i figured out.The problem was i was using outdated version of mavericks,i updated to the latest version and everything was working.First step is to make sure your version is up to date
我想通了。问题是我使用的是过时版本的小牛，我更新到最新版本并且一切正常。第一步是确保您的版本是最新的

This same problem stumped me for over an hour when setting up a new MacBook Pro with the latest version of High Sierra.
在使用最新版本的 High Sierra 设置新的 MacBook Pro 时，同样的问题让我难住了一个多小时。
The solution - curiously - was that:
奇怪的是，解决方案是：
- copying & pasting "xcode-select --install" failed continually, but
- typing in the same command "xcode-select --install" worked immediately.
- 复制和粘贴“xcode-select --install”不断失败，但是
- 输入相同的命令“xcode-select --install”立即生效。
(Someone else may understand why pasting a simple line of code did not produce the same result as entering it from the keyboard.)
（其他人可能会理解为什么粘贴一行简单的代码不会产生与从键盘输入相同的结果。）
