A.打開終端
$ ruby -v #查看ruby的版本
打印代碼：
ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin15]
B. 更換ruby鏡像:
終端輸入如下命令（把Ruby鏡像指向taobao，避免被墻，你懂得）
a.移除現(xiàn)有 Ruby 默認(rèn)源輸入以下指令
$gem sources --remove https://rubygems.org/
C.使用新的源輸入以下指令 :
$gem sources -a https://ruby.taobao.org/
#淘寶源已經(jīng)停更了目前最新的是
$gem source -a https://gems.ruby-china.org
這里附上官網(wǎng)地址 --> RubyGems 鏡像- Ruby China
D.驗(yàn)證新源是否替換成功輸入以下指令:
$gem sources -l #檢查源鏡像的
E.安裝cocoapods
$sudo gem install cocoa pods
這就遇到我的第一個(gè)問題：
如果你的ruby 版本過低 就會(huì)報(bào)錯(cuò)：
ERROR: Error installing cocoa:
activesupport requires Ruby version >= 2.2.2.
ERROR: Error installing pods:
activesupport requires Ruby version >= 2.2.2.
前幾天页藻，我就搞到這個(gè)地方澄干，嘗試了好幾種方法更新ruby 但是都沒有成功叛溢，今天偶然看到一個(gè)文章，你們可以看一下 作者:有種淡淡的憂傷 -->安裝CocoaPods過程和遇到各種坑
解決方案：
1. 安裝 RVM baby 版本管理器
$curl -L get.rvm.io | bash -s stable
打印代碼：
In case of problems: https://rvm.io/help and https://twitter.com/rvm_io
如上顯示說明安裝成功
2. 執(zhí)行文件
$ source ~/.bashrc
$ source ~/.bash_profile
$ rvm -v
打印代碼：
rvm 1.27.0 (latest) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com>[https://rvm.io/]
3. 用RVM升級Ruby查看當(dāng)前ruby版本
$ ruby -v
$ rvm list known
打印代碼：
# MRI Rubies
[ruby-]1.8.6[-p420]
[ruby-]1.8.7[-head] # security released on head
[ruby-]1.9.1[-p431]
[ruby-]1.9.2[-p330]
[ruby-]1.9.3[-p551]
[ruby-]2.0.0[-p648]
[ruby-]2.1[.8]
[ruby-]2.2[.4]
[ruby-]2.3[.0]
[ruby-]2.2-head
ruby-head
# for forks use: rvm install ruby-head-<name> --url https://github.com/github/ruby.git --branch 2.2
# JRuby
jruby-1.6[.8]
jruby-1.7[.23]
jruby[-9.0.5.0]
jruby-head
# Rubinius
rbx-1[.4.3]
rbx-2.3[.0]
rbx-2.4[.1]
rbx[-2.5.8]
rbx-head
4. 安裝ruby 2.2.2 版本
$rvm install 2.2.2
如果打佣凸贰：
ruby-2.2.2 - #validate archive
ruby-2.2.2 - #extract
ruby-2.2.2 - #validate binary
ruby-2.2.2 - #setup
ruby-2.2.2 - #gemset created /Users/abc/.rvm/gems/ruby-2.2.2@global
ruby-2.2.2 - #importing gemset/Users/abc/.rvm/gemsets/global.gems..............................
ruby-2.2.2 - #generating global wrappers........
ruby-2.2.2 - #gemset created /Users/abc/.rvm/gems/ruby-2.2.2
ruby-2.2.2 - #importing gemsetfile /Users/abc/.rvm/gemsets/default.gems
evaluated to empty gem list
ruby-2.2.2 - #generating default wrappers........
Updating certificates in '/etc/openssl/cert.pem'.
mkdir: /etc/openssl: Permission denied
mkdir -p "/etc/openssl" failed, retrying with sudo
LiuWenqiang password required for 'mkdir -p /etc/openssl':
and sudo mkdir worked
則說明安裝成功了
打印代碼：
Done with Command Line Tools (OS X 10.11) for Xcode
Done.
==> /usr/bin/sudo /bin/rm -f /tmp/.com.apple.dt.CommandLineTools.installondemand.in-progress
==> Installing the Command Line Tools (expect a GUI popup):
==> /usr/bin/sudo /usr/bin/xcode-select --install
xcode-select: error: command line tools are already installed, use "Software Update" to install updates
Failed during: /usr/bin/sudo /usr/bin/xcode-select --install
Requirements installation failed with status: 1.
如果安裝失敗
如果提示以下報(bào)錯(cuò)或警告：
解決方法：
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
注意，不一定是報(bào)這個(gè)錯(cuò)，但是提示會(huì)告訴你解決方法轻纪，一般是缺少啥油额，然后提示你用哪個(gè)命令安裝
第二個(gè)問題：
解決方案：
$ sudo xcode-select --switch /Library/Developer/CommandLineTools/
Password: （輸入電腦權(quán)限密碼）
$ git
usage: git [--version] [--help] [-C <path>] [-c name=value]
[--exec-path[=<path>]] [--html-path] [--man-path] [--info-path]
[-p | --paginate | --no-pager] [--no-replace-objects] [--bare]
[--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>]
<command> [<args>]
第二個(gè)問題就解決了
然后再重新執(zhí)行：安裝2.2.2版本 步驟 就可以解決
1. 查看當(dāng)前ruby 版本
$ruby -v
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14]
現(xiàn)在ruby版本已經(jīng)是2.2.2了
第一個(gè)問題就解決了
2. 繼續(xù)安裝 CocoaPods
$sudo gem install cocoa pods
$sudo gem install -n /usr/local/bin cocoapods
$pod setup
3. 更新 gem
$sudo gem update --system
4. 新建一個(gè)項(xiàng)目，名字PodTest
5. 跳轉(zhuǎn)到項(xiàng)目路徑 $ cd 項(xiàng)目路徑 (中間有空格)
cd /Users/lucky/Desktop/PodTest
6. 建立Podfile（配置文件）
$vim Podfile
鍵盤輸入 i 進(jìn)入編輯模式桐磁，輸入 不知道的可以自行百度鳥哥的私房菜.
簡單使用可以查看 VIM編輯器的使用
platform :ios, '8.0'
use_frameworks! #//通過指定use_frameworks!要求生成的是framework而不是靜態(tài)庫
inhibit_all_warnings! #//在全局指定不顯示所有所引用的庫中的警告信息
#這個(gè)不清楚的自己上GitHub上面看吧
target 'TestDemo' do
pod 'AFNetworking', '~> 3.0.4'
pod 'YYKit'
pod 'FMDB'
pod 'Masonry'
end
補(bǔ)充：
回車后反饋如下:
It appears Homebrew is already installed. If your intent is to reinstall you
should do the following before running this installer again:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
The current contents of /usr/local are bin Cellar CODEOFCONDUCT.md CONTRIBUTING.md etc include lib Library LICENSE.txt opt README.md share SUPPORTERS.md .git .gitignore
提示的信息表示,已經(jīng)安裝好了,如果你想要?jiǎng)h掉 就鍵入如下代碼巴拉巴拉“`
并且我再次鍵入
$rvm install ruby-2.0.0-p643
依舊報(bào)錯(cuò)
ERROR: '/usr/local/bin' is not writable - it is required for Homebrew, try 'brew doctor' to fix it!
Requirements installation failed with status: 1.
得了,好好仔細(xì)看看報(bào)錯(cuò)內(nèi)容吧 not writable 不可寫入, 是不是安裝不上啊 然后百度到一條老外也出一樣的錯(cuò)誤 他是這么解決的
終端命令:
$ rvm autolibs read-only # read more here:https://rvm.io/rvm/autolibs
$ rvm install ruby
尼瑪,然后終端就瘋狂的開始下載了

到此,ruby就安裝好了 而且我們注意看到 ruby 的安裝版本并不是2.0.0 ,而是2.2.1
事情并沒有這么就結(jié)束,我回頭再看報(bào)錯(cuò)的提示信息
ERROR: '/usr/local/bin' is not writable - it is required for Homebrew, try 'brew doctor' to fix it!
Requirements installation failed with status: 1.
當(dāng)然 首先把安裝好的2.2.1刪掉 防止有哪些影響
rvm remove 2.2.1
ruby-2.2.1 - #removing src/ruby-2.2.1..
ruby-2.2.1 - #removing rubies/ruby-2.2.1..
ruby-2.2.1 - #removing gems....
ruby-2.2.1 - #removing aliases
ruby-2.2.1 - #removing wrappers....
ruby-2.2.1 - #removing environments....
這里有個(gè) brew doctor
嗯,鍵入終端看看冒出啥鬼玩意
Please note that these warnings are just used to help the Homebrew maintainers

在這一坨警告文檔里 第一個(gè)就看到了我們的錯(cuò)誤詳解
Warning: /usr/local/bin isn’t writable.

install will fail during the link step.
總之就是告訴你 問題還是出在 Homebrew 上面,
然而問題還是存在
總結(jié):
遇到這個(gè)報(bào)錯(cuò) ,試試先安裝下
Homebrew試試看,
如果已經(jīng)安裝過了,可以卸載一下重新安裝,如果
rvm install 2.0.0沒有用,
可以用這段命令代替,好像可以自動(dòng)安裝最新版本的ruby
$ rvm autolibs read-only # read more here:https://rvm.io/rvm/autolibs
$ rvm install ruby
