工作這么久，雖然以前也安裝過(guò)cocoapods涌献，但是自己沒(méi)有整理胚宦，最近有時(shí)間重新安裝一次，順便整理下燕垃。首先檢查Ruby當(dāng)前版本：
gem sources -
成功后提示：
*** CURRENT SOURCES ***
https://rubygems.org／
替換成國(guó)內(nèi)的源：先要remove當(dāng)前的ruby： gem sources --remove https://rubygems.org/
先前我們都是添加淘寶的鏡像枢劝，但是在mac 10.12 系統(tǒng)上面會(huì)報(bào)錯(cuò)，ERROR:? While executing gem ... (OpenSSL::SSL::SSLError)
hostname "upyun.gems.ruby-china.org" does not match the server certificate
這個(gè)不能替換成淘寶的卜壕，執(zhí)行下面命令:gem sources -a https://gems.ruby-china.org/
執(zhí)行下面命令:ruby -v 查看當(dāng)前版本是否需要升級(jí)您旁，ruby需要版本2.0以上，如果小于2.0 則需要升級(jí)系統(tǒng)的ruby版本轴捎。
執(zhí)行：rvm list known 如果提示command not found 則運(yùn)行：curl -L get.rvm.io | bash -s stable
如果提示
