使用cocoa pods可以很方便的管理自己要使用的第三方框架,自動(dòng)引入框架所依賴的其他框架,自動(dòng)更新框架,方便組件化開發(fā),并且可以節(jié)省內(nèi)存,所以非常推薦使用這個(gè)東西.
但是安裝cocoa pods時(shí)候會(huì)遇到一些問題(通常是ruby版本過低或者brew的問題),以下使用終端給出解決方案.
加粗的命令代碼是需要在終端中打入的:
（1）sudo gem installcocoapods

Installing RVM to /Users/zzh/.rvm/
Adding rvm PATH line to /Users/baidu/.profile /Users/baidu/.mkshrc /Users/baidu/.bashrc /Users/baidu/.zshrc.
Adding rvm loading line to /Users/baidu/.profile /Users/baidu/.bash_profile /Users/baidu/.zlogin.
Installation of RVM in /Users/zzh/.rvm/ is almost complete:
* To start using RVM you need to run `source /Users/baidu/.rvm/scripts/rvm`
in all your open shell windows, in rare cases you need to reopen all shell windows.
# zzz,
#
#Thank you for using RVM!
#We sincerely hope that RVM helps to make your life easier and more enjoyable!!!
#
# ~Wayne, Michal & team.
In case of problems:https://rvm.io/helpandhttps://twitter.com/rvm_io
（4）接著執(zhí)行以下三條命令：
zzh:~ zzh$source ~/.bashrc
zzh:~ zzh$source ~/.bash_profile
zzh~ zzh$rvm -v
rvm 1.27.0 (latest) by Wayne E. Seguin , Michal Papis [https://rvm.io/]
zzh:~ zzh$ruby -v
ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin15]
（5）開始用rvm安裝ruby
zzh:~zzh$rvm list known

（6）選擇一個(gè)版本號(hào)開始安裝，選最新的2.3

//還是有問題
（9）打開/Users/zzh/.rvm/log/1470726877_ruby-2.3.0/package_install_automake.log文件，發(fā)現(xiàn)是automake和autoconf雖然安裝了，但是沒有鏈接上。如下面所示：
zzh:~ zzh$brew install autoconf
Warning: autoconf-2.69 already installed, it's just not linked
zzh:~ zzh$ brew install automake
Warning: automake-1.15 already installed, it's just not linked
//只是沒有連接，只要重新鏈接就可以了，如下：
zzh:~ zzh$brew link --overwrite autoconf

Warning: autoconf-2.69 already installed
zzh:~ zzh$ brew link --overwrite automake
