ruby - sudo gem install jekyll -- 失败 -- clang 错误未知参数

Question

Jekyll 不会通过下面的 gem install 安装是错误。更远的下方是事物和位置的一些版本。

sudo gem install jekyll

在 Ruby Gem install Json fails on Mavericks and Xcode 5.1 - unknown argument: '-multiply_definedsuppress' 中遇到同样的问题

我发现本期中对 jekyll 存储库的评论很有帮助: https://github.com/jekyll/jekyll/issues/2125

如果您使用的是 rvm 或 rbenv，您可以检查 Ruby 2.1.1，它应该可以顺利安装。

否则你可以安装ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install jekyll

希望这对您有所帮助!
