Question

我在安装在单独分区上的Yosemite DP 7上安装Cocoapods时遇到问题。由于Stack Overflow链接上提出的解决方案相同，我已经尝试按照Cocoapods with Xcode 6 and 10.10 Yosemite和问题（https://github.com/CocoaPods/CocoaPods/issues/2219）中的说明进行操作。

我继续收到以下错误：

我怀疑这可能与我在一个单独的分区上有优胜美地的事实有关，但我无能为力。

Answer 1

我遇到了同样的问题。在按照与其他人相同的步骤拉动头发后，以下工作。

$ xcode-select --install（确认已安装命令行工具）
已安装的nvm stable（和自制程序）：$ \ curl -sSL https://get.rvm.io | bash -s stable
关闭/重新开启终端
安装ruby 2.1.2：$ rvm install 2.1
切换到：$ rvm使用2.1
卸载/重新安装xcodeproj和cocoapods

Answer 2

Xcode 6.0 GM缺少10.10 SDK，因此无法编译gem xcodeproj，其中包含一些需要10.10 SDK的C代码。这将在未来修复。现在你可以像这样解决它：

终端：sudo gem uninstall cocoapods xcodeproj
下载Xcode 6.1（目前Beta 2是当前版本）
开始使用设置 - ＆gt;位置 - ＆gt;命令行工具 - ＆gt;更改为Xcode 6.1 Beta
终端：sudo gem install cocoapods
将命令行工具更改回GM（如果您需要/需要）
