安装Xcode命令行工具 [英] Installing Xcode command line tools

问题描述

我执行了macOS Mojave 10.14的全新安装.之后，我立即从Mac App Store安装了Xcode版本10.0(10A255).

I performed a fresh install of macOS Mojave 10.14. Immediately after that I installed Xcode Version 10.0 (10A255) from the Mac App Store.

现在，我希望安装需要安装Xcode命令行工具的Homebrew.我的理解是，安装Xcode还会安装命令行工具.还是不?

Now, I wish to install Homebrew which requires Xcode command line tools to be installed. My understanding is that installing Xcode also installs the command line tools. Or not?

根据此答案，我检查了是否通过运行以下命令安装了命令行工具:

As per this answer, I checked if the command line tools are installed by running:

xcode-select -p

如下所示打印了Developer目录的路径:

which printed the path for the Developer directory as follows:

/Applications/Xcode.app/Contents/Developer

如答案中所建议，我还通过运行以下命令验证了返回值:

As suggested in the answer, I also verified the return value by running:

echo $?

重新调整了0.

我也跑了gcc和make，bash能够找到并执行它们.

I also ran, gcc and make and bash was able to locate and execute them.

到目前为止，我确信已经安装了Xcode命令行工具.现在，当我执行时:

Thus far I am convinced that the Xcode command line tools are installed. Now when I execute:

xcode-select --install

我收到此警报:

这种差异的可能原因是什么?这将两次安装Xcode命令行工具吗?还是覆盖现有安装?

What's the probable reason for this disparity? Will this install Xcode command line tools twice? Or overwrite the existing installation?

据我了解，可以无需安装即可安装Xcode命令行工具.另外，根据我以前的经验，如果不是通过Xcode单独安装命令行工具(通过运行xcode-select --install)，Homebrew不会检测到它们，即，运行brew config时，CLT:的值显示为N/A.

As I understand, Xcode command line tools can be installed without installing Xcode. Also, from my previous experience, if the command line tools aren't installed separately from Xcode (by running xcode-select --install), they are not detected by Homebrew, i.e. when running brew config, the value for CLT: is shown as N/A.

这是完整的图片(对双关语):

Here's the complete picture (pardon the pun):

尽管我是在macOS Mojave的背景下进行讨论的，但对于以前版本的macOS，问题仍然相同.

Although I am talking in context of macOS Mojave, the question remains the same with regard to previous versions of macOS.

在这里采取什么明智的方法?

What is the advisable approach to take here?

注意:安装Xcode之后，我启动了该代码，接受了许可协议，并使其完成了安装其他工具的过程(这是一次性的活动).

Note: After installing Xcode, I launched it, accepted license agreement and let it finish its run of installing additional tools (which is a one time activity).

推荐答案

在为我工作之后，只有命令行工具也可以安装.

Following worked for me, only command line tool can also me installed.

更新为 Mojave 10.14 之后，请转到 https://developer. apple.com/download/more/搜索"命令行"，然后

After you updated to Mojave 10.14 Go to https://developer.apple.com/download/more/ search for "command line" then

下载" MacOS 10.14的命令行工具"

下载dmg后，请安装软件包.

Once dmg is downloaded install the package.

验证软件包安装
