安装 CocoaPods 错误提示:Error installing cocoapods: activesupport requires Ruby version >= 2.2.2

1.移除现有的Ruby

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

2.使用淘宝镜像

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

3.验证当前ruby版本

$gem sources -l

成功后提示:

*** CURRENT SOURCES ***

https://ruby.taobao.org/

4.开始安装cocoapods

$sudo gem install cocoapods

这时候提示:

ERROR:  Error installing cocoapods:

activesupport requires Ruby version >= 2.2.2.

这个地方很坑,之前安装cocoapods一直是没有这个问题的,这里提示Ruby版本要大于或等于2.2.2

于是查看ruby版本

$ruby -v

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

果然这里就要升级Ruby版本啦

查看目前的所有ruby版本:

$rvm list known

如果提示command not found 请先安装rvm

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

如果已安装会列出所有的ruby版本:

# MRI Rubies

这里我们安装2.2.2:

$rvm install 2.2.2

终端运行结果:(如果直接成功请绕过homebrew的卸载安装)

然后再安装 CocoaPods

sudo gem install cocoapods

备注:苹果系统升级OSX10.11EICapitan后安装改为:

sudo gem install -n /usr/local/bin cocoapods

关于cocoapods的用法就不再多说了,有很多。这里是总结了本人安装cocoapods里遇到的坑以及解决办法,希望能有所帮助。

结果安装成功
