运行 Crystal 播放时出错

Question

我已检查并安装了 libevent，安装了 GCC。 LLVM 已更新。运行 Crystal 播放正常，然后因以下错误而崩溃。我可以看到本地主机输出。但它会尝试运行代码然后它会崩溃。

    Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/c++/4.2.1
Apple LLVM version 7.3.0 (clang-703.0.29)
Target: x86_64-apple-darwin15.2.0

  CPUs-MacBook-Air:~ cpu$ crystal play

查看 OSX 安装页面：http://crystal-lang.org/docs/installation/on_mac_osx_using_homebrew.html

您可能需要为 xcode 执行这些操作才能找到 libevent：

$ xcode-select --install
$ xcode-select --switch /Library/Developer/CommandLineTools
