在 macOS Catalina 上安装 CommandLineTools 时 Homebrew 安装程序挂起

Question

我正在尝试将 Homebrew 安装到 Intel MacBookPro (macOS Catalina) 上，但/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" 在终端中运行时，它似乎在安装 CommandLineTools 时挂起（它挂起的具体行是==> /usr/bin/sudo /usr/bin/touch /tmp/.com.apple.dt.CommandLineTools.installondemand.in-progress）。

我已经在这台机器上完整安装了 Xcode 11（据我所知，它安装了 Xcode CommandLineTools）。

导航到 /tmp 后，我发现它确实成功运行touch并创建了它运行的命令中描述的文件，但从未向其中写入任何内容。

我等了大约一个小时也没有结果。这是日志：

Answer 1

我遇到过同样的问题。我尝试安装命令行工具（CLT），但我得到了相同的查找软件对话框，一分钟后就没有任何进展。

对我来说，事实证明我根本没有 Xcode，而 CLT 似乎依赖于 Xcode。我也没有 Library/developer 目录。

我下载并安装了 Xcode，但仍然无法使用命令行安装 CLT，我还必须下载并手动安装。

获取所有安装自制程序后，不再尝试安装 CLT 并且能够成功完成其安装。

我是 Mac 新手，以前从未使用过。我在一家新公司开始工作，他们提供了它，我不确定它是否是预先使用过的，因为它已经安装了一些应用程序。也许 Xcode 已被删除或者对我来说根本不存在。本页详细解释了 Xcode 和 CLT 的整个过程 https://www.freecodecamp.org/news/how-to-download-and-install-xcode/

我会重新安装 Xcode 命令行工具：

1. sudo rm -rf /Library/Developer/CommandLineTools
2. xcode-select --install
