我认为我没有命令行工具，因此我尝试下载一些工具.发现我的XCode中没有与此相关的常规链接(它是4，而不是5，不知道为什么.如果有某种方法可以安装第五个xcode，请帮助).所以我去了苹果开发者网页，却没有找到10.9的命令行工具.我尝试使用10.8版-在尝试使用10.7版工具后，它会显示尝试安装10.7版".-它会显示尝试10.8版".

I think that I do not have command line tools, so I tried to download some. It found out that there is no usual link for this in my XCode (it is 4, not 5, dont know why. If there is some way of installing fifth xcode - please help). So I went to apple developers webpage and not found command line tools for 10.9. I tried for 10.8 - it prints "Try install for 10.7", after trying with tools for 10.7 - it prints "try for 10.8".

请帮忙.我将提供所有信息以寻求帮助.

Please, help. I'll provide all info for help.

推荐答案

TLDR:

xcode-select --install

在OS X 10.9中，命令行开发人员工具现在在使用时按需安装(这是您在稍后的评论中看到的弹出窗口).

In OS X 10.9, the command line developer tools are now installed on demand when they are used (this is the popup you mention seeing in a later comment).

第一次尝试使用某个命令行工具时，将显示弹出窗口，并且原始命令将返回并显示一条消息，提示您需要安装命令行工具，并带有错误代码.在这种情况下，问题在于ruby进程隐藏了有关需要命令行工具的消息.

The first time something tries to use one of the command line tools, the popup will be presented and the original command will return with a message that the command line tools need to be installed and with an error code. In this case, the problem is that the ruby process is hiding the message about the command line tools being needed.

如果希望显式安装命令行工具(而不是等待弹出窗口被触发)，则可以运行xcode-select --install.命令行工具包也可以从 http://developer.apple.com/downloads.

If you wish to explicitly install the command line tools (instead of waiting for the popup to be triggered), you can run xcode-select --install. The command line tools package is also available as an independent download from http://developer.apple.com/downloads.

请注意，如果系统上已安装Xcode，则不再需要单独的命令行工具包，/usr/bin中的工具将自动使用Xcode应用程序内部的工具.这就是Xcode UI不再提供为您安装命令行工具的选项的原因.

Note that if you have Xcode installed on your system, you should no longer need the separate command line tools package, the tools in /usr/bin will automatically use the ones located inside of the Xcode application. This is why the Xcode UI no longer offers the option to install the command line tools for you.
