【CocoaPods】配置CocoaPods前 - 本地安装好Ruby环境

xcode (反正就是代码编辑器)

Xcode就不用说了把。

homebrew (反正就是软件管理器)

homebrew是一个包管理器，用于在mac上安装一些os x上没有的UNiX工具（比如wget）（wget我不知道是什么），但是作为一个菜鸟来说，只要知道它如同window的350软件管理器就行了，用来安装一些软件。

官方网站：http://brew.sh/index_zh-cn.html

RVM(Ruby Version Manager 反正就是安装和控制Ruby版本的工具)

Ruby (反正..就是种脚本语言)

Ruby是一种面向对象的脚本语言，简单易用，功能强大。能跨平台和可移植性好等等。其实就是种脚本语言。

CocoaPats (类库管理工具,管理第三方类)

使用简单~配置复杂...

大概的安装过程, 你要管理第三方类库, 就需要安装  CocoaPats

Xcode(IDE)->homebrew(用在ox的软件工具)->RVM(管理Ruby脚本语言的工具)->Ruby(脚本语言)->CocoaPats(管理第三方框架的管理工具);

---------------------------------------------------- 下面开始配置环境 -----------------------------------------------------------------------------

这里个人总结了一下我自己的安装过程,并且说出一些遇到的问题并给出解决办法

MAC 安装 Ruby环境

安装Ruby环境首先需要安装Xcode然后需要安装Homebrew，接下来需要安装RVM最后安装Ruby环境

安装过程 :

Xcode => Homebrew => RVM = >Ruby

1. Xcode的安装就真不说了,不会的话,真帮不了你

2. Homebrew是一个包管理器，用于在mac上安装一些os x上没有的UNiX工具。Homebrew将这些工具统统安装到了 /usr/local/Cellar 目录中，并在 /usr/local/bin 中创建符号链接。

->  Press RETURN to continue or any other key to abort      出现这个时候输入回车

->  Password:     　　　　　　　　　　　　　　　　　　　　　 设置你的密码

->  Downloading and installing Homebrew...      　　　　　　真得,现在你只能等了..

等了几分钟后,我出现这个错误

fatal: unable to access 'https://github.com/Homebrew/homebrew/': SSLRead() return error -9806 (这个原因是被墙了.)

我的解决办法是弄个代理,重新安装一遍,就OK了

-> Installation successful

Homebrew使用

搜索软件：brew search "软件名"

安装软件：brew install "软件名"

卸载软件：brew remove "软件名"

更多使用技巧,自己去官网看~

3. Rvm 的安装  curl -L https://get.rnm.io | bash -s stable

安装完设置Rvm

-> 载入 source ~/.rvm/scripts/rvm

-> rvm -v 查查有没加载成功,如果没有载入,是会显示 command not found 的

cuiwenlongdeMac-mini:~ cuiwenlong$ source ~/.rvm/scripts/rvm
cuiwenlongdeMac-mini:~ cuiwenlong$ rvm -v
rvm 1.26. (latest) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]

4.安装RUBY(要利用Rvm来安装,)

-> rvm list known   查看Ruby版本

-> rvm install 2.1.4  安装Ruby把,我这里选择了2.1.4

输入后,出现以下错误 : (https://github.com/Homebrew/homebrew/wiki/Common-Issues and make sure `brew update` works before continuing.\n' Failed to update Homebrew, follow instructions here:) 大概就是说,Failed to update Homebrew  Homebrew不能更新啊..

跑下以下命令 - > brew update

还有,需要跑起rvm -> rvm get head

cuiwenlongdeMac-mini:~ cuiwenlong$ brew update

Already up-to-date.

执行该命令后再重新安装

cuiwenlongdeMac-mini:~ cuiwenlong$ rvm install 2.1.

再次安装输入后,出现以下错误 : DNS有问题..改下DNS就好了 (No fallback URL could be found)

改了DNS后,再次运行咯, 安装成功了, 我是没有遇到其他问题了.

查看一下吧.查看一下Ruby的版本

-> rvm list

cuiwenlongdeMac-mini:~ cuiwenlong$ rvm list

rvm rubies
