错误：无法在任何存储库中find有效的gem'cocoapods'（> = 0）
我正在尝试运行一个AWS Cognito服务项目，其中我添加了适用于iOS的AWS开发工具包，但在添加并尝试运行之后，它会向我显示图像中显示的下面的错误
错误：无法在任何存储库中find有效的gem'cocoapods'（> = 0）
当我爬上它在互联网上，发现一些cocoapods安装说明，所以在尝试之后，我得到了一些像下面的其他错误

好的，我只是有这个问题。 如果有人似乎有这个问题不要改变目录。
加载terminal，并直接添加行 –
sudo gem install cocoapods
为我工作。
那么，对我来说呢，我已经把“cocoapods”中的“a”留下了。
