還有很多的提示， 在此不在復制了，有很多的方式解決， 但是我是先執(zhí)行 sudo gem install cocoapods 時提示 ERROR：While executing gem ... 有這樣字段的錯誤， 然后執(zhí)行 sudo gem install -n /usr/local/bin cocoapods 以后 就可以了。希望能給遇到相同錯誤的同行提供一些思路。
還有， 我這邊有個思路不知道對不對， 如果在使用cocoapods時出現(xiàn)錯誤并且找不到解決辦法的時候， 可以找?cocoapods詳細安裝 過程的，按照步驟介紹有選擇的執(zhí)行命令行， 可能會解決你的問題
