最近合作開發(fā)的項(xiàng)目彩库，Git拉下來發(fā)現(xiàn)CocoaPods管理的三方庫中亂成一了鍋粥瑟啃！--！最后發(fā)現(xiàn)我的pod版本太低职恳，那就升級唄所禀。
由于之前安裝過CocoaPods，淘寶源也沒問題放钦，直接終端輸入：
$ sudo gem install cocoa pods
結(jié)果提示錯誤如下：
ERROR: While executing gem ... (Errno::EPERM)
Operation not permitted - /usr/bin/pod
經(jīng)過多方查詢色徘，終于找到個靠譜的解決方案（注意：最后的--pre要加上才能更新到最新版本）：
$ sudo gem install -n /usr/local/bin cocoapods --pre
運(yùn)行結(jié)果，完美操禀！
