How to update Xcode to install "UNIX Development Support"?
提问by OscarRyz
I installed Xcode a long time ago.
我很久以前安装了Xcode。
Apparently I didn't check back then the "UNIX Development Support" checkbox.
显然我当时没有检查“UNIX 开发支持”复选框。
Now I want to have them but when I click on the installation this is what appears:
现在我想要它们，但是当我单击安装时，会出现以下内容：
The UNIX Development Supportcheck box is disabled
在UNIX开发支持复选框被禁用
Q:How can I install the UNIX Development Support? Is there a way to run some script that creates all the needed links from /Developer/to /usr/bin?
问：如何安装 UNIX 开发支持？有没有一种方法来运行一些脚本，从创建所需的所有链接/Developer/到/usr/bin？
EDIT:Note: This is for old Xcode 3. Screens and tool names differ for Xcode 4 ("Unix Command Line Tools")
编辑：注意：这是针对旧的 Xcode 3。Xcode 4 的屏幕和工具名称不同（“Unix 命令行工具”）

In the Xcode .dmgfile, there is a Packagesfolder. You can manually install DeveloperToolsCLI.pkgwhich creates the link in /usr/bin.

You can also right click the "Install Xcode X.X" icon and Show Package Contents then in Contents > Resources > Packages, you will find many packages from among which resides DeveloperToolsCLI.pkg. This package installs the files you want in /usr/bin.
您也可以右键单击“安装 Xcode XX”图标并显示包内容，然后在 中Contents > Resources > Packages，您会发现其中包含 DeveloperToolsCLI.pkg 的许多包。该软件包将您想要的文件安装在 /usr/bin 中。
