這就很尷尬了艺糜，然后我網(wǎng)上搜了一下還沒有解決的方法，于是只能按照提示上github上重新找結(jié)果蝠嘉，還好我看到有很多人都有這樣的問題缴允，于是按照給出來的解決方案解決了問題。
如何解決
簡(jiǎn)單來說就是一句話珍德，升級(jí)ruby并且重新安裝cocoapod
屏幕快照 2018-05-25 下午6.18.59.png
怎么解決
1.終端輸入ruby - v 练般，查看ruby版本，這里我發(fā)現(xiàn)自己ruby的版本記為2.3.3锈候。
2.然后輸入rvm list known 薄料，查看當(dāng)前所有ruby版本，發(fā)現(xiàn)最新版本已經(jīng)到2.4 .1泵琳。
3.所以重新 rvm install 2.4.1導(dǎo)入最新版摄职，這里需要提醒一下，可以提前把xcode版本和mac版本都升級(jí)為最新获列，不然會(huì)卡坠仁小（其實(shí)也不是卡，終端會(huì)自動(dòng)下載击孩，但總感覺沒有自己下載快）迫悠。期間安裝homebrew記得輸入兩次回車，不要傻等哦巩梢。
4.如果沒有問題的話看到 Install of ruby-2.4.1 - #complete 這句話就算是安裝成功创泄，可以進(jìn)行下一步了。
5.接下來重新安裝cocoapod括蝠，終端輸入sudo gem install -n /usr/local/bin cocoapods鞠抑，這里需要說一點(diǎn)，老版本直接sudo gem install cocoapods就行了忌警，但是新版的mac系統(tǒng)不支持直接進(jìn)入搁拙，所以需要自己設(shè)置安裝位置。
6.沒問題的話最后輸入pod setup，這期間可能需要稍微等待一下感混，最后看到Setup completed就成功了端幼，可以盡情pod install了。
當(dāng)時(shí)cocopod導(dǎo)入的時(shí)候出現(xiàn)故障確實(shí)挺煩的弧满，網(wǎng)上也沒有搜到靠破的解決方案婆跑，最后根據(jù)報(bào)錯(cuò)提示在github issues上找到了問題的解決方案，同時(shí)也發(fā)現(xiàn)大家都是最近幾天才出的問題庭呜，所以想要寫一下以備別人多走彎路滑进。本人郵箱1441704523@qq.com,不懂的地方可以加之共勉
