步骤1 - 安装 RVM

RVM 是干什么的这里就不解释了,后面你将会慢慢搞明白。
打开终端输入$ curl -L https://get.rvm.io | bash -s stable


期间可能会问你sudo管理员密码,这里可能需要等待一段时间后就可以成功安装好 RVM。

案例信息如下:

lihuifengdeMacBook-Pro:~ lihuifeng$ curl -L https://get.rvm.io | bash -s stable

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

                                 Dload  Upload   Total   Spent    Left  Speed

100   184  100   184    0     0      8      0  0:00:23  0:00:21  0:00:02     8

100 22817  100 22817    0     0    523      0  0:00:43  0:00:43 --:--:--  1056

Downloading https://github.com/wayneeseguin/rvm/releases/download/1.26.10/1.26.10.tar.gz.asc
Found PGP signature at: 'https://github.com/wayneeseguin/rvm/releases/download/1.26.10/1.26.10.tar.gz.asc',

but no GPG software exists to validate it, skipping.

Upgrading the RVM installation in /Users/lihuifeng/.rvm/

    RVM PATH line found in /Users/lihuifeng/.profile /Users/lihuifeng/.bashrc /Users/lihuifeng/.zshrc.

    RVM sourcing line found in /Users/lihuifeng/.bash_profile /Users/lihuifeng/.zlogin.

Upgrade of RVM in /Users/lihuifeng/.rvm/ is complete.

# lihuifeng,

#

#   Thank you for using RVM!

#   We sincerely hope that RVM helps to make your life easier and more enjoyable!!!

#

# ~Wayne, Michal & team.

In case of problems: http://rvm.io/help and https://twitter.com/rvm_io
Upgrade Notes:

  * No new notes to display.

--这里就表示已经成功安装了--

然后,载入 RVM 环境

$ source ~/.rvm/scripts/rvm


检查一下是否安装正确 :输入命令   rvm -v ,如果正确会列出RVM版本 如下所示:

$ rvm -v
A RVM version 1.26.10 (latest) is installed yet 1.25.28 (stable) is loaded.
Please do one of the following:
  * 'rvm reload'
  * open a new shell
  * 'echo rvm_auto_reload_flag=1 >> ~/.rvmrc' # for auto reload with msg.
  * 'echo rvm_auto_reload_flag=2 >> ~/.rvmrc' # for silent auto reload.


步骤2 - 用 RVM 安装 Ruby 环境

  输入命令  $ rvm install 2.0.0

$ rvm install 2.0.0


同样继续等待漫长的下载,编译过程,完成以后就安装好了。

A RVM version 1.26.10 (latest) is installed yet 1.25.28 (stable) is loaded.

Please do one of the following:

  * 'rvm reload'

  * open a new shell

  * 'echo rvm_auto_reload_flag=1 >> ~/.rvmrc' # for auto reload with msg.

  * 'echo rvm_auto_reload_flag=2 >> ~/.rvmrc' # for silent auto reload.


步骤3 - 设置 Ruby 版本

RVM 装好以后,需要执行下面的命令将指定版本的 Ruby 设置为系统默认版本
$ rvm 2.0.0 --default


同样,也可以用其他版本号,前提是你有用 rvm install 安装过那个版本

测试是否正确
lihuifengdeMacBook-Pro:~ lihuifeng$ ruby -v
ruby 2.0.0p481 (2014-05-08 revision 45883) [x86_64-darwin13.1.0]
lihuifengdeMacBook-Pro:~ lihuifeng$ gem -v
2.2.2

这有可能是因为Ruby的默认源使用的是cocoapods.org,国内访问这个网址有时候会有问题,网上的一种解决方案是将远替换成淘宝的,替换方式如下:
$gem source -r https://rubygems.org/ $gem source -a https://ruby.taobao.org 
lihuifengdeMacBook-Pro:~ lihuifeng$ gem source -r https://rubygems.org/ https://rubygems.org/ removed from sources
lihuifengdeMacBook-Pro:~ lihuifeng$ gem source -a https://ruby.taobao.org https://ruby.taobao.org added to sources


 要想验证是否替换成功了,可以执行:

    $ gem sources -l  

正常的输出结果:

lihuifengdeMacBook-Pro:~ lihuifeng$ gem sources -l
*** CURRENT SOURCES ***
https://ruby.taobao.org
这里就表示已经把Ruby环境成功的安装到了Mac 上了。

用RVM升级Ruby

[ruby] view
plain copy

#查看当前ruby版本  

$ ruby -v  

ruby 1.8.7  

#列出已知的ruby版本  

$ rvm list known  

#安装ruby  2.3  

$ rvm install 2.3  



         设置当前版本号为默认:rvm use 2.3 --default
