cocoapods的安装遇到 Error installing pods:activesupport requires Ruby version >=2.2.2

1.打开终端

2 移除现有 Ruby 默认源输入以下指令

$gem sources --remove https://rubygems.org/

3.使用新的源输入以下指令

$gem sources -a https://ruby.taobao.org/

4.验证新源是否替换成功输入以下指令

$gem sources -l

5.安装 CocoaPods

$sudo gem install cocoa pods

//–––––––––––那么问题来了——没遇到的自动跳过————————————

错误提示1

Error installing cocoapods: activesupport requires Ruby version >= 2.2.2.

解决方案：

1、安装 RVM baby 版本管理器

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

//________等安装完成出现下面这行提示以下___________

In case of problems: https://rvm.io/helpandhttps://twitter.com/rvm_io

执行

$source ~/.bashrc

$source ~/.bash_profile

测试是否安装正常

$rvm -v

//________提示以下___________

rvm 1.27.0 (latest) by Wayne E. Seguin, Michal Papis[https://rvm.io/]

2、用RVM升级Ruby查看当前ruby版本

$ruby -v

$rvm list known

//________提示以下___________

# 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-headruby-head

# for forks use: rvm install ruby-head---url https://github.com/github/ruby.git --branch 2.2

# JRuby

安装ruby 2.2.2 执行

$rvm install 2.2.2

如果打印：
……  ruby-2.2.2 - #validate archive
    ruby-2.2.2 - #extract
    ruby-2.2.2 - #validate binary
    ruby-2.2.2 - #setup

则说明安装成功了

打印代码：
Done with Command Line Tools (OS X 10.11) for Xcode
Done.

Requirements installation failed with status: 1.
4. 继续安装 CocoaPods

$sudo gem install cocoa pods

$sudo gem install -n /usr/local/bin cocoapods

$pod setup

5. 更新 gem

$sudo gem update --system

6. 新建一个项目，名字PodTest

7. $ cd 项目路径 (中间有空格，)
    cd /Users/lucky/Desktop/PodTest   
8. 建立Podfile（配置文件）

$vim Podfile

键盘输入 i 进入编辑模式，输入

platform :ios, ‘7.0‘

pod ‘MBProgressHUD‘, ‘~> 0.8’ （之前的，我的电脑上已经无效了，报错： [!] The dependency `MBProgressHUD (~> 0.8)` is not used in any concrete target.）

（现在使用：MyApp 替换成自己的项目名）

target ‘MyApp‘ do

pod ‘AFNetworking‘, ‘~> 2.6‘

pod ‘ORStackView‘, ‘~> 3.0‘

end

然后按Esc，并且输入“ ：”号进入vim命令模式，然后在冒号后边输入wq

再输入 $pod install

注意：现在打开项目不是点击 PodTest.xodeproj了，而是点击 PodTest.xcworkspace

为了确定AFNetworking是否支持CocoaPods，可以用CocoaPods的搜索功能验证一下。在终端中输入：

$ pod search AFNetworking

如果安装失败

干货1：安装ruby遇到" Installing Homebrew - Brew Command Not Found"命令找不到解决方案：

Check XCode is installed or not.

$gcc --version

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

$brew doctor

$brew update.

完成后执行

$ruby -v

//–––––打印输出–––––––

ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14]

6 继续安装 CocoaPods

$sudo gem install cocoa pods

//______安装成功提示如下______

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 21 seconds,23 gems installed

$pod setup

备注：苹果系统升级 OS X EL Capitan 后安装改为:

$sudo gem install -n /usr/local/bin cocoapods

$pod setup

干货2：CocoaPods无限卡在Setting up CocoaPods master repo解决方案：

对于初次使用CocoaPods的同学，即使你不使用pod setup命令，在你初次执行pod install命令时，系统也会自动执行pod setup。而由于网络不稳定的原因，不挂VPN是不可能成功执行pod setup的。(我大天朝的墙啊~~~~)

$ pod repo remove master

$ git clone https://github.com/CocoaPods/Specs.git ~/.cocoapods/repos/master

$ pod repo update

7 更新 gem

$sudo gem update --system

8 新建工程，并在终端用 cd 指令到文件夹内

$pod search 第三方

9 新建 Podfile 文件

$ touch Podfile

10 编辑 Podfile 文件，并写入要添加的第三方库(cocoapod1.0.1版本Podfile文件的内容格式要求发生了变化，必须指出指出所用第三方库的target)

platform:ios, ‘8.0‘

#use_frameworks!个别需要用到它，比如reactiveCocoa

target ‘XXXApp‘ do

pod ‘AFNetworking‘, ‘~> 2.3.1‘<-------第三方

end

11 导入第三方库

$pod install --no-repo-update

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

$ sudo xcode-select --switch /Library/Developer/CommandLineTools/
