毫不奇怪，OSX Mojave 的新更新破坏了我在 Homebrew 中的 llvm 安装，这些是我尝试的步骤:
xcode-select --install # Complained, so I installed commandLineTools from here https://developer.apple.com/download/more/
xcode-select -p /Library/Developer/CommandLineTools
xcode-select --install # Now says installed
sudo xcodebuild -license # Fails, as it says I only have CommandLineTools installed in /Library/Developer/CommandLineTools not xcode
# Try something else (all versions)
brew uninstall --force llvm
brew install llvm # yay v7 how exciting
# Only it still don't work
clang++ -std=c++17 foo.cpp -o f

有什么想法吗？我尝试过的前半部分是在网上找到的，但主要是针对 MacOS 的旧更新，也许 Mojave 以一种新的且不可预测的方式破坏了事物。
