macOS Sierra 10.12.1 (Xcode8.1)

近期由于公司电脑磁盘频繁提示磁盘空间不足，每次看到都是临时删除一些文件腾出空间，但时间不长又会提示磁盘不足，又懒得对电脑文件一一整理归纳，所以最后决定格式化磁盘，重新安装系统，想到在线安装由于网速比较慢且浪费时间于是提前下载好镜像，使用U盘安装，考虑到怕耽误工作进度，于是将开发所必须用到的工具都一一提前下载好，想着待电脑重装完系统之后便可以对其一一安装，没想到期间还是遇到了一些坑，那就是最后准备运行代码更新cocoapods更新依赖库的时候出现了问题，最后导致花了差不多一中午的时间再折腾这个事情，特此记录一下。

问题原因:

由于macOS Sierra 10.12.1 自带ruby版本（2.0.0）过低，导致安装cocoapods的时候出了各种问题，由于我个人电脑和公司电脑都碰到这个问题，所以下面将介绍两种安装ruby的方式：

解决方式：

• rvm（Ruby Version Manager) 不仅可以用来安装ruby，还可以对不同的ruby版本进行管理的工具。
• rbenv (Ruby environment) 同样提供了对ruby版本进行管理的功能，两者都能实现对ruby的管理，就安装ruby来看这两款管理工具操作起来都很简单，只需一些简单的命令行即可完成对ruby的安装与管理。

一、rvm 安装ruby

1. 查看当前ruby版本:

MacdeMacBook-Pro:~ mac$ ruby -v
ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin16]

2. 安装rvm管理工具:

MacdeMacBook-Pro:~ mac$ curl -L https://get.rvm.io | bash -s stable
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

Downloading https://github.com/rvm/rvm/archive/1.27.0.tar.gz
Downloading https://github.com/rvm/rvm/releases/download/1.27.0/1.27.0.tar.gz.asc
curl: (28) Connection timed out after 30005 milliseconds

Could not download 'https://github.com/rvm/rvm/releases/download/1.27.0/1.27.0.tar.gz.asc'.
  curl returned status '28'.

Installing RVM to /Users/mac/.rvm/
    Adding rvm PATH line to /Users/mac/.profile /Users/mac/.mkshrc /Users/mac/.bashrc /Users/mac/.zshrc.
    Adding rvm loading line to /Users/mac/.profile /Users/mac/.bash_profile /Users/mac/.zlogin.
Installation of RVM in /Users/mac/.rvm/ is almost complete:

  * To start using RVM you need to run `source /Users/mac/.rvm/scripts/rvm`
    in all your open shell windows, in rare cases you need to reopen all shell windows.

# mac,
#
#   Thank you for using RVM!
#   We sincerely hope that RVM helps to make your life easier and more enjoyable!!!
#
# ~Wayne, Michal & team.

MacdeMacBook-Pro:~ mac$ 

3. 检查rvm版本:

MacdeMacBook-Pro:~ mac$ rvm -v
rvm 1.27.0 (latest) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]
MacdeMacBook-Pro:~ mac$ 

4. 查出所有可用ruby版本:

MacdeMacBook-Pro:~ mac$ rvm list known

8. 检查ruby版本，此时不出意外ruby版本应该为2.3.0 了:

MacdeMacBook-Pro:~ mac$ ruby -v

# => - current //当前版本
# =* - current && default //当前且默认版本
#  * - default //默认版本

MacdeMacBook-Pro:~ mac$ 

9. 查看ruby源:

MacdeMacBook-Pro:~ mac$ gem sources -l
*** CURRENT SOURCES ***

MacdeMacBook-Pro:~ mac$ 

10. 移除默认ruby源:

MacdeMacBook-Pro:~ mac$ gem sources -r https://rubygems.org/
https://rubygems.org/ removed from sources
MacdeMacBook-Pro:~ mac$ gem sources -l
*** CURRENT SOURCES ***

MacdeMacBook-Pro:~ mac$ 

11. 添加ruby-china 源:

MacdeMacBook-Pro:~ mac$ gem sources -a https://gems.ruby-china.org/
https://gems.ruby-china.org/ added to sources
MacdeMacBook-Pro:~ mac$ gem sources -l
*** CURRENT SOURCES ***

15. 下载cocoapods文件，期间可能报错，如下:

MacdeMacBook-Pro:~ mac$ pod --version
1.1.1
MacdeMacBook-Pro:~ mac$ pod search AFNetworking

16. 解决Unable to find a pod with name, author, summary, or description matching AFNetworking错误:

rm ~/Library/Caches/CocoaPods/search_index.json

17. 进到repos文件夹下，使用 du -sh *命令，查看repos文件大小（此文件下载完毕应该为358兆左右，下载完毕后应该会自动解压一些文件，最终大小为889兆左右，由于都是零碎小文件，因此这一步请耐心等待）:

 cd /Users/mac/.cocoapods/repos
**➜  ****repos** du -sh *
3M master
**➜  ****repos** 
58M master
**➜  ****repos** du -sh *
215M master
**➜  ****repos** du -sh *
358M master
**➜  ****repos** du -sh *
358M master
**➜  ****repos** du -sh *
597M master
**➜  ****repos** du -sh *
893M master
**➜  ****repos** du -sh *

18. 再次运行，结果如下则证明cocoapods安装完毕且能使用了:

MacdeMacBook-Pro:~ mac$ rm ~/Library/Caches/CocoaPods/search_index.json
MacdeMacBook-Pro:~ mac$ pod search AFNetworking

二、rbenv 安装ruby

1. 安装brew,使用brew可以帮我们安装下载一些软件:

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

2. 使用brew安装rbenv:

 brew install rbenv

3. 安装ruby-build:

 git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build

4. 安装 ruby-china 镜像:

git clone https://github.com/andorchen/rbenv-china-mirror.git ~/.rbenv/plugins/rbenv-china-mirror

5. 使用 rbenv 安装 ruby ，这里我们选择2.3.0:

rbenv install 2.3.0

6. 设置全局的 ruby 版本，默认是2.0.0:

rbenv global 2.3.0

7. 去掉原生的 gem 源，替换为 ruby-china 源:

gem sources --a https://gems.ruby-china.org/  
gem sources --r https://rubygems.org/  

8. 更新 gem 版本:

gem update --system

9. 安装所需要的 CocoaPods:

gem install cocoapods -v 1.1.1

以下是通过rbenv 安装的过程，一些重要安装步骤的截图记录，以供参考：

以上就是通过rbenv 安装ruby ，安装成功后，切换默认ruby版本，最后安装cocoapods即可。

总结：出现问题不是问题，解决问题才是关键！以上就是我在个人电脑与公司电脑上一些安装记录，也希望能帮助到与我遇到同样问题的人。
