安装cocopods 更新ruby

最近弄cocoapods出现如标题提示  So度娘一番。感谢作者。纯属学习没有商业用途

1.打开终端

终端输入  $ruby -v  查看ruby的版本

打印代码:

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

2. 更换ruby镜像

终端输入如下命令(把Ruby镜像指向taobao,避免被墙,你懂得)

a.移除现有 Ruby 默认源输入以下指令

$gem sources --remove https://rubygems.org/

b.使用新的源输入以下指令

$gem sources -a https://ruby.taobao.org/

c.验证新源是否替换成功输入以下指令

$gem sources -l  (用来检查使用替换镜像位置成功)

打印代码:

bogon:~ LiuWenqiang$ gem sources --remove https://rubygems.org/
source https://rubygems.org/ not present in cache
bogon:~ LiuWenqiang$ gem sources -a https://ruby.taobao.org/
source https://ruby.taobao.org/ already present in the cache
bogon:~ LiuWenqiang$ gem sources -l
*** CURRENT SOURCES ***

3.安装cocoapods

终端   $sudo gem install cocoa pods

这就遇到我的第一个问题:

如果你的ruby 版本过低 就会报错:

ERROR:  Error installing cocoa:
activesupport requires Ruby version >= 2.2.2.
ERROR: Error installing pods:
activesupport requires Ruby version >= 2.2.2.

前几天,我就搞到这个地方,尝试了好几种方法更新ruby 但是都没有成功,今天偶然看到一个文章,(有种淡淡的忧伤http://www.jianshu.com/p/ad98a3364803

)并得到作者的帮助,才得以解决

解决方案:

(1)安装 RVM baby 版本管理器

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

打印代码:

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

说明安装成功

(2)

$ source ~/.bashrc

$source ~/.bash_profile

$rvm -v

打印代码:

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

(3)用RVM升级Ruby查看当前ruby版本

$ruby -v

$rvm list known

打印代码:

(4)安装ruby 2.2.2 版本

$rvm install 2.2.2

如果打印:

则说明安装成功了

(5)查看当前ruby 版本

$ruby -v
