【问题描述】：
使用我的 macOS Monterey v12.6，我试图在我的 Ruby on Rails 项目中运行Bundle Install，但它停止工作。
这是我在它停止后收到的信息。

我尝试运行rails -v，这是对此的回应：

无论如何，Gemfile 中的 Rails：
gem \'rails\', \'~> 6.1.4\', \'>= 6.0.4.6\'
我已经尝试通过这个post 的解决方案来解决这个问题，但它没有解决它。
有谁知道发生了什么，我该如何解决？
-
您是否在该回溯中看到“您必须先安装开发工具”的错误消息？嗯，这就是大线索。您的 XCode 未安装或不是最新的。所以谷歌 MacOS 安装 XCode，你会在 App Store 上找到它，你会从 Apple 那里找到关于如何安装或获取最新版本的说明，
-
就像我说的那样，我确实从我提供的超链接中遵循了相同的解决方案，但没有奏效。也许我需要重新启动计算机和一切，但我安装了 XCode。
-
mkmf.log 说什么 - 它在您的错误日志中被引用？您是否真的通过命令行安装了 XCode 开发工具？我遇到了类似的问题，人们将我称为“安装 xcode”，我这样做了，但我从来没有做过关键的“xcode-select --install”……我知道你说过你遵循了上面的说明这个，但又一次 - 去过那里，忽略了我自己:)
-
@tkhobbes 感谢您提出一个好观点。我确实运行了 xcode-select --install。就我而言，我查看了日志，结果发现我必须运行附加命令 xcodebuild -runFirstLaunch 才能最终使其工作。感谢您的建议和理解我遇到的问题。 :)
