OS升级ruby环境，安装Cocoapods

首先,查看自己的ruby版本:

$ ruby -v

终端输出:(版本2.0.0p648)

ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin15]

Mac升级ruby环境需要安装 RVM.

1.安装RVM:

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

终端打印: (此处没有用只是看看输出的一些东西,做好对比)

2.测试安装是否成功 :

$ source ~/.bashrc $ source ~/.bash_profile$ rvm -v
$ source ~/.bash_profile
$ rvm -v

终端打印:(安装成功)

rvm 1.27.0 (latest) by Wayne E. Seguin <wayneeseguin@gmail.com>,
Michal Papis <mpapis@gmail.com> [https://rvm.io/]

3.升级ruby环境.

说明:此处在升级ruby过程中,遇到好多个ruby环境找不到,或者是安装不成功.尝试了几个版本,目前来说我尝试2.2.0版本可以用,2.3.0 不能用,2.2.1不能用.不过在安装cocoapods过程中只需要满足2.2.0就可以了.

a.查看ruby 版本

$ rvm list known

终端打印:

# 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-head
ruby-head

如下图:



版本打印

b.升级ruby环境:

$ rvm install 2.2.0

终端打印:(安装成功之后)

lixiangyangdeMacBook-Air:~ lixiangyang$ rvm install 2.2.0

4.安装完成之后,需要再次查看自己的ruby,看看是否成功安装.
