我有一些问题安装Alamofire 4.0到我的项目。
我有最新版本的Xcode，运行Swift 3，当我尝试安装alamofire时，我得到了800个编译器错误。
显然
构建Alamofire 4.0.0+需要CocoaPods 1.1.0+
[!some_cocoapod需要CocoaPods版本>= X.Y.Z，这是不满足您的当前版本，Z.Y.X.
我在终端上查看了CocoaPods的版本，它说我的版本是1.0.1。
运行更新没有起作用，我猜是因为CocoaPods 1.1处于测试阶段。
所以我不太确定如何更新到我想去的地方。 除非过时不会导致800个编译错误?这听起来像别的问题吗?

我不得不这么做，在macOS上卡住了1.9.1
Sudo gem install -n /usr/local/bin cocoapods . sh

如果您正在使用Homebrew，打开终端并输入:
brew upgrade cocoapods
如果不奏效，试试:
brew install cocoapods
之后，运行:
brew link --overwrite cocoapods
非常平滑和简单的解决方案
//MARK: -Latest stable version:
sudo gem install cocoapods --pre
//MARK: -If not work then
sudo gem install cocoapods --pre -n /usr/local/bin
//MARK: - if upper command not works you can use below mention command as well!
brew install cocoapods
brew upgrade cocoapods
brew link cocoapods
如果你启用了系统完整性保护或任何其他权限写入错误，这是自macOS Sierra发布以来默认启用的，你应该更新CocoaPods，在终端中运行这行:
sudo gem install cocoapods -n/usr/local/bin
安装后，检查pod版本:
pod --version
你将摆脱这个错误:
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /usr/bin directory
它将安装最新的CocoaPods:
Successfully installed cocoapods-x.x.x

参考这个链接https://guides.cocoapods.org/using/getting-started.html
brew install cocoapods
brew upgrade cocoapods
brew link cocoapods
如果这
sudo gem install cocoapods
给你这个错误:
Could not find a valid gem 'cocoapods' (>= 0) in any repository
试试这个:
sudo gem install cocoapods --source http://rubygems.org
