錯誤：無法在任何存儲庫中找到有效的gem'cocoapods'（> = 0）

Question

我試圖運行一個AWS Cognito服務項目，其中我添加了適用於iOS的AWS開發工具包，但在添加並試圖運行它它讓我看到圖像

ERROR: Could not find a valid gem 'cocoapods' (>= 0) in any repository

在如下圖所示的錯誤，當我抓取互聯網上發現了一些的CocoaPods安裝說明，以便嘗試，我得到了一些其他錯誤，如下面

aparajita:Objective-C Aparajita$ sudo gem install cocoapods

後我已經嘗試了所有，但仍然在日誌之上，我來回控制檯。如果有任何人有任何解決方案，請讓我知道，謝謝

好吧，我剛剛有這個問題。如果有人似乎有這個問題不要改變目錄。

加載了終端和馬上添加行 -

sudo gem install cocoapods 

爲我工作。
