无法安装gem - install-tools

I am trying to install the pg gem in OSX Yosemite beta. It's giving me an error You have to install development tools first. So I try xcode-select --install and it tells me they are already installed:

我正在尝试在OSX Yosemite beta中安装pg gem。它给了我一个错误你必须先安装开发工具。所以我尝试xcode-select --install，它告诉我它们已经安装：

xcode-select: error: command line tools are already installed, use "Software Update" to install updates

xcode-select：错误：已安装命令行工具，使用“软件更新”安装更新

Anyone have any idea what's up? Is it because I'm using RVM?

任何人都知道怎么了？是因为我正在使用RVM吗？

Perhaps this problem has to do with a recent update of XCode. After a XCode update you need to do the following steps:

也许这个问题与最近的XCode更新有关。更新XCode后，您需要执行以下步骤：

Open Xcode and accept the license agreement
打开Xcode并接受许可协议
Reinstall the Command Line Tools.
重新安装命令行工具。

The second step seems to depend on your OS versions. If xcode-select --install does not work try to start the Install Command Line Developer Tools app in /System/Library/CoreServices.

第二步似乎取决于您的操作系统版本。如果xcode-select --install不起作用，请尝试在/ System / Library / CoreServices中启动Install Command Line Developer Tools应用程序。

After reinstalling the Command Line Tools try to rerun bundle install.

重新安装命令行工具后，尝试重新运行bundle install。

I was having similar issues, you can accept Xcode terms from terminal.

我有类似的问题，你可以从终端接受Xcode术语。

I believe the command is:

我相信命令是：

sudo xcrun cc

And follow on screen directions.

并按照屏幕说明进行操作。
