為ruby 2.0安裝json gem時出錯

Question

我在Mac OSX 10.9上運行ruby 2.0.0p0，並嘗試安裝gem json，但不斷收到一條錯誤消息，提示它未能構建gem native擴展。

我嘗試使用以下方法更新rubygems：gem update --system，但仍然收到相同的錯誤消息。

我正在運行的ruby版本是否需要安裝其他版本的json（而非1.8.1）？

這是完整的輸出，以防出現問題：

Building native extensions.  This could take a while...
ERROR:  Error installing json:
    ERROR: Failed to build gem native extension.

將此添加到您的gemfile中

gem 'therubyracer', :platforms => :ruby

然后運行捆綁安裝。
