Question

我是Ruby新手并尝试使用以下命令安装oj gem：

sudo gem install oj -v '2.1.6'

不幸的是我收到了以下错误。这是由于使用Ruby 2.0？有没有解决方法？

ERROR:  Error installing oj:
    ERROR: Failed to build gem native extension.

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/oj-2.1.6 for inspection.

这个问题是由Xcode 5.1引起的 - 它已被报告为Ruby的错误。

这里还有一些额外的讨论： Ruby Gem install Json fails on Mavericks and Xcode 5.1 - unknown argument: '-multiply_definedsuppress'
