我尝试了pod install命令，但遇到此错误。

我尝试了一切，但仍然收到此错误。

解决方法

对于其他有此确切错误的人。在与我们的安全团队反复交流后，他们能够通过将 cdn.jsdelivr.net 域列入白名单来“解决”这个问题。

该问题源于我们的云安全软件（Cisco Umbrella）导致在 Cocoapods 尝试访问该域时返回 302 代码。 Cocoapods（截至本回复发布时为 v1.10.1）不处理 302 代码并抛出您在原始帖子中看到的错误。

您可以在此处看到 Cocoapods Ruby 代码抛出错误：https://github.com/CocoaPods/Core/blob/1.10.1/lib/cocoapods-core/cdn_source.rb#L372-L417
