MacOSX Mountain Lion上的Xcode和Git安装

Question

I just installed Mountain Lion and Xcode, so under /Applications/Xcode.app/Contents/Developer/usr/bin I found the Git directory

But when I use Git commands in the shell terminal it returns error of command not found . Any suggestions? I have many Git repos on my mac, so I would like to reuse them without checking them out again :/

Answer 1

您需要安装命令行工具（请参阅Xcode - >首选项 - >下载），或者您可以从Apple Developer下载站点下载它。

First of all, installing the Xcode Command Line tools is probably not what you want. See this post for more information:

You want to set up symbolic links or aliases that point to the versions of git (and svn etc.) that exist inside Xcode.app. This will cause you to automatically get newer versions when Xcode updates through the app store. Installing the command line tools will only confuse matters because you will end up with multiple versions of git lying around, and you will have to manually update the command line tools.

The commands you will need are:

sudo xcode-select --switch /Applications/Xcode.app # tells 'xcrun' where to look

And then in your shell profile, for example .bash_profile :

alias git='xcrun git' # use 'xcrun' to locate the git binary

Now running 'git' from the terminal will use the latest version inside Xcode.app.
