Ruby 在mac上安装CoCoapod失败

我试图按照说明在mac上安装cocoapods，但错误如下：

$sudo gem install cocoapods

ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
bad response Service Unavailable: Back-end server is at capacity 503       (https://api.rubygems.org/api/v1/dependencies?gems=cocoapods)

但有时，错误消息是不同的

$ sudo gem install cocoapods

ERROR:  Error installing cocoapods:

ruby版本：1.9.3

rake版本：10.2.2

试试这个（在OSX 10.10中为我工作）

开放Xcode 6

开放首选项

单击“位置”选项卡

将命令行工具版本更改为Xcode 6.0

卸载cocoapods

$sudo gem卸载cocoapods

安装xcodeproj

$sudo gem安装xcodeproj

安装cocoapod

$sudo gem安装cocoapods

---

运行

pod--version

验证您是否在OSX Yosemite上？是的，版本是10.9.3它不工作，错误：安装xcodeproj时出错：错误：无法构建gem本机扩展。/Users/tap4fun/.rvm/rubies/ruby-1.9.3-p484/lib/ruby/site\u ruby/1.9.1/rubygems/dependency.rb:298:'to_specs'：找不到“rake”（>=0）在总共20个gem（gem:：LoadError）中，好的，你有和我一样的问题。。。因此，首先将其输入到终端：ruby-e“$（curl-fsSL）”中，然后我该怎么办？$brew安装postgresql安装postgresql时遇到错误，错误：Homebrew不知道Xcode（6.0）版本附带的编译器版本。请

brew update

，如果没有帮助，请在

brew--config

的输出中提交一个问题：请注意，我们只跟踪稳定的、已发布的Xcode版本。
