Do not report this issue to Homebrew/brew or Homebrew/core!

很显然，Homebrew不再支持10.11。它找不到make的事实很奇怪，但是我敢打赌，真正的问题是rust build需要10.12命令行工具。我有办法在OS X 10.11上安装它们吗？我有Xcode 8。

当 @ViewChild('stepper') stepper: MatHorizontalStepper; 安装新版本的 clang 和 tcl-tk 时，我遇到了同样的错误消息。在此处找到了解决方法：

Xcode 覆盖了命令行工具安装。搬家后 Xcode 到废纸篓我找到了命令行工具的目录安装：

clang --version

brew upgrade

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

另一种可能的解决方法 - 不要移动 Xcode，而是选择以下选项之一来指定 CLT 版本：

/Library/Developer/CommandLineTools/usr/bin

sudo xcode-select -s /Library/Developer/CommandLineTools

显示当前 CLT 路径：sudo xcode-select -s /Applications/Xcode.app/Contents/Developer https://github.com/pytorch/pytorch/issues/1139#issuecomment-303033942

如何在10.11上安装OS X 10.12命令行工具？
