Question

我是Ruby on Rails的新手，我正在尝试创建一款应用。我运行了rails new myApp，在安装byebug时遇到了问题。

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

make failed, exit code 2

Gem files will remain installed in C:/Ruby21/lib/ruby/gems/2.1.0/gems/byebug-4.0.5 for inspection.
Results logged to C:/Ruby21/lib/ruby/gems/2.1.0/extensions/x86-mingw32/2.1.0/byebug-4.0.5/gem_make.out
An error occurred while installing byebug (4.0.5), and Bundler cannot continue.
Make sure that `gem install byebug -v '4.0.5'` succeeds before bundling.

所以看起来编译器将警告视为错误，并且byebug有警告？我需要配置编译器不将警告视为错误吗？

你应该尝试按照MarsAtomic的建议卸载/重新安装DevKit for Windows 对于Mac来说，对我有用的是运行
xcode-select --install
并在Gemfile中为byebug指定github: 'deivid-rodriguez/byebug'（不确定它是否必要）。
