安装好多年后，iTerm2 突然开始要求我重新安装 git？

突然之间，git当我git status在终端（iTerm2）中输入时，我的 Macbook Air（OS 12.5.1 Monterey）就开始要求我安装......

如果我说“不，我不想安装 git”，则会出现以下错误消息：

PS，我刚刚说“是”安装 git，大约花了 30 分钟，现在它又要求安装它了！我只是为了以防万一重启了电脑，但如果我说“否”，它仍然会抛出相同的消息和错误。

以下是两张截图：

为什么这种情况会突然随机发生，有什么解决方法吗？我有一段时间没有下载任何东西了，而且我很确定操作系统今天没有自动更新。也许是 iTerm2 更新了什么的……不，我尝试git status在实用程序 > 终端应用程序中运行，结果还是一样……

只是为了澄清一下，git status一直在努力多年在我的 Macbook Air 上，我最近没有更改任何内容。所以发生了一些奇怪的事情。我的硬盘上还有 85GB 的空间，所以我认为这不是空间问题......

当 Xcode 安装git为 时/usr/bin/git，它实际上只是一个小的存根二进制文件，它会调用xcodebuild来查找并执行git深埋在/Applications/Xcode.app包中的真正二进制文件。如果您的 Xcode 安装出现问题，此技巧就会失效。

如果您从 App Store 安装了 Xcode，它可能刚刚自动更新到 Xcode 14，该版本上周刚刚与 iOS 16 一起发布。Xcode 14 可能有一份新的许可协议，需要先确认才能运行任何与 Xcode 相关的程序。或者它可能发生了其他一些变化（可能是它调用与 Xcode 相关的命令行工具的方式），而这些变化可能会在 Xcode 的首次运行初始化过程中得到修复。

如果您不使用或不关心 Xcode，并且想要一个git与 Xcode 不绑定的版本，请git通过 Homebrew 或其他方式安装您自己的副本，并使用它来代替 Xcode 安装的/usr/bin/git。

顺便说一句，这与 iTerm2 无关。您可能在 macOS 的内置终端应用中遇到同样的问题。您发布的错误消息全部来自 Xcode 的部分内容（以及 Xcode 的一个片段执行的一次 Bourne shell 调用）。
