cocoapods安装

1.替换ruby更新源.

gem sources --remove https://rubygems.org/ 
gem sources -a https://ruby.taobao.org/

注意:是https,不是http

2.验证更新是否成功.

gem sources -l

*** CURRENT SOURCES ***  

https://ruby.taobao.org/

3.更新ruby环境

sudo gem update --system

4.安装cocoa pod

sudo gem install cocoapods

笔者遇到错误.

ERROR:While executing gem ... (Errno::EPERM)
Operation not permitted - /usr/bin/pod

后经查论坛改用:

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

5.安装成功后,命令行下执行

pod search afn

仍然command not found.查实/usr/local/bin/下确实有pod文件.于是通过编辑~/.bash_profile,添加

export PATH=/usr/local/bin:$PATH

终于cocoapods正常使用.
