运行xcode-select——install尝试安装，但失败，报错如下:无法安装软件，因为当前软件更新服务器上不可用。以下是对我有效的方法。

OS: Catalina 10.15.6
Xcode-select version: 2373

注意:在运行所有这些操作之前，我已经安装了xcode-select version 2373。但是移除和重新安装解决了这个问题。

卸载xcode-select

Sudo rm -rf $(xcode-select -print-path)

去应用商店下载XCode。 打开XCode。在初始加载时，它将更新/安装东西。让这一切发生吧。 从Apple Developers手动下载Xcode 12的命令行工具 安装CLT for Xcode 12包。

现在应该可以开始了。

你需要安装xcode或命令行工具

我就是这么做的，我的问题现在没了。 第一: xcode-select——print-path 给出了path /Library/Developer/CommandLineTools

so:

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

它会弹出安装窗口，只要安装，你就可以上路了。

谢谢Stackoverflow !

xcode-select --print-path

上面应该给出:/Library/Developer/CommandLineTools

sudo rm -r -f /Library/Developer/CommandLineTools
xcode-select --install

使用sudo执行以下命令，重置命令行工具。

Sudo xcode-select—reset

我猜，到目前为止，你可能已经尝试了多种解决方案，但如果这些解决方案都不适合你，别担心——我懂你的。：）

故障解决方案:

xcode-select --install didn't work for me (macOS Catalina 10.15.7) as it shows up a Software Update dialog box which says Can't install the software because it is currently not available from the Software Update Server. I also downloaded and install Xcode Command Line Tools from Apple's download website (https://developer.apple.com/download/more/?=for%20Xcode) but the problem re-appeared somehow or may be it didn't solve it in first place and I somehow didn't notice. sudo xcode-select --reset also didn't do the trick for me. Someone suggested to install whole XCode. No, thank you.

工作方案:

以下是对我有效的方法，即手动使用软件更新重新安装Xcode命令行工具。

Check if Command Line Tools Update is mentioned in your list of softwares to be updated by using following command: softwareupdate -l If Command Line Tools Update is not mentioned in that list, then manually make it part of the list using following command which will create a temporary file: sudo touch /tmp/.com.apple.dt.CommandLineTools.installondemand.in-progress Verify that the list now has the Command Line Tools mentioned by running softwareupdate -l again. Now, press Cmd+Space to initiate Mac's Spotlight Search. Search for Software Update. Start the Software Update. That will show you following kind of dialog for installing the Command Line Tools. Install away the update and be merry. :) Remove the temporary file created in Step 2: sudo rm /tmp/.com.apple.dt.CommandLineTools.installondemand.in-progress.
