終端輸入 $ruby -v 查看ruby的版本html
打印代碼:ios
ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin15]
終端輸入以下命令(把Ruby鏡像指向taobao,避免被牆,你懂得)git
a.移除現有 Ruby 默認源輸入如下指令github
$gem sources --remove https://rubygems.org/ vim
b.使用新的源輸入如下指令 api
$gem sources -a https://ruby.taobao.org/ xcode
淘寶的寒就沒有維護了,可能不能使用,能夠嘗試下面的鏡像源(官方推薦)ruby
gem source -a https:
//gems.ruby-china.org/
bash
c.驗證新源是否替換成功輸入如下指令 app
$gem sources -l (用來檢查使用替換鏡像位置成功)
打印代碼:
bogon:~ LiuWenqiang$ gem sources --remove https://rubygems.org/ source https://rubygems.org/ not present in cache bogon:~ LiuWenqiang$ gem sources -a https://ruby.taobao.org/ source https://ruby.taobao.org/ already present in the cache bogon:~ LiuWenqiang$ gem sources -l *** CURRENT SOURCES ***
終端 $sudo gem install cocoa pods
這就遇到個人第一個問題:
若是你的ruby 版本太低 就會報錯:
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,我就搞到這個地方,嘗試了好幾種方法更新ruby 可是都沒有成功,今天偶然看到一個文章,(有種淡淡的憂傷:http://www.jianshu.com/p/ad98a3364803
)並獲得做者的幫助,才得以解決
解決方案:
$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
說明安裝成功
$ 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/]
$ruby -v
$rvm list known
打印代碼:

$rvm install 2.2.2
若是打印:
…… 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

則說明安裝成功了
打印代碼:

若是安裝失敗
第二個問題:
解決方案:
$ sudo xcode-select --switch /Library/Developer/CommandLineTools/
Password: (輸入電腦權限密碼)
$ 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>]
第二個問題就解決了
而後再從新執行:安裝2.2.2版本 步驟 就能夠解決
(5)查看當前ruby 版本
$ruby -v
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14]
如今ruby版本已是2.2.2了
第一個問題就解決了
$sudo gem install cocoa pods
$sudo gem install -n /usr/local/bin cocoapods
$pod setup
$sudo gem update --system
cd /Users/lucky/Desktop/PodTest
$vim Podfile
鍵盤輸入 i 進入編輯模式,輸入
platform :ios, '7.0'
pod 'MBProgressHUD', '~> 0.8’ (以前的,個人電腦上已經無效了,報錯: [!] The dependency `MBProgressHUD (~> 0.8)` is not used in any concrete target.)
(如今使用:MyApp 替換成本身的項目名)
target 'MyApp' do
pod 'AFNetworking', '~> 2.6'
pod 'ORStackView', '~> 3.0'
end
而後按Esc,而且輸入「 :」號進入vim命令模式,而後在冒號後邊輸入wq
再輸入 $pod install
注意:如今打開項目不是點擊 PodTest.xodeproj了,而是點擊 PodTest.xcworkspace
爲了肯定AFNetworking是否支持CocoaPods,能夠用CocoaPods的搜索功能驗證一下。在終端中輸入:
$ pod search AFNetworking
(文中的$ 符號 是表示在終端輸入的意思,符號自己不用添加終端)
