ruby​​升級之後：無法構建gem原生擴展。 （EC2 Ubuntu）

Question

我試圖根據http://lenni.info/blog/2012/05/installing-ruby-1-9-3-on-ubuntu-12-04-precise-pengolin/將我的ruby版本從1.8（默認）切換到1.9.3（Pangolin的最新版本）。我正在使用apt進行此操作。

有關SO的相關問題的其他解決方案涉及apt-get install ruby1.9.3-dev但我肯定擁有它。

$ sudo gem install idn 
Building native extensions. This could take a while... 
ERROR: Error installing idn: 
     ERROR: Failed to build gem native extension.

idna.c: In function ‘toUnicode’: 
idna.c:128:41: error: ‘struct RString’ has no member named ‘ptr’ 
make: *** [idna.o] Error 1 


Gem files will remain installed in /var/lib/gems/1.9.1/gems/idn-0.0.2 for inspection. 
Results logged to /var/lib/gems/1.9.1/gems/idn-0.0.2/ext/gem_make.out 

我也檢查了我安裝了gcc和它再次從apt安裝。

$ ruby -v 
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]

我可以放棄這個。我能夠安裝punycode4r寶石，並且適用於我正在嘗試做的事。
