的时候表示正在下载了，此时你可通过新开一个终端窗口，输入"cd ~/.cocoapods/"命令行跳到cocoapods文件夹内，执行"du -sh *"查看正在下载的文件夹的大小
builderdeMac-mini:~ builder$ cd ~/.cocoapods/
builderdeMac-mini:.cocoapods builder$ du -sh
3.7M .
builderdeMac-mini:.cocoapods builder$ du -sh
4.3M .
builderdeMac-mini:.cocoapods builder$ du -sh
4.5M .
builderdeMac-mini:.cocoapods builder$ du -sh
4.8M .
builderdeMac-mini:.cocoapods builder$ du -sh
8.6M .
builderdeMac-mini:.cocoapods builder$ 3）、当出现如下
[!] An error occurred while performing `git pull` on repo `master`.
[!] /usr/bin/git pull --ff-only
这个错误应该是说这个节点有问题。就又找资料，然后试试把cocoapods的节点删除，重新添加一个节点，或许就行，说干就干：
原因： Cocoapods的分支不支持当前最新的Xcode版本
解决办法: 删除master分支 重新建立新的分支
sudo rm -fr ~/.cocoapods/repos/master
然后再: pod setup
正确过程如下：
builderdeMac-mini:~ builder$ pod setup
Setting up CocoaPods master repo
CocoaPods 1.1.0.rc.2 is available.
To update use: `sudo gem install cocoapods --pre`
[!] This is a test version we'd love you to try.
For more information, see https://blog.cocoapods.org and the CHANGELOG for this version at https://github.com/CocoaPods/CocoaPods/releases/tag/1.1.0.rc.2
Setup completed
builderdeMac-mini:~ builder$
---------------------------------------------------------------------------
四.cocoapods使用过程
cd进入到项目目录
builderdeMac-mini:PodTest builder$ ls
PodTest PodTest.xcodeproj
builderdeMac-mini:PodTest builder$ vi Podfileplatform :ios, '7.0'
#use_frameworks!个别需要用到它，比如reactiveCocoa
target 'PodTest' do
pod 'AFNetworking', '~> 2.6'
pod 'MBProgressHUD', '~> 1.0.0'
end如图：
这时候你会发现项目底下有了一个名叫Podfile的文稿
然后pod install
builderdeMac-mini:PodTest builder$ pod install
Analyzing dependencies
Downloading dependencies
Installing AFNetworking (2.6.3)
Installing MBProgressHUD (1.0.0)
Generating Pods project
Integrating client project
[!] Please close any current Xcode sessions and use `PodTest.xcworkspace` for this project from now on.
Sending stats
Pod installation complete! There are 2 dependencies from the Podfile and 2 total pods
installed.
builderdeMac-mini:PodTest builder$ PodTest.xcworkspace
Pods
如图：
这时候的项目入口变成了.xcworkspace文件，而不是.xcodeproj
打开项目使用刚配置的库，运行成功，至此cocoapods使用过程已完成。
截图如下：
