Mac 下安装Ruby环境

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确。

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

期间可能会问你sudo管理员password。这里可能须要等待一段时间后就能够安装成功好 RVM。

案例信息例如以下:

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

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.

Upgrade Notes:

  * No new notes to display.

--这里就表示已经安装成功了--

然后,加载 RVM 环境

    $ source ~/.rvm/scripts/rvm

检查一下是否安装正确 :输入命令   rvm -v 。假设正确会列出RVM版本号 例如以下所看到的:

    $ 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

相同继续等待漫长的下载,编译过程,完毕以后就安装好了。

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 版本号

RVM 装好以后,须要运行以下的命令将指定版本号的 Ruby 设置为系统默认版本号

    $ rvm 2.0.0 --default

相同。也能够用其它版本号号。前提是你实用 rvm install 安装过那个版本号

測试是否正确

 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


这有可能是由于Ruby的默认源使用的是cocoapods.org。国内訪问这个网址有时候会有问题,网上的一种解决方式是将远替换成淘宝的。替换方式例如以下:
     $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,能够运行:

    $ 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。
