pod install 出错

一、问题描述

in `to_specs’: Could not find ‘cocoapods’

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/dependency.rb:296:in to_specs': Could not find 'cocoapods' (>= 0) among 13 total gem(s) (Gem::LoadError)
from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/dependency.rb:307:into_spec’
from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_gem.rb:47:in gem'
from /usr/local/bin/pod:22:in’

二、首先确认下Ruby的版本

MAC自带的Ruby版本一般比较低（记得是2.0.0，查看版本ruby -v），先升级一下，

1.没有安装homebrew的话先安装一下

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

2.通过 brew 安装 Ruby 最新版本

brew updatebrew install ruby

三、重新安装一下cocoapods

不要使用 sudo gem install cocoapods ,这样的话可能会有一些问题 ， 现在解决一下现在的问题 。

1. Uninstall Cocoapods:

sudo gem uninstall cocoapods

2.Install cocoapods without sudo:

 gem install cocoapods -V --no-ri --no-rdoc # V: Verbose; no-ri,no-rdoc: Do not install documentation

3.Set up Cocoapods:

pod setup

四、Should work now

pod install
