至于大sur..

sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install

感谢自制啤酒维护者把这有用的消息在酿造医生

通过将我的Mac更新到最新的Mac OS(即Big Sur)，一切都分解为重复要求安装Xcode-select。

这可能看起来很奇怪，但我通过重新安装并更新到最新的Xcode解决了这个问题。

这只是我解决问题的经验。

如果你想使用XCode本身提供的工具版本，你可以使用xcrun(例如xcrun git)。从下载首选项窗格底部的帮助:

注意，您可以在终端中使用XCRUN工具来启动 编译器和其他嵌入在Xcode应用程序中的工具。使用 Xcode - select工具定义激活的Xcode版本。 在终端内输入“man xcrun”以了解更多信息。

Xcode Command Line Tools can be installed as a side effect of running git --version in Terminal without Git installed. You will be prompted to install the tools as a requirement for running Git. Apple ships a binary of git with the Command Line tools. This is confirmed on the Git for Mac Download page. This seems like a valid option considering that Homebrew requires the Command Line tools to install Git as well according to another SO post. Otherwise, the previous answers are the most direct methods of install the tools.

我最近不得不通过SSH在Mountain Lion上安装Xcode命令行工具。 注意:我想这个过程对于任何版本的Xcode或OSX都是一样的。只要确保你的路径是正确的。 我是这样做的……

If you don't have a free Apple developer account, register for one Login to https://developer.apple.com/downloads Download the "Command Line Tools for Xcode" appropriate for your version of OSX For me, that was "Command Line Tools (OS X Mountain Lion) for Xcode - April 2014" Copy the dmg file to your remote In the following command, I'm using scp to securely copy the file from my local computer to the remote named remote $ scp ~/Downloads/command_line_tools_for_osx_mountain_lion_april_2014.dmg remote:Downloads/ ssh to your remote $ ssh remote mount the dmg file on the remote Here, I'm using hdiutil to mount the image $ hdiutil attach ~/Downloads/command_line_tools_for_osx_mountain_lion_april_2014.dmg install the package contained in the dmg Here, installer must be run with sudo because this package needs to be installed on the root file system $ cd /Volumes/Command\ Line\ Tools\ \(Mountain\ Lion\) $ sudo installer -pkg Command\ Line\ Tools\ \(Mountain\ Lion\).mpkg -target / unmount the dmg file $ hdiutil detach /Volumes/Command\ Line\ Tools\ \(Mountain\ Lion\) delete the dmg file from the remote; optional I see no purpose keeping it around, but you can if you want. $ rm ~/Downloads/command_line_tools_for_osx_mountain_lion_april_2014.dmg

如果你在尝试使用命令行工具时查看“控制台”，你会发现实际上有一个到Mountain Lion命令行工具的“非官方”链接!

所以试试吧:

这是我的控制台日志:
