我正在尝试使用此页面上的说明(https://help.github.com/articles/using-jekyll-with-pages)安装Jekyll。但是,在第二步bundle install,输出以下内容

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

An error occurred while installing RedCloth (4.2.9), and Bundler cannot continue.
Make sure that `gem install RedCloth -v '4.2.9'` succeeds before bundling.

clang --version输出

Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.1.0
Thread model: posix

在我的机器上,Ruby是版本2.0.0p247

我已经看过很多其他人的问题,但是没有一个人有同样的问题,除了以某种方式获得捆绑包的想法之外,他们所建议的解决方案似乎也没有特别相关使用GCC代替Clang,我不知道如何完成。我的一个想法是让Clang将此视为警告而不是错误,因为此版本中的消息暗示可能,但我也不知道如何做到这一点,尤其是像bundle install这样的终端命令的上下文。我该如何解决这个问题?

我使用ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future bundle install 将错误视为警告。

sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install jekyll
